The FN FAL is the battle rifle half the free world carried through the Cold War, and it’s still one of the most satisfying .308 rifles you can put on a bench. Buying one in America is the tricky part. You can’t walk into a gun shop and order a new FN. What you’ll find instead is a mix of new DSA rifles, kit builds on Imbel receivers, Argentine rifles and a handful of rare Belgian originals.

This guide sorts all of that out. We tracked every FAL our price engine could find this month, and I’ll walk you through which one to buy, what each one costs right now, the metric versus inch trap that catches first-time buyers, and how to set the gas regulator so the rifle runs soft and reliable with your ammo.

Introduction: Buying an FN FAL in 2026

Dieudonné Saive designed the FAL at FN in Belgium, and it went into production in 1953. More than 90 countries adopted it, around seven million were made, and it earned the nickname “the right arm of the free world.” The notable holdout was the United States, which went with the M14. That one decision shapes the whole American FAL market today.

Because Uncle Sam never bought FALs, there’s no big pile of US military surplus rifles to sell off. Browning imported a small batch of semi-auto FNs until ATF changed its ruling in January 1963. The 1968 Gun Control Act shut out imported machine guns, and the 1989 import ban ended most imported semi-auto versions. After that, surplus FALs came in as full-auto rifles, had their upper receivers destroyed, and were sold as parts kits for as little as $90 to $250. Hobbyists and small builders put those kits on new semi-auto receivers.

So the FAL you buy today is one of four things: a new DS Arms SA58, a kit build on an Imbel or American receiver, a used rifle from an importer like Springfield Armory’s old Imbel-made SAR-48 line, or a genuine pre-1963 Belgian G Series. If you’re weighing the FAL against other .308 battle rifles, our roundup of the best semi-auto .308 rifles covers the wider field.

Metric vs Inch: The FAL Trap Every New Buyer Hits

There are two families of FAL. The “metric” rifles follow the original Belgian pattern and were built in Belgium, Austria (the StG 58), South Africa (the R1), Brazil, Israel and Argentina. The “inch” rifles follow the Commonwealth pattern: the British and Australian L1A1 self-loading rifle and the Canadian C1. Here’s the part that trips people up. The names came from the machine tools the factories used, not from different dimensions. Both families are the same basic rifle. The parts that don’t swap are pattern differences.

Magazines are the big one. Commonwealth magazines have a lug brazed onto the front to catch the receiver, where the metric magazine uses a smaller pressed dimple. A metric magazine will sometimes work in an inch rifle if the fit happens to line up. An inch magazine won’t fit a metric rifle at all. Buttstocks don’t swap between the two either, and the L1A1 has its own folding charging handle and a two-position selector (S for safe, R for repetition) instead of the three positions most metric FALs carry.

Feature	Metric FAL	Inch FAL (L1A1 / C1)
Built in	Belgium, Austria, South Africa, Brazil, Israel, Argentina, USA (DSA)	UK, Australia, Canada, India
Magazine catch	Small pressed dimple	Lug brazed on the front
Magazines	Metric only	Inch; metric sometimes fits
Selector	Three positions on most rifles	Two: S and R
Charging handle	Non-folding on most rifles	Folding
Buttstock	Metric only	Inch only

My rule is simple. Before you buy a FAL, find out which pattern it is, then buy magazines and furniture to match. DS Arms builds metric rifles. The old Century Arms L1A1 was an inch rifle on an Imbel receiver with surplus British parts. Mix them up and you’ll own a drawer full of magazines that don’t lock in.

1. DS Arms SA58: The Best New FAL You Can Buy

• Caliber: 7.62x51mm NATO / .308 Winchester
• Barrel Length: 16, 18 or 21 in (21 in Traditional: 1:10 twist, chrome lined)
• Overall Length: 43 in (21 in Traditional)
• Weight: 8.75 lb (21 in Traditional)
• Receiver: 4140 steel upper, forged 7075-T6 aluminum lower
• Pattern: Metric, made in the USA since 1997

Price	Reliability	Accuracy	Parts Support	Collector Value
3/5	5/5	3/5	5/5	2/5

If you want a FAL to shoot rather than to collect, this is the one. DS Arms has made the SA58 since 1997, and the company built it on the same Steyr production line equipment that turned out Austria’s StG 58. It’s a metric-pattern rifle, it takes standard metric magazines, and DSA says every part is US-made. That last point matters for the parts-count rules I cover further down.

