The blue anodized Mega Arms billet 7075-T651 receivers anchor this FN 15 Competition build, with an ambidextrous bolt-catch release integrated into the lower. Controls are upgraded for efficiency, including a Radian 45/90-degree ambidextrous safety selector and a Magpul BAD lever for enhanced bolt manipulation.
The 18" barrel is 4140 steel, cold hammer-forged, chrome-lined, and threaded 1/2x28 with a SureFire ProComp 5.56 muzzle brake. A rifle-length gas system, PRI low-profile gas block, and H2 buffer are paired for smooth cycling. FN’s factory literature cites approximately 1.5 MOA accuracy with match ammunition.
A Mega Arms 15" free-float M-LOK aluminum handguard with a continuous 15.0" top rail provides ample mounting real estate while keeping the barrel free-floated. The nickel-boron coated bolt carrier is laser-marked "Competition."
The fire control is a Timney Competition single-stage trigger with a gold-anodized shoe for a crisp, consistent break. Furniture includes a black Magpul CTR 6-position adjustable stock and a black synthetic pistol grip with molded texturing. The package is topped with a Leupold Mark AR 1.5–4x20 scope installed in an Aero Precision cantilever mount for dependable optical clarity and positioning.
