The Bilson Arms A2FCS4920R1 BA15FC .300 Blackout rifle brings Bilson’s forward-charging AR-15 concept to a 16-inch platform finished in Sniper Green and Gray. Built on precision-machined billet aluminum receivers with a free-floating M-LOK and Picatinny handguard, it is designed to minimize upper–lower receiver movement and deliver consistent accuracy. A 4150/4151 CrMoV steel threaded barrel capped with an A2 birdcage muzzle device, combined with B5 Systems buttstock and pistol grip, creates a balanced, modern semi-auto rifle ready for serious range work.

This BA-15FC configuration is chambered in .300 AAC Blackout with a 16-inch barrel and 20+1 capacity, offering smooth handling and familiar AR-15 ergonomics for training, general range use, or recreational shooting. The rifle ships without sights, allowing shooters to choose their preferred optic or iron sight setup. Backed by Bilson Arms’ 1 MOA or better accuracy guarantee and manufactured in-house from 100% American-made parts, it reflects the brand’s focus on precision machining and thoughtful design.
