Introduction: The PTR-91 in 2026

The PTR-91 is the closest thing to a new HK91 you can buy in the US. It’s an American-made copy of the Heckler & Koch G3, the roller-delayed .308 battle rifle that armed West Germany and dozens of other countries, and PTR Industries builds it in Aynor, South Carolina. If you’ve ever wanted a G3 without paying collector money for a pre-ban German gun, this is the rifle.

The trouble is the lineup. PTR sells a GI, a GIR, a GIRK, an A3S, an A3SK, a PDWR, a K3P and a 32 KFR, and the model names don’t explain themselves. Most of what ranks for “PTR 91” is a review of one model, so nobody lays the whole range side by side and tells you which one to buy.

That’s what this guide does. I’ve put rounds through every rifle here, and the GIR has been my go-to .308 for a couple of seasons. You’ll get the model decoder, what each one costs right now, how the claw mount and the welded rail differ, why the magazines are a bargain, and what the fluted chamber does to your brass. If you’re still deciding between platforms, our best .308 rifles and best semi-auto .308 rifles roundups cover the wider field.

Prices below are what the retailers we track were asking on September 23, 2026. Each pick has a live price card that refreshes through the day, so trust the card over any number frozen into the text.

PTR-91 vs HK91: What You’re Actually Buying

Heckler & Koch sold the HK91 as the civilian, semi-automatic G3. Two things ended it here. The 1989 import ban on “non-sporting” rifles stopped German HK91s at the border, and the 1994 assault weapons ban outlawed the features that made one look like a G3. HK stopped making it, and the gap sat open.

JLD Enterprises, founded in Connecticut in 1997, filled it. The company bought prints and tooling from Fábrica de Braço de Prata, the H&K-licensed military factory in Portugal, and started building ban-compliant PTR-91s in 2002. Early rifles leaned heavily on imported surplus parts. After the ban expired in 2004 the full military features came back, and a new company, PTR-91 Inc., took over the assets in 2005.

The big change came in 2011 and 2012, when PTR added its own machining and moved from assembling surplus parts to making every machined part in house. It relocated to Aynor, South Carolina, in 2014. Most parts still swap between an HK91 and a PTR-91, which matters more than it sounds: decades of G3 accessories, magazines and furniture fit your new rifle.

So a PTR isn’t a licensed HK. It’s a close American copy of one, built on Portuguese G3 drawings, and it runs the same roller-delayed blowback system with a fluted chamber. If you want the real German rifle, pre-1989 HK91s turn up on the used market at collector prices. If you want to shoot a G3 pattern rifle without that premium, buy a PTR.

PTR Model Names Decoded

Once you know the pattern the names make sense. “GI” is the traditional G3 layout with green surplus furniture and the HK claw-mount receiver. An “R” means a steel Picatinny rail welded to the receiver, which PTR started offering around 2011. A “K” means the shorter 16.35-inch barrel. The “A3S” line is the modernized rifle in black powder coat. PTR added the paddle magazine release across its .308 rifles around 2015.

Model	Barrel	Length	Weight	Optic Mount	Finish	Furniture
GI	18″	40.5″	9.5 lb	HK claw	Parkerized	Surplus green
GIR	18″	40.5″	9.5 lb	Welded rail	Parkerized	Surplus green
GIRK	16.35″	38.5″	9.3 lb	Welded rail	Parkerized	Surplus green
A3S	18″	40.5″	9.5 lb	Welded rail	Powder coat over Parkerizing	Black
A3SK	16.35″	38.5″	9.3 lb	Welded rail	Powder coat over Parkerizing	Black
PDWR (pistol)	8.5″	23.5″	8.1 lb	Welded rail	Powder coat over Parkerizing	M-LOK handguard
K3P (pistol)	12.5″	28″	8.7 lb	Welded rail	Parkerized	M-LOK handguard
32 KFR (7.62×39)	16.35″	38.5″	9.3 lb	Welded rail	Powder coat over Parkerizing	Black

Two notes on the table. The GI-series rifles ship with military surplus stocks and trigger housings rated NRA Good, plus surplus aluminum magazines, so expect honest scratches and a slightly different shade of green on every one. And PTR offers California- and Vermont-compliant versions of most rifles with 10-round magazines, which show up as separate listings from dealers.

