Since the .350 Legend cartridge made its debut in 2017, several companies have introduced series of AR-platform rifles and carbines chambered for it. The latest entry into this category is Rock River Arms with its new LAR-15M CAR A4.

The handguard is lightweight and free-floating, measuring in at 13” long. The top of the handguard has standard Picatinny rail slots with M-LOK compatible accessory points on the left, right and bottom. the upper receiver also has Picatinny slots across the top for the mounting of a verity of different optic options.  

The LAR-15M CAR A4 350 Legend comes with a RRA two-stage trigger and an enlarged winter trigger guard for ease of use with large gloves. It comes with a carbine buffer tube with six positions for the telescoping Operator CAR stock that comes standard on the model. The grip is an over-molded, A2-style pistol grip. Overall length is 33” with the butt fully retracted, and weight with an empty magazine is 6.8 lbs. The carbine comes with one 10-round polymer magazine, manual and RRA limited lifetime warranty packaged in a RRA hard case.
