The Bilson Arms P7UFSFG10R1 BA-15FCP .338 ARC Upper Receiver pairs a 12.50" threaded barrel with a distinctive Flat Dark Earth and Sniper Green Cerakote finish. Built on a billet aluminum receiver with a full-length Picatinny rail and free-floating M-LOK handguard, this forward-charging upper is designed to drop onto a standard AR-15 lower while delivering big-bore .338 ARC performance. A 1:8 twist 416R stainless steel barrel and A2 birdcage flash hider round out a compact, suppressor-ready package.

This assembled upper is ideal for shooters wanting a versatile AR pistol or SBR build for range use, training, or hunting where the .338 ARC cartridge’s subsonic and supersonic capabilities can shine. The innovative non-reciprocating forward charging system lets you cycle the action without breaking your cheek weld, supporting faster follow-up shots and more comfortable handling. Thoughtful engineering and in-house manufacturing reflect Bilson Arms’ focus on precision, reliability, and modern innovation in AR-platform uppers.