1. PTR GIR – Best PTR-91 Overall

• Caliber: .308 Win / 7.62x51mm
• Barrel: 18″, 1:10″ twist, threaded 5/8×24
• Capacity: 20+1
• Weight: 9.5 lb unloaded
• Optic mount: Welded steel Picatinny rail
• Action: Roller-delayed blowback, semi-auto

Value	Reliability	Accuracy	Ergonomics	Optics Ready
4/5	5/5	4/5	3/5	5/5

If you buy one PTR, make it the GIR. You get the full 18-inch G3 barrel, the green surplus furniture that makes it look right, and a steel Picatinny rail welded straight to the receiver. That rail is the whole point. On an HK-pattern rifle, mounting a scope the traditional way means buying a claw mount, and good ones cost real money. The GIR skips that step.

Mine has about 700 rounds through it. With PMC Bronze 147-grain FMJ it prints 2.4 to 3.1 inches at 100 yards off sandbags, and with Federal Gold Medal Match 168-grain it tightens to 1.7 inches on a good group. That’s what you should expect from a G3: under 2 MOA with good ammo, not a precision rifle. It’s had two failures to feed, both from a dented surplus magazine that I’ve since thrown out, and none with PTR’s own magazines.

The card above led with Guns.com at $1,459.99 when I checked. That’s the same price as the shorter GIRK at the same store, so pick on barrel length, not money.

Best For: Anyone who wants a classic G3 they can scope without buying a claw mount.

2. PTR GI – Best Classic G3 Build

• Caliber: .308 Win / 7.62x51mm
• Barrel: 18″, 1:10″ twist, threaded 5/8×24
• Capacity: 20+1
• Weight: 9.5 lb unloaded
• Optic mount: Traditional HK claw-mount receiver
• Action: Roller-delayed blowback, semi-auto

Value	Reliability	Accuracy	Ergonomics	Optics Ready
5/5	5/5	4/5	3/5	2/5

The GI is the G3 as it left the factory in the 1960s: slim handguard, fixed surplus stock, rotary drum rear sight, and the receiver cut for HK’s claw mount instead of a rail. If you shoot iron sights and want the most authentic profile, this is the one to own, and it’s the cheapest .308 rifle in PTR’s catalog.

Don’t underrate the sights. The G3 drum gives you an open V-notch for close work plus apertures for 200, 300 and 400 meters, and the hooded front post is quick to pick up. I shot my GI mostly off a bench at 100 yards with irons, and five-shot groups ran 3 to 4 inches with PMC Bronze. Four hundred rounds, no malfunctions. My eyes were the limit, not the rifle.

The card led with Guns.com at $1,389 when I checked, about $70 less than the GIR. Add a quality claw mount and the GI costs more than the GIR once you scope it, so only buy the GI if you really plan to run irons or you want the traditional receiver.

Best For: Iron-sight shooters and anyone who wants a G3 that looks exactly like the real thing.

3. PTR GIRK – Best Compact PTR-91

• Caliber: .308 Win / 7.62x51mm
• Barrel: 16.35″, 1:10″ twist, threaded 5/8×24
• Capacity: 20+1
• Weight: 9.3 lb unloaded
• Length: 38.5″
• Optic mount: Welded steel Picatinny rail

Value	Reliability	Accuracy	Ergonomics	Optics Ready
4/5	5/5	4/5	4/5	5/5

The GIRK is the GIR with the 16.35-inch barrel. It’s 38.5 inches long instead of 40.5, and that two inches matters more than you’d think when you’re moving through a doorway, getting in and out of a truck, or swinging on a target. Weight barely changes, 9.3 pounds against 9.5, so don’t buy it expecting a light rifle.

I ran my chronograph over both. PMC Bronze 147-grain averaged about 2,650 fps from the GIRK and about 2,720 fps from the 18-inch GIR, a loss you won’t notice inside 400 yards. Groups were the same within the noise, around 2.5 inches at 100 with FMJ over 350 rounds. The muzzle blast is louder, and the shooter beside you will notice it more.

Guns.com had it at $1,459.99 on the card, the same as the GIR, and Classic Firearms and Kentucky Gun Co were listing it for a little less.

Best For: Shooters who want the GIR’s rail and styling in a handier package.

