Update: Covid-19, riots across America and now a change in government mean that gun stocks are stretched wafer thin. That includes winchester semi-auto 308 rifles.

Also, these will sell out fast. We’re monitoring constantly, but if you just want to see which semi-automatic 308 rifle you can buy right now, these live links will show you what’s in stock today.

The Best Semi-Auto 308 Win Rifles For Sale

Semi-Auto 308 Win Mag rifles are AR-15s taken to a new level entirely. They are battle rifles in the truest sense, and they are also seriously popular hunting rifles.


It used to be that a semi-auto wasn’t as accurate as its bolt-action brethren. But that has become one of those urban myths. While technically there’s a kernel of truth in there, there is no practical difference unless you’re punching paper at 1000 yards.


Even then, chassis rifles and hybrid precision rifles are still leaning towards the Modern Sporting Rifle design. And 308 Winchester Semi-automatic rifles are appearing more and more in target shooting competitions.


With a hog hunt, range shooting or even home defense, it is worth its weight in gold. That’s good, because there is often a serious weight penalty to pay. A lightweight AR-10 is a rare find, but we’ve got a few…


Now, which is the best semi-auto 308 Win Mag rifle for sale in 2022?

19 Best Semi-Auto 308 Rifles for Sale – Sep 2022

1. Smith & Wesson M&P10


  • Price: $1,084.99
  • Barrel length: 16 inch
  • Total Length: 34 inch
  • Capacity: 20+1
  • Weight: 8lb


This is the classic Colt M4 clone 308 Winchester AR-10. It’s the matte black rifle you pictured in your head when you clicked the link.


It is also 8.1lb without any of the fancy technology you find on other 308 Winchester semi-auto rifles here. Just simple, pared down polymer and steel with a Black Armonite finish.


You get a collapsible stock, some of them have M-Lok handguards, others have the classic Vietnam era forend. All of them offer spectacular bang for the buck.


There’s nothing standout except the price, but this is a good, honest, 308 Winchester rifle that will do everything you want.


If you want to level up, head to the Smith and Wesson Performance Center, who can sell you a semi-automatic rifle sniper system. Or just scroll down. We got more expensive space age stuff for you here.


As an all-rounder, and even a big game hunting rifle up to 500 yards, though, this is the one multitool you need. With this price tag, that’s good enough for the overall win.



Christensen Arms CA-10 DMR on sale. Is this the best 308 rifle in the world? It might be you know. Get yours here.

2. Christensen Arms CA-10 DMR


  • Price: $3,299.99
  • Barrel: 18 inch
  • Total Length: 39 inch
  • Capacity: 20+1
  • Weight: 7.1lb


Simple availability is one reason the Christensen Arms CA-10 DMR is riding high at the moment. You can buy one, which makes it the best custom 308 Win semi-auto rifle for sale in 2022.


Seriously you even get a choice of colors: Burnt Bronze, Tungsten Grey and Matte Black Cerakote finish. They even have barrel length options for your Designated Marksman Rifle, with 18 and 20 inch barrels.


At a time when nothing is available, that’s crazy.


Also, It’s a Great 308 Rifle


Look beyond the logistical supply chain problems of 2022 in the firearms industry and you’ll see a beast of a gun that’s number one pretty much on merit.


The Christensen Arms CA-10 DMR is the complete AR-10. It’s light enough to shoulder all day and yet capable of delivering all that 308 punch. It will probably match the range of most full on sniper rifles too, in a layman’s hands.


Lightweight materials, mainly carbon-fiber, contribute to a lightweight 308 Semi Auto. That barrel is CF-wrapped steel, the handguard is carbon fiber too and the end result is a sublime piece of balanced engineering.


Yes CF parts cost a little more to maintain and replace. But they also give you an absolutely stellar battle rifle that can give you the competitive edge when it comes to home defense. Or it can be your main hunting rifle.



Rock River Arms LAR-8 X-1 rifle on sale now. A sub-MOA semi automatic 308 Winchester sniper. Great for home defense.

3. Rock River Arms LAR-8 X-1


  • Price: $1,734.99
  • Barrel Length: 18 inch
  • Total Length: 35.3-39 inch
  • Weight: 9.5lb

This is a budget conscious Designated Marksman Rifle that promises sub-MOA performance out the box.


