BILSON ARMS | A3FSSTB20R1 BA15FC | 6mm ARC | 18″

The BILSON ARMS A3FSSTB20R1 BA15FC is a semi-automatic rifle chambered in 6mm ARC with an 18″ threaded barrel and a 20+1 capacity. The rifle uses an aluminum receiver and ships with a B5 Bravo stock finished in black; it is configured for right-hand shooters and features an A2 birdcage muzzle. For an optic under $1,000 that complements this platform, consider the Vortex Viper PST Gen II 1-6×24 — it provides versatile short- to medium-range capability on an 18″ precision-oriented rifle. Typical applications include medium-range precision shooting and varmint or medium-game hunting where legal.