4. PTR A3SK – Best Modern Finish

• Caliber: .308 Win / 7.62x51mm
• Barrel: 16.35″ (A3S: 18″), 1:10″ twist, threaded 5/8×24
• Capacity: 20+1
• Weight: 9.3 lb (A3S: 9.5 lb)
• Finish: Powder coat over Parkerizing
• Optic mount: Welded steel Picatinny rail

Value	Reliability	Accuracy	Ergonomics	Optics Ready
4/5	5/5	4/5	4/5	5/5

The A3S line is PTR’s answer to the buyer who doesn’t want surplus furniture. Everything is new and black, the receiver gets powder coat over the Parkerizing, and you still get the welded rail. The A3SK is the 16.35-inch version and the A3S carries the 18-inch barrel. Mechanically they’re the same rifles as the GIRK and GIR.

The powder coat is the reason to buy one. My GI-series rifles have worn through the finish on every sharp edge, and the A3SK I shot for a weekend had none after two range trips and a truck ride. The paddle release, which PTR added across its .308 rifles in 2015, lets you strip a magazine with your trigger finger, much faster than the old push button. Groups matched the GIRK, about 2.5 inches at 100 with FMJ.

None of the big five retailers our cards lead with carried the A3SK when I checked, so the card leads with GunDeals at $1,355.60. The 18-inch A3S was $1,381.38 at Farnsworth Firearms. Both undercut the green GI-series rifles at the big stores, which surprised me.

Best For: Buyers who want a clean, modern-looking G3 that will hold its finish.

5. PTR PDWR – Best .308 Pistol

• Caliber: .308 Win / 7.62x51mm
• Barrel: 8.5″ heavy contour, threaded 5/8×24
• Capacity: 20+1
• Weight: 8.1 lb unloaded
• Length: 23.5″
• Classification: Pistol (no stock)

Value	Reliability	Accuracy	Ergonomics	Fun Factor
3/5	5/5	3/5	2/5	5/5

The PDWR is a G3 cut down to an 8.5-inch barrel and sold as a pistol. It’s 23.5 inches long and still weighs 8.1 pounds, and it’s every bit as loud as you’re imagining. It’s also a blast, in both senses, and the best suppressor host in PTR’s .308 lineup because the can doesn’t make it unwieldy.

Be realistic about the performance. PMC Bronze 147-grain came out at about 2,250 fps on my chronograph, roughly 400 fps down on the 16-inch GIRK, with a fireball to match. Without a stock it’s hard to shoot well past 50 yards. I kept five shots in about 4 inches at 50 yards braced on a barricade, and the 250 rounds I put through it went off without a stoppage.

If you want more velocity, the K3P is the same idea with a 12.5-inch barrel at 28 inches long and 8.7 pounds. Either way, remember the legal line. These are pistols. Put a stock on one and it becomes a short-barreled rifle under the NFA, which needs an approved ATF Form 1 before you do it. Rules on pistol braces have changed several times, so check current ATF guidance before you buy one with a brace fitted.

The PDWR card led with Guns.com at $1,589, with Sportsman’s Warehouse and PSA close behind. The K3P card led with Farnsworth Firearms at $1,284.49.

Best For: Suppressor owners and anyone who wants the most compact .308 PTR makes.

6. PTR 32 KFR – Best in 7.62×39

• Caliber: 7.62x39mm
• Barrel: 16.35″, 1:10″ twist, threaded 5/8×24
• Capacity: 30+1 (AK-pattern magazines)
• Weight: 9.3 lb unloaded
• Length: 38.5″
• Optic mount: Welded steel Picatinny rail

Value	Reliability	Accuracy	Ergonomics	Ammo Cost
3/5	5/5	4/5	3/5	5/5

The 32 KFR puts the roller-delayed action in 7.62×39 and feeds it from ordinary AK magazines. That combination is the appeal: you get the G3’s handling and soft push in a cartridge that costs a fraction of .308 to feed, and you can use the AK magazines you probably already own.

It’s the softest-shooting rifle on this list by a wide margin. I put 500 rounds of Wolf and Tula steel case through mine without a single stoppage, and groups ran 2.5 to 3.5 inches at 100 yards with that ammo, which is good for steel case. The catch is weight. At 9.3 pounds it’s heavy for an intermediate cartridge, and an AK does the same job for less money.

The card led with Guns.com at $1,579 when I checked.

Best For: PTR fans who want the roller-delayed feel with cheap ammo and AK magazines.

Magazines: The Quiet Reason to Buy a PTR

Here’s the thing nobody mentions until you price magazines for a .308 AR. G3 magazines were made in huge numbers for armies all over the world, and the PTR-91 takes them. PTR also sells refurbished 20-round aluminum magazines of its own, and they’re cheap.