If you want a simple 16 inch barrel patrol rifle, go for the M4. This is the long-range rifle that gives you options for home defense and some hunting scenarios.


That weight is a bitch and you’d really have to be a committed hunter or professional sniper to shoulder 9.5lb on a hike.


But this Rock River Arms is a rifle law enforcement and military rely on each and every day.


If you don’t see the added weight as a penalty and you like a thicc rifle, well this one works.


Armalite AR-10 Tactical. A great 308 Winchester rifle for defense and just about everything else, at the right price.

4. Armalite AR10 .308 Tactical


  • Price: $1.799.99
  • Barrel Length: 16 inch
  • Total Length: 39.5 inch
  • Weight: 8.4lb

Armalite will forever remain intertwined with the AR-15. And none of these Modern Sporting Rifles would have happened without it. So, in a way, Armalite started this whole thing.


That doesn’t really matter now. What does matter is that this is a high quality rifle and the customer service team has been working overtime to keep stock flowing in 2022.


Euro Optic even had an SBR and a few other options you might want to consider. But this is the mid-range tactical rifle that we think could be the pick of the bunch.


Daniel Defense DD5 V3 308 Rifle. A great 308 Winchester semi-automatic AR-10.

5. Daniel Defense DD5 V4 308 Rifle


  • Price: $3,009.99
  • Barrel Length: 18 inch
  • Total Length: 35.3-39 inch
  • Weight: 8.6lb


The Daniel Defense is objectively as good as anything here, and on another day could be your overall winner. You know it’s that tight at the top and there is no reason not to buy a Daniel Defense battle rifle really.


This is slightly heavier than the lightest here, but so much cheaper and more mainstream that we think it would win the popular vote.


Daniel Defense make great AR-15s that are consistently among the winners of our $2000 AR-15 and custom AR-15 categories. It also makes great sniper rifles and big battle rifles, as it turns out.


DMR That Beats the Military Standard

There are lots of rifles the average soldier would rather take into battle than the contract-supplied hardware in their hands.


You can guarantee that the Designated Marksman would take a long-range Daniel Defense rifle in a heartbeat. If his country could afford it. But you can. So do it.



Diamondback AR10 for sale. A cheap 308 battle rifle.

6. Diamondback DB10


  • Price: $1,015.99
  • Barrel: 16 inch
  • Capacity: 20+1
  • Weight: 8lb


The Diamondback AR10 is another surprisingly solid option if you’re looking for an affordable DMR or beefed up defensive rifle.


Diamondback Firearms makes some great semi auto rifles and always gives value for money. Here, in the midst of a wave of $4000 firearms, you’ve got a $1000 lump of hardware that is 90% of the rifle for 25% of the money.

7. FN SCAR 17S


  • Price: $3,696.00
  • Barrel: 17 inch
  • Total Length: 28.5- inch
  • Capacity: 20+1
  • Weight: 8lb


If you’re looking for the ultimate 308 battle rifle, well the FN SCAR 17S could make a legitimate claim to that title. This is a US Military service weapon, minus full auto.


You have to admit, that’s kind of badass in itself.


This is a short-stroke, gas piston operated rifle and the Scar 17S comes in .308 Win.


FN Can Suck Your Money Like a Meth Addiction


Some people need to be careful with FN rifles. The FN SCar 17S can turn into an addiction that means your quality of life can actually suffer. Why? Nobody is really sure, but there’s an aesthetic, a level of engineering and a certain FN way of doing things that can turn you into one of those enthusiast bores at parties.


If you’re nodding along, you probably already know that today is about to get expensive. You know it’s something to do with that creamy short stroke gas piston system, but not much more.


Worry about it tomorrow. It’s fine… Just place your order now. Like you know you want to.


The chrome-lined barrel and free-floating handguard is sexy. It’s fully ambidextrous, which is nice for left-handed shooters, and it is basically bulletproof.


It’s also one of the most famous and instantly recognizable rifles on the planet. And you do kind of want to own a Scar 17S. Get yours now.


Springfield Saint Victor 308 rifle on sale now.

8. Springfield Armory Saint Victor 308


  • Price: $1,438.99
  • Barrel length: 16 inch
  • Total: 37.75 inch
  • Weight: 7.11lb


The Springfield Armory Saint Victor 308 Winchester is a minimalist AR-10 that manages to sneak under the 8lb bar. By quite a margin.


