Whether you are zeroing for coyotes or running drills on steel, the Rock River Arms AR1222 LAR-15M CAR A4 5.56x45mm NATO 30+1 16″ Chrome Moly Threaded Barrel w/A2 Flash Hider, RRA 6 Position Tactical CAR Stock, Overmolded A2 Grip, Includes Carrying Case & 1 Magazine gives you a reliable, accurate platform that won’t break the bank.

Key Features

• 1 MOA Accuracy Guarantee – Rock River Arms test-fires every CAR A4 rifle and backs it with a written accuracy guarantee. Why it matters: you get a sub-MOA gun without sending it to a smith or swapping barrels.
• 16″ Chrome Moly Threaded Barrel with A2 Flash Hider – The 1:9 twist barrel is threaded 1/2×28 and comes with a rock-solid A2 flash hider. Why it matters: you can mount a suppressor or muzzle brake right away, and the chrome moly steel holds up to heavy firing schedules.
• RRA 6-Position Tactical CAR Stock – A lock-free, rattle-free carbine stock with six length-of-pull adjustments. Why it matters: you can dial in your fit for body armor, heavy coats, or a compact storage profile.
• Overmolded A2 Grip – Rock River’s rubber-overmolded grip gives you the classic A2 angle with a non-slip texture. Why it matters: your hand stays put in wet or gloved conditions, and the grip angle matches the traditional AR feel.
• Includes Carrying Case and One Magazine – The rifle ships in a padded Rock River soft case with a 30-round Magpul PMAG. Why it matters: you can head straight to the range without buying extra gear.

Who It’s For

This rifle is for the shooter who wants a factory-built, no-compromise carbine that shoots better than most custom builds. It fits the hunter who needs a lightweight, accurate .223 for varmints and predators. It suits the defensive shooter who wants a reliable, mil-spec platform with modern upgrades. And it’s for the collector who appreciates American-made forgings and hand-assembled quality from a company that’s been building ARs since the 1990s.

Pros & Cons

• Pros: Factory 1 MOA guarantee; forged receivers; threaded barrel; includes case and magazine; RRA’s lifetime warranty.
• Cons: The 1:9 twist barrel is optimized for 55-62 grain bullets—heavier match loads (69-77 grain) may not stabilize as well as a 1:7 barrel. Also, the A2 flash hider is not suppressor-optimized for quick-mount cans.
