Colona, IL (March 2026) – Rock River Arms, the industry’s most respected name in Modern Sporting Rifles and pistols, wants to remind everyone that the newly implemented “zero tax” on NFA items doesn’t only apply to suppressors but also to Short-Barrel Rifles (SBRs). To celebrate, RRA introduces the new 10.5-inch A1 Carbine SBR.
This retro A1 Carbine SBR is an ideal pairing for anyone looking to run a suppressor on a high-mobility, exceptionally maneuverable defensive AR platform. This “old school is the new cool” configuration is the perfect SBR for those who value operational simplicity and no-fail performance as the base for their suppressed home defender.
With its lightweight, chrome moly 10.5-inch A-1 barrel assembly and CAR gas system, the A1 Carbine SBR with an attached suppressor (suppressor not included) is compact and easy to handle in close quarter environments.
The A1 Carbine SBR comes chambered in 5.56 NATO/223 Rem. and is built on RRA’s forged LAR-15M lower receiver and forged A1 carry handle upper. The barrel is fitted with a conventional F-style front sight/gas block and A1 flash hider (1/2-28 thread) and hosts a classic A-1 triangular handguard.
Two variants of the A1 Carbine SBR are offered: one with a multi-position M4-style stock and the other with a fixed entry stock. Both include RRA’s A1 grip and single-stage trigger.
If you’ve been considering purchasing an SBR for personal or home defense, the A1 Carbine SBR from Rock River is the ideal candidate and now is the perfect time to make your move.

The cost guidance is better than expected. If they deliver, the stock could rerate.