Our test rifle is a 21-inch Traditional with the fixed stock. I put 240 rounds through it over three range trips, mostly PMC X-Tac 147 grain and Prvi Partizan 145 grain FMJ. With the issue aperture sight at 100 yards, five-shot groups ran 2.8 to 3.5 inches off sandbags. That lines up with what DSA itself quotes: about 3 to 4 inches with good 147 grain FMJ. It’s a rifleman’s rifle, not a benchrest gun. On the first trip I had two failures to lock back on the last round until I opened up the gas properly, and after that it didn’t hiccup once.

The card leads with a 21-inch SA58 at $1,899.99. For reference, DSA lists its 21-inch Traditional fixed-stock rifle at $1,795 direct, but it showed out of stock when we checked in September 2026, and that’s common. The 16-inch carbines and Para folding-stock versions handle faster in a truck or a blind. The 21-inch rifle is the one that feels like a real FAL.

Best For: Shooters who want a new FAL they can run hard and find parts for.

2. Imbel L1A1: The Best-Value Inch-Pattern FAL

• Caliber: 7.62x51mm NATO
• Barrel Length: 21.8 in (L1A1 pattern)
• Overall Length: 45 in (L1A1 pattern)
• Weight: 9.56 lb empty (L1A1 pattern)
• Receiver: Brazilian Imbel upper
• Pattern: Inch (Commonwealth)

Price	Reliability	Accuracy	Parts Support	Collector Value
4/5	4/5	3/5	3/5	3/5

The L1A1 is the British take on the FAL, and in the US most of the ones you’ll see were built on Brazilian Imbel receivers. Century Arms made its semi-auto L1A1 exactly that way: an Imbel upper receiver with surplus British inch-pattern parts. Those rifles are out of production now, so what you’re buying is a used gun, and the quality depends on who assembled it and how well.

I shot an Imbel-receiver L1A1 sporter for 120 rounds of Winchester 147 grain FMJ, and it ran without a single stoppage. Groups sat around 3.5 to 4 inches at 100 yards, a hair wider than the SA58. The long barrel and the SLR stock give it a calm, heavy recoil. The folding charging handle is a nice touch, since it stays out of the way when you’re carrying the rifle.

The card shows a used Imbel L1A1 at $1,300.99 on consignment at Guns.com, which makes it the cheapest FAL on our board this month. Before you buy, confirm it’s an inch rifle and budget for inch-pattern magazines. Metric mags sometimes fit an inch rifle, but I wouldn’t count on it.

Best For: Buyers who want the classic SLR on a budget and don’t mind hunting for inch-pattern magazines.

3. Argentine FN FAL: The Best Surplus-Heritage FAL

• Caliber: 7.62x51mm NATO
• Barrel Length: 21 in (533 mm, standard FAL)
• Overall Length: 42.9 in (standard FAL 50)
• Weight: 9.4 lb (standard FAL 50)
• Maker: Fabricaciones Militares (FM), under FN license
• Pattern: Metric

Price	Reliability	Accuracy	Parts Support	Collector Value
3/5	4/5	3/5	4/5	4/5

Argentina built the FAL under license at Fabricaciones Militares, including the standard FAL, the heavy-barrel FAP and a semi-auto version called the FSL. Argentine FALs fought in the Falklands War and later showed up in Bolivia, Colombia, Croatia, Honduras, Peru and Uruguay. Surplus FAL parts kits from many countries reached the US, so a FAL sold under a country’s name is often that country’s parts on an American receiver. That’s not a bad thing. Just know what you’re paying for.

The Argentine rifle I shot had wood furniture, a strong bore and a smooth, heavy trigger. It printed about 3 inches at 100 yards with Prvi Partizan 145 grain, and it cycled every round once I set the gas. Because it’s metric, every DSA and surplus metric magazine I tried seated and dropped free.

The card leads with an Argentine-marked FAL at $2,089.99 on consignment at Guns.com. Ask the seller who made the receiver before you pay that. An FM receiver and an American receiver can both wear Argentine parts, and they’re not worth the same money.

Best For: Shooters who want real surplus parts and history on a rifle that still takes cheap metric magazines.

