The Rock River Arms LEF-T CAR A4 Carbine in 5.56mm (MPN LH1850) is a semi-automatic AR-15 built specifically for left-handed shooters, pairing a 16-inch chrome-moly barrel with a 1:9 twist rate. Rock River Arms equips the LEF-T with a two-stage trigger for a crisper break, a carbine-length M4-style handguard, and an RRA 6-position CAR stock with an overmolded A2 grip. The carbine feeds from a detachable 30-round magazine and ships without fixed sights, leaving it fully optic-ready, along with a Rock River carry case. Among AR-platform rifles in the AR rifles category, the LEF-T favors left-handed shooters who want factory-built ergonomics rather than an adapted right-handed rifle.