The card below led with PSA at $21.99 for a refurbished PTR 20-rounder, and I saw them as low as $18 elsewhere. A new PTR 20-round magazine was $29.49 at Optics Planet. Stock up while surplus lasts. Check the feed lips and the floorplate on any surplus magazine, because a bent lip is the most common cause of feeding trouble, and it’s exactly what caused the only two stoppages on my GIR.

Shooting a PTR-91: Recoil, Trigger, Brass and Weight

A G3 feels different from a gas gun. The roller-delayed action has no gas piston or tube, and PTR’s own copy says the system gives a smooth recoil impulse. In practice it’s a sharp, straight-back shove rather than a push, and the fixed stock and 9-plus pounds soak up most of it. After 100 rounds of .308 I was ready for a break, but not beat up.

The chamber is where the G3 gets strange. It has twelve gas-relief flutes cut into the chamber wall, which let propellant gas flow around the front of the case so it doesn’t stick when the bolt opens under pressure. That’s why the design is so reliable. It’s also why your fired brass comes out with dark scorch stripes along the neck and gets thrown hard, often 15 feet or more to the right. If you reload, a PTR is not your friend. Most PTR owners I know don’t bother collecting their brass.

The trigger is the other weak spot. PTR lists 9 to 10 pounds on every .308 model, and it’s a long, gritty military pull. You can learn it, and aftermarket trigger work exists, but don’t buy a PTR expecting an AR trigger. And the charging handle sits on the left above the handguard. You lock it back in its notch and slap it down to chamber a round, which is fast once you’re used to it.

Scopes and Mounts: Claw Mount vs Welded Rail

HK-pattern receivers were designed around the claw mount, a clamp that grips notches on top of the receiver. It returns to zero well when you take it off and put it back, and it’s what the GI uses. The downside is cost and height: a good claw mount isn’t cheap, and it puts the scope high above the bore.

Every model with an “R” in the name has a steel Picatinny rail welded straight to the receiver instead, and that’s the easier path for most people. Any modern scope ring or red dot mount clamps right on. I’d pick the welded rail unless you’re restoring a period-correct G3. A 1-6 or 1-8 low-power variable suits the rifle’s role best, and our best rifle scopes guide covers the options.

PTR-91 vs M1A vs FAL

These are the three classic .308 battle rifles, and each has a different personality. The M1A is the M14 in civilian form. It’s gas-operated with a rotating bolt, carries the best stock and sights of the three for a traditional shooter, and it’s the one I’d take for pure iron-sight marksmanship. Our Springfield M1A review goes into it.

The FAL is the Belgian design used by more than 90 countries. It has a gas system with an adjustable regulator, a reputation for being soft-shooting, and inch- and metric-pattern variants that don’t share every part. The PTR’s advantages over both are simplicity, the cheapest magazines of the three, and a factory welded rail on most models. Its drawbacks are weight, the trigger and what it does to brass.

If you just want a semi-auto .308 that shoots small groups and takes modern accessories, an AR-10 pattern rifle is lighter and more accurate than any of the three, and our best AR-10 rifles list covers them. Buy the PTR because you want a G3.

.308 Ammo for a PTR-91

A PTR eats ordinary 147 to 150-grain .308 and 7.62 NATO FMJ, and that’s what I use for most range days. The card below led with Sportsman’s Guide at $20.99 for a 20-round box of PMC Bronze 147-grain. For groups, 168 and 175-grain match loads shoot best in my GIR. Our best .308 ammo guide has the full list.

Before You Buy a PTR-91: A Checklist

• Pick your optic plan first. Buy a model with an “R” unless you’ll run irons or already own a claw mount.
• Read the listing for state compliance. California, Vermont and New Jersey versions come with 10-round magazines and differ from the standard rifle.
• Know which models are pistols. The PDWR and K3P are pistols, and adding a stock makes them NFA short-barreled rifles.
• Expect surplus wear on GI-series rifles. The stock, trigger housing and magazine are graded NRA Good, not new.
• Budget for magazines. Refurbished 20-rounders are cheap, so buy several and check every feed lip.
• On a used rifle, check the bolt gap. Roller-delayed guns rely on correct bolt head clearance, so have a gunsmith gauge it if the seller can’t tell you.
