Description
The Rock River Arms LAR-15M CAR A4 complete upper delivers the .350 Legend cartridge to your AR-15 lower. This straight-walled round is approved for hunting in many states that restrict bottleneck centerfire rifles, and it drops onto a standard AR-15 lower using familiar controls and STANAG-pattern magazines. Built around a 16″ heavy stainless steel barrel with a 1:16 twist, the upper is mated to a forged A4 upper receiver and finished off with RRA’s signature Operator muzzle brake for fast, flat recoil control.
The barrel is cryogenically treated for long-term dimensional stability and consistent accuracy downrange. A 13″ free-float M-LOK handguard gives you plenty of rail space for lights, lasers, or a bipod without adding unnecessary weight out front, and the low-glare black finish on the receiver and handguard pairs cleanly with any standard AR-15 lower. Rock River Arms ships this upper with a bolt carrier group, charging handle, and one 10-round magazine, so all you need is a compatible lower to get shooting.
Drop it on a dedicated hunting build for whitetail-sized game at woods ranges, set up a fun and affordable .350 Legend plinker that shares controls and ergonomics with your other ARs, or keep one assembled as a low-recoil option the whole family can enjoy. Either way, you get the fit, finish, and accuracy Rock River Arms is known for in a complete, ready-to-install package.