4. Kit-Built FALs: The Best Story in the Rack

• Caliber: 7.62x51mm NATO
• Parts: Surplus military kit (Austrian, Argentine, Brazilian, British and others)
• Receiver: New semi-auto upper (DSA, Imbel or the now-closed Entreprise Arms)
• Pattern: Metric or inch, depending on the kit
• Legal note: Must meet the federal imported-parts limit

Price	Reliability	Accuracy	Parts Support	Collector Value
3/5	3/5	3/5	4/5	3/5

When countries retired their FALs in the late 1980s and 1990s, American importers bought them as full-auto rifles. Federal law meant the upper receivers had to be destroyed, and the rest was sold as a parts kit for $90 to $250. Hobbyists and builders put those kits on new semi-auto receivers. Entreprise Arms and Century Arms both sold kit-built rifles before they stopped, and DSA still builds FALs today.

A good kit gun can shoot as well as anything on this list. A bad one will fight you from the first magazine. I’ve shot one of each. The good one, a metric build on a DSA receiver, ran 100 rounds of PMC with no issues. The bad one had a sloppy top cover and a gas plug seized with old carbon, and it short-stroked until a gunsmith sorted it out. The difference was the builder, not the parts.

The card leads with a DS Arms-built rifle listed as a “Lebanese FAL” at $2,299.99 on consignment at Guns.com. The listing name is all we have, so ask the seller which parts kit and receiver it uses. At that price you’re paying for the story as much as the rifle, since a new SA58 costs less on our board this month.

Best For: Collectors who want a rifle with a real service history and know how to inspect a build.

5. FN FAL G Series: The Collector’s Grail

• Caliber: 7.62x51mm NATO
• Maker: FN Herstal, Belgium
• Importer: Browning Arms Company
• Imported: 1959 to January 10, 1963
• Number imported: 1,836, plus 12 added to the exempt list in 1974
• Configurations: Mostly standard, some heavy barrel and Para

Price	Reliability	Accuracy	Parts Support	Collector Value
1/5	5/5	3/5	4/5	5/5

Browning started importing semi-auto FALs from FN in 1959. ATF looked at a sample and ruled it wasn’t a machine gun, since the selector couldn’t reach the full-auto position and the auto sear wasn’t there. Browning brought in 1,836 rifles by January 10, 1963. On that date ATF changed its standard: a FAL that could accept an auto sear at all would now count as a machine gun under the NFA. The rifles already here were grandfathered and listed by serial number, and 12 more were added in 1974.

That’s why G Series rifles sit at the top of every FAL collection. They’re genuine Belgian FNs, and they’re legal to own as semi-autos. I got to handle one at an auction preview. It feels like any other well-kept FAL until you remember what it costs.

The card shows a G Series rifle at $18,700.99 on consignment at Guns.com. At that money, get the serial number checked against the exempt list before anything else. A mismarked or doctored rifle is a very expensive mistake.

Best For: Serious collectors who want the one FN FAL Americans could legally buy new.

How to Set the Gas Regulator on a FAL

The adjustable gas system is the FAL’s secret weapon. A short-stroke piston sits above the barrel, and a regulator behind the front sight base lets you bleed off gas the rifle doesn’t need. Set it right and the rifle cycles reliably with softer recoil and less wear. Leave it wide open and you’ll get short strokes. Leave it closed and it slams around, beating up the brass and the rifle.

Here’s the method I use, which matches the procedure published by the NRA’s Shooting Illustrated and DSA’s own advice:

1. Open the regulator all the way, so the 7 setting shows on top.
2. Insert an empty magazine, load one round through the ejection port, and fire. The bolt shouldn’t lock back.
3. Turn the regulator one click toward the gas block (to the right, looking down from the top of the handguard) and fire one round again.
4. Repeat until the empty magazine locks the bolt open, then fire several more single rounds to confirm it does it every time.
5. Once it’s reliable, go two more clicks toward the gas block for a safety margin.

My SA58 started locking back at setting 4 with PMC X-Tac, so I run it two clicks past that. Redo this whenever you change ammo, since different loads give different pressure. The regulator is also why the FAL keeps running when it’s dirty: you can give a carbon-caked rifle a bit more gas and keep shooting.

FAL Magazines and Ammo

Most FAL magazines hold 20 rounds, and metric ones are easy to find. The card below tracks metric-pattern FAL magazines only. If you own an inch-pattern L1A1, buy inch magazines for it.

The magazine card leads with a Thermold 20-round FN FAL magazine at $19.99 at Sportsman’s Guide. I keep a few steel surplus magazines for serious use and polymer ones for range days, and all of them ran fine in the SA58.

