SHOT 2014 — Rock River Arms 7.62x39mm LAR-47

By CTD Suzanne published on in Firearms, News

Team AK or Team AR? Now you can be kind of both with Rock River Arms’ (RRA) LAR-47 semi-automatic rifle. No, it is not an AK-47 wearing a Halloween costume. It is an AR-15 built from the ground up to reliably feed and shoot 7.62x39mm from (most) standard AK-47 magazines. It’s the perfect gun for the black rifle enthusiasts who hates the AK, but loves the 7.62x39mm round.

Though, Rock River Arms had to start from scratch with a newly designed upper and lower receiver in order for the rifle to accept AK-47 magazines, the LAR-47 uses a direct impingement gas system, as opposed to the AK’s piston-driven system. You can expect a well-balanced rifle that feels and operates just like an AR-15, with the exception of the odd-looking trigger guard and mag well. Internally, the LAR-47 has a heavier hammer spring than your normal .223 Rem AR and a modified bolt carrier group—all to handle the AK mags and 7.62 round without problems. The bolt and feed ramps have also been enlarged.

Currently, there are two models—the CAR A4 and Delta Carbine. Both feature a 16-inch HBAR barrel with a 1:10 twist (typical AK-47 barrel twist), a two-stage trigger, A2 flash hider with 5/8-24 thread, and an ambidextrous magazine release. The differences are slight. The CAR A4 model has a six-position CAR stock, A2 pistol grip, CAR handguards, and a gas block sight base. The Delta Carbine model has a six-position Delta CAR stock, ERGO SUREGRIP, two-piece quad rail, and a low-profile gas block. The CAR A4 is listed for $1,270, while the Delta Carbine is a bit more expensive at $1545.

If you are worried about fouling from cheap, dirty surplus ammo, RRA has you covered. The essentials—barrel and bolt carrier group—are chromed.

Early testers found that most standard AK-47 magazines feed reliably in Rock River Arms’ LAR-47 rifle, even surplus steel mags.

Will the RRA LAR-47 be the solution to the age-old conundrum “AK or AR?” We will have to wait and see. The rifles start shipping in February. RRA is currently taking preorders for the LAR-47 Delta Carbine and LAR-47 CAR A4.