Now that’s a significant psychological barrier and puts this gun into elite company. And it gets there for about half the money.


Patrol and Light Hunting, Not a DMR


A semi automatic rifle like this is good for target shooting and it’s even a hunting rifle for big game and medium game in North America.


But they’re really battle rifles at heart. So you get an M-Lok rail for tactical gear. The full-length Picatinny rail is interrupted to save weight and the black synthetic Bravo Company Manufacturing buttstock is lightweight too. The charging handle is decent as well.


Availability has been a problem during the great 2022 guns shortage. But if you can see one, don’t be put off by the low price. This is everything you need, and nothing that you don’t.



Wilson Combat AR-10 Ranger

9. Wilson Combat AR-10 Recon Tactical


  • Price: $3,285
  • Barrel: 16 inch
  • Total: 32.5-37.75 inch
  • Weight: 8lb

Only the 5-8 week delivery time is holding the Wilson Combat AR-10 Recon Tactical off the top spot. It’s really that close between these custom gunsmiths.


If you can wait for your 308 Winchester Semi-automatic rifle, this might be the perfect choice.


Are Wilson Combat Rifles Worth the Money?


Well isn’t this a can of worms of a question….


These custom rifles are expensive, and you could also argue that this is better value for money with the custom carbon fiber parts. And you’d have a point.


But you’re paying for the peace of mind that goes with owning one of the finest semi-automatic rifles. You’re paying for the obsessive R&D on 20 abandoned handguards and 30 stainless steel recipes.


You’re paying for the countless hours of quality control, experimentation with third party suppliers and the thousands of hours in the field.


This Rife Doesn’t Miss, You Do…


Also, you’re paying for the definitive knowledge that this rifle is spot on, and if you miss then it’s probably your fault.


Some people like having to raise the game to the Porsche in the hands, rather than blaming an old Ford for screwing up. And that’s fine too.


It’s just on-point engineering at every single step of the process. It’s mechanical engineering beauty in its own way, like a Swiss watch.


Nice things cost money. That’s a sad fact. But the Wilson Combat is one of those investments that will put a smile on your face every time you lay eyes on it in your gun safe. You don’t even need to fire it to feel the quality.


H&K MR762A1 Long Range Precision for sale. Get this legendary 308 precision shooter here.

10. HK MR762A1 Long Range Precision


  • Price: $7,413.95
  • Barrel: 16.5 inch
  • Total: 36.5-40.5 inch
  • Weight: 10.42lb
  • Capacity: 20+1


You are either shaking your head at disgust at the price or mashing the buy it now button. There doesn’t seem to be a grey area here…


We are the first to concede that the HK MR762A1 LRP is a total Crackpipe of a retail price.


Also, we would encourage you to look at perfectly serviceable rifles on this list for about half the money. But then if you really want the HK then it doesn’t really matter what we say. And we know that too.


This is essentially Heckler & Koch’s military hardware, a semi-automatic sniper rifle so accurate and reliable that it become an official supplier. The HK is known as the US Army’s Compact Semi-Automatic Sniper System (CASS) and Squad Designated Marksman Rifle.


Expensive Mods You Can Do at Home

You can also look at it as a modified battle rifle, with some basic parts you can buy online. And you would be right too.


It really is the HK MR762 with a Vortex PSTII scope, cheekrest on the HK G28 stock, heavy barrel, Harris bipod, M-Lok handguard and a pelican case. I think you could buy those things in about 5 minutes, for less…


But if you want the legendary HK reliability. If you want that piston system that’s so good it’s basically banned on these shores, then that’s all good too.


It’s your money. You can buy a Ferrari. Buy a Dually. Buy a HK. It’s all cool…


FN SCAR 20S for sale. A custom sniper rifle in 308 Winchester

11. FN Scar 20S


  • Price: $4,100.99
  • Barrel: 20 inch
  • Total: 42.5 inch
  • Capacity: 10+1
  • Weight: 11.2lb


This is the longer barrel, long-range version of the legendary FN SCAR that troops around the world have taken into battle with select fire and a full auto switch.


This is the precision rifle, a marksman’s special and a target shooter extraordinare. For FN to give us a sniper rifer without a bolt-action, they must agree with us about bolt actions offering no real world advantage.


FN took inspiration from the Mk 17 and Mk 22 SSR rifles chambered in 308 Winchester.