On ammo, DSA says it’s safe to shoot both 7.62x51mm NATO and commercial .308 Winchester in its FALs, with a preference for NATO-spec ammo. Stay as close to 147 grain bullets as you can. DSA doesn’t recommend heavy or high-powered hunting loads, ballistic or soft-tipped bullets, or any steel-cased ammo, so the card below leaves steel-cased and soft-point loads out.

The ammo card leads with ZSR 149 grain M80 FMJ at $15.99 for 20 at Palmetto State Armory. That’s the kind of brass-cased ball ammo the FAL was built around. For hunting and defensive loads in the same caliber, our .308 ammo guide goes deeper.

FAL vs PTR-91 vs M1A: Which .308 Battle Rifle?

These three are the classic Cold War .308 battle rifle patterns you can still buy. Each one works differently, and that’s what should drive your pick.

Rifle	Pattern	Operating System	What It Does Best
FN FAL / DSA SA58	Belgian FAL	Short-stroke gas piston, tilting breechblock, adjustable gas	Soft, tunable recoil and easy field stripping
PTR-91	German G3 / HK91	Roller-delayed blowback	Rugged simplicity and cheap magazines
Springfield M1A	US M14	Gas-operated rotating bolt	Iron-sight accuracy and a traditional stock

I like the FAL best of the three for long range days. The adjustable gas takes the sting out of .308, and the rifle breaks open like a shotgun for cleaning. The PTR-91 is harder on brass and has a heavier trigger, but it runs on almost anything. The M1A is the most accurate out of the box of the three and feels the most like a hunting rifle. Read our Springfield M1A review if that sounds like you, and see our list of the best .308 rifles for bolt guns and AR-10s.

FAL Laws: Para Stocks, Short Barrels and the Parts Count

Every rifle on this list is semi-auto only, so a standard 16-inch or longer FAL is an ordinary rifle under federal law. Three things can change that.

Short barrels. A rifle with a barrel under 16 inches is a short-barreled rifle under the National Firearms Act, and it needs ATF registration before you build or buy one. DSA’s short OSW model falls in this group when it’s built with a stock.

The imported-parts count. Federal rules (27 CFR 478.39, the section people call 922(r)) say you can’t assemble a semi-auto rifle using more than 10 of 20 listed imported parts if the finished rifle couldn’t be imported. The list includes the receiver, barrel, bolt, bolt carrier, gas piston, trigger parts, stock, pistol grip, handguard and magazine body, follower and floorplate. Kit builds use US-made parts to stay under that count, which is also why DSA’s all-US-made parts matter.

State laws. Several states, including California, New York and New Jersey, restrict semi-auto rifles with features like folding stocks, flash hiders or detachable magazines. A Para folding-stock FAL is exactly the kind of rifle those laws target. Check your state’s rules before you order one.

What to Check Before You Buy a Used FAL

• Metric or inch. Confirm the pattern first, then buy magazines and furniture to match.
• Who made the receiver. DSA, Imbel, FN, FM or a small shop. It’s stamped on the rifle, and it’s most of the value.
• Gas plug and regulator. They should turn and click freely. A seized regulator means the rifle hasn’t been cleaned in a long time.
• Bore and crown. Look for a bright bore and an undamaged muzzle. Surplus parts can hide a worn barrel.
• Headspace. Have a gunsmith check it on any kit build you didn’t assemble yourself.
• Parts count. On a kit build, ask which US-made parts it uses to stay legal.
• G Series serial. On any rifle sold as a G Series, check the serial against the ATF exempt list.

Where to Buy an FN FAL

The cards on this page pull live listings from retailers we track, and Guns.com carries most of the used FALs on our board. For new rifles, DS Arms sells direct through your local dealer, though popular models sell out. For rare rifles and G Series guns, auction houses and GunBroker are where most of them change hands.

If you’re shopping the wider surplus market too, our used rifles hub tracks bolt guns and battle rifles side by side, and our guide to where to buy vintage guns covers auction houses and collector dealers. The FAL’s bolt-action ancestors are covered in our Mauser rifle guide and our Lee-Enfield guide.

For a first FAL, keep it simple. Buy a metric rifle, preferably an SA58, set the gas for the ammo you’ll shoot, and spend the rest on magazines and 147 grain ball.
