Description
You’ve been eyeing a .308 AR platform rifle for competition or serious range work, but the price tags on some custom builds can make you wince. You need a rifle that’s ready to perform without needing a second mortgage. Look, the Armalite AR-10 3-Gun 308 18″ Barrel, Turnable Brake Adjustable Stock Black 25rd is the answer. It’s a purpose-built competition rifle from the original AR-10 maker, offering a tuned package for 3-Gun or precision shooting at a price that keeps you in the game.
Here’s the thing—this isn’t a stripped-down base model you have to upgrade piece by piece. Armalite starts with a solid foundation. The 18-inch chrome-moly barrel provides an ideal balance between velocity and maneuverability, and it’s capped with their tunable muzzle brake. That brake is a key feature, letting you adjust gas to control recoil and muzzle rise for faster follow-up shots. It’s a feature often found on rifles costing hundreds more. The rifle ships with a 25-round magazine, giving you plenty of capacity for any stage, and it’s drop-in ready for your next match or range day.
Let’s talk about the practical tradeoffs that create this value. The adjustable stock is a six-position carbine-style unit, offering a solid cheek weld and length-of-pull customization without the premium price of some high-end chassis stocks. It gets the job done reliably. The handguard is a free-float design, which is essential for accuracy as it prevents barrel contact from affecting point of impact. While it may not be the absolute lightest carbon fiber option, it’s durable and provides ample real estate for grips and accessories. This rifle is built on the proven Armalite AR-10 pattern, meaning parts like triggers and charging handles from brands like Geissele or Radian that are compatible with the Armalite spec will fit without issue.

Pros & Cons
The bang-for-buck is clear. You get a competition-ready .308 with a tunable brake and free-float handguard for $2067.99. Compared to building a similar rifle from parts or buying a higher-end brand, the savings are substantial. The Armalite name carries a legacy of reliability. On the flip side, the weight—typical for a .308 AR platform—might be a consideration for those used to lighter rifles. Some may eventually want to upgrade the trigger, though the mil-spec unit is a perfectly serviceable starting point.

It’s for the precision shooter who wants a capable .308 DMR-style platform without custom shop prices.

This rifle is available at firearms-missouri.com for Missouri residents and nationwide, with an FFL transfer required for firearm purchases.
Frequently Asked Questions
Q: Is the muzzle brake removable if I want to use a suppressor?
A: Yes. The tunable brake is threaded onto the barrel (likely 5/8×24 thread pitch, standard for .308), allowing you to remove it and install a muzzle device compatible with your suppressor. Always verify thread compatibility with your specific suppressor model.
Q: What kind of accuracy can I expect from this rifle?
A: With its free-float handguard and quality 18-inch barrel, this AR-10 is built for sub-MOA accuracy with match-grade ammunition. Using standard factory ammo, you can reliably expect 1-1.5 MOA, which is more than sufficient for competition and most hunting scenarios within the .308’s effective range.
Q: Are magazines easy to find for this model?
A: This rifle uses the original Armalite AR-10 pattern magazines, which are distinct from the more common DPMS/SR-25 pattern. While not as ubiquitous, genuine Armalite and compatible aftermarket magazines are readily available from most major retailers in various capacities.