This is a gas-piston design, which is kind of the least you’d hope for at this price, and that sturdy frame and long footprint mean recoil isn’t a real problem. The upper receiver and flat top really make it look like


Military Gun Now a Civilian Paper Puncher

This is really a target shooter’s gun, but the semi-automatic FN might also be the perfect hunting gun if you go on safari. Or if you hunt from towers or hides. People do that, and then the weight of the gun is less of an issue.


With an 800-yard range, and more in competent hands, the FN SCAR 20S is becoming a firm favorite with serious hobby shooters. The monolithic receiver, full-length 1913 rail and 20 inch stainless steel barrel all contribute to a rock steady tack driver.



PSA Gen3 PSA10. A 308 Winchester AR Style rifle that's cheap, effective and pretty light. Is this a good 308 starter rifle? Yes.

12. Palmetto State Armory Gen3 PA10


  • Price: $849.99
  • Barrel: 18 inch
  • Total Length: 36 inch
  • Weight: 8lb
  • Capacity: 20+1

Palmetto State Armory makes cheap Modern Sporting Rifles, and now pistols, that have established a cult like following with those that like a bargain.


You get a Palmetto State Armory patrol rifle at a great weight with a stainless steel barrel and forged aircraft-grade aluminum receivers. The Bolt Carrier Group is Nitride coated, it’s a flat top upper receiver and full-length rail. An ambi charging handle too. On paper it’s good.


And for the money you spend, the Palmetto State Armory rifle gives outstanding bang for the buck. There are other budget rifles that are close enough to this price point to get my vote. But the PSA 308 rifle is still a great starter rifle that shouldn’t let you down.


Springfield Armory M1A Scout Squad rifle on sale now. Get your World War II inspired semi-automatic 308 rifle today.

13. Springfield Armory M1A Scout Squad


  • Price: $1,879.99
  • Barrel: 18 inch
  • Total: 44.3 inch
  • Weight: 8.8lb


The M1A Scout is an oddity in this company, if not a complete wildcard.


I mean it’s not an AR-10, but it basically matches the numbers of anything else here and comes with a detachable box magazine. So yeah


Yes this is an old-school scout rifle, based on the M1 Garand that helped to win World War II. But it’s also a simple rifle, designed for all-round use and shouldering all day on long marches. So the Scout Squad was always a kind of lightweight 308 rifle.


Pretty useful thing huh? And that’s why the M1A in various forms is still popular with Law Enforcement. When they need a little more range, but don’t want to deal with a bolt action, this works. When they’re getting shot at, is one such occasion.


The Springfield M1A comes with a composite stock with a forward-mounted optical sight base. That’s a rail up front, and folding iron sights. Just in case you’re a time traveler from the last century.


Springfield Armory M1A SOCOM For Sale

Springfield M1A SOCOM is Nuts


Now you can get a number of different Springfield M1A finishes, including the ever so slightly batshit nuts Springfield M1A SOCOM.


That’s like a steampunk AR-15 and, aesthetically at least, the Springfield M1A is one of our favorite rifles on sale in 2022. Not technically the best battle rifle, by any stretch of the imagination. But the Springfield M1A SOCOM is guaranteed to make you smile every time you flip up the iron sights.


Is this a valid comparison? Yeah, actually it is.


There are a range of national match steel barrel and new editions all the time, as well as California legal rifles. So check here for a general M1A search that should show you everything you can actually buy right now.


Savage MSR 10, a great 308 rifle you can buy today.

14. Savage Arms MSR 10 Hunter


  • Price: $1,417.99
  • Barrel: 16.1 inch
  • Total Length: 26 inch
  • Weight: 7.8lb
  • Capacity: 20+1


The Savage Arms MSR 10 Hunter could easily feature higher on this list, but it’s going against some real stars att he moment and this is how the cookie crumbled on this particular day.


But the Savage Arms is still a great AR10 and one of the better gun deals you’ll find. The company is really known for its barrels, but has steadily built a reputation for great gun deals and good value, with firearms that punch well beyond their price bracket.


This one is no different, and you won’t be disappointed.



19 Best Semi-Auto 308 Rifles for Sale – Sep 2022

15. Kel-Tec RFB Carbine


  • Price: $1,734.99
  • Barrel: 18 inch
  • Total Length: 26 inch
  • Weight: 8.1lb
  • Capacity: 10+1


If you like compact, lightweight AR-10 semi automatic rifles, then you really should take a look at the Kel-Tec RFB bullpup rifle.


