Rock River Arms CAR A4

The Rock River Arms CAR A4 is a proven AR-15 platform rifle chambered in 5.56x45mm NATO (also accepts .223 Remington). Built on forged LAR-15 lower and A4 upper receivers, it features a 16" chrome-moly barrel with 1:9 twist, A2 flash hider, and carbine-length gas system with A2 front sight base. Lightweight at just 7.1 lbs with a collapsible stock, this rifle delivers reliable performance and guaranteed 1 MOA accuracy at 100 yards.

Key components include a crisp two-stage trigger, overmolded A2 pistol grip, and RRA 6-position tactical CAR stock for adjustable length of pull. The forged A4 flat-top upper is optic-ready, while the fixed A2 front sight provides a durable iron sight option. Standard carbine handguards and 1/2"-28 threaded muzzle complete the classic yet versatile configuration.

Ideal for duty use, home defense, competition, or general range work, the CAR A4 offers familiar AR ergonomics with Rock River Arms' renowned build quality. This package includes one 30-round magazine and a fitted RRA hard case, making it ready for immediate use straight out of the box.
