This video tests the long-range capabilities of a Bear Creek Arsenal (BCA) 16" 5.56 carbine upper receiver mounted on an Anderson lower. The test focuses on hitting a 20-inch gong at 300 and 400 yards using IMI 5.56 M193 ammunition. The presenter emphasizes that the goal is to hit the plate, not achieve tight groups, especially given the budget components and moderate wind conditions.
This video provides an accuracy test of a Bear Creek Arsenal .22 WMR upper receiver at 100 yards, evaluating three different ammunition types: CCI Maxi Mag 40gr HP, Federal 50gr, and Hornady V-Max 30gr. The test highlights potential accuracy improvements with a better lower receiver and rest, but indicates the BCA upper is not overly ammo-picky and performs decently across tested loads.
