The Rock River Arms RRA A1 SBR 5.56NATO 10.5 30R BLK FXD is a compact AR-15 style short-barreled rifle built around a lightweight 10.5" chrome moly barrel and classic A1 carbine styling. Featuring a forged upper receiver with integrated carry handle and an A1 car triangle handguard, this SBR delivers familiar ergonomics with modern Rock River Arms precision and reliability.

This configuration is well suited for range use, training, and general recreational shooting where a shorter, handier platform is preferred. The fixed stock and semi-automatic action provide stable control and consistent performance, while the 30-round capacity supports extended strings of fire between reloads. Backed by Rock River Arms’ reputation for accuracy-focused craftsmanship, the A1 Carbine SBR offers a refined take on a proven AR-15 design.