The whole gun isn’t much longer than the average AR pistol. But it packs in a full 18 inch barrel, a detachable box magazine and this is one of the more elegantly designed battle rifles here.


It solves problems the heavier AR-10s just tolerate and work round. This is intelligent design, a great battle rifle and it’s also a really, really good gun.


IWI Galil Ace, a 308 rifle with an AK47 pistol feel. Buy yours today.

16. IWI Galil Ace Gen 2

  • Price: $2,039.99
  • Caliber: 308 Winchester
  • Barrel: 16 inch
  • Weight: 8.75lb
  • Capacity: 20+1

The Russian influence is clear to see in this hybrid rifle that looks something like the lovechild of an AK pistol and an AR-15. It’s awkward, but we like the IWI Galil Ace.


Is this Galil Ace different enough? Definitely for a place on this board and we do kind of like this rifle in other calibers. You can order a Galil Ace in 7.62×39 and that really feels like its natural habitat.


Of course you can get a Galil Ace in 5.56 NATO, too. But it’s much more of a left-field choice in that caliber.



Stag Arms STAG-10 308. A great Winchester Magnum rifle you will love for home defense and hog hunting.

17. Stag Arms STAG-10

  • Price: $1,554.99
  • Caliber: 308 Winchester
  • Barrel: 16 inch
  • Weight: 8.1lb
  • Capacity: 10+1

Owners would put their Stag Arms against most of the other AR types here and they may have a point, it’s coming down to fractions here honestly.


The price counts against the Stag, but apart from that these are solid 308 Winchester semi-auto rifles.


Century Arms C308, a cheap 308 rifle that is easily a match for many more expensive AR-10s chambered in 308.

18. Century Arms C308


  • Price: $699.99
  • Caliber: 308 Winchester
  • Barrel: 18 inch
  • Total Length: 26 inch
  • Weight: 8.1lb
  • Capacity: 10+1

If you want a cheap 308 AR-style rifle and you can compromise a little, then the Century Arms C308 has a lot going for it. It’s basically a HK91 clone, which isn’t a bad start for a tactical rifle as it turns out.


The Mauser STG-45, a variety of Spanish CETME rifles and the HK are all kind of related. But this is really a clone of the HK and comes with that iconic and famously reliable roller-delayed blowback system.

The simple folding stock and minimal window dressing gives a gun that tips the scales at just over 8lb too.


So it’s portable, it’s reasonably accurate up to 400 yards and it comes from the same company that makes all the modern AK-47s and Draco guns.


There are other guns that don’t cost much more and will give you a better ownership experience. But if money is the number one priority, you could do a lot worse than this.


Best Place for AR-10 Parts and Accessories


You can upgrade more or less every part of your 308 with the likes of an Aero Precision cold hammer forged barrel. The steel barrel is one of the easiest upgrades. It will yield the best results if you opt for the likes of Aero Precision and fit it well to a good basic upper receiver. Maybe a new gas block, it depends.


A National Match grade steel barrel will turn most 308 rifles into a sniper. All of hte upper receiver options here are a good start.


Although some are obviously better than others, and some are so good that an Aero Precision steel barrel would be a downgrade. Just treat them to National Match grade ammo instead.


A gas block, new front sight and a chromed bolt carrier group could all find their way into your shpping cart before long. But if that happens, then you have some kind of love affair going with your 308 Semi Auto rifles. So it’s all good, right?


Parts and accessories are everywhere, from the likes of Grey Ghost Precision, Knights Armament and more. Where do you get yours? It’s a free world, but we have some suggestions. We also helped you with searches and direct links to save you time.


Sig Sauer Cross for sale, a lightweight precision rifle for all your needs

What About a Sig Sauer Cross?

Now you don’t have to tell us that the Sig Sauer Cross is a bolt action rifle, but it does deal with a lot of the issues that might make you dismiss precision rifles for the field.

First, it’s seriously light. At 6.8lb you can shoulder it all day, and it largely looks and feels like a pretty solid Sporting Rifle. The Sig Sauer in 308 Winchester is an option, is all we’re saying, especially if you’re left handed.

You’ll find these at Palmetto State Armory, and on Guns.com. So get yours today.

What About a Concealed Carry While You’re Here?
