The Ursid Hybrid Bear BCA AR-15 Complete Upper Assembly has a 16" m4 contour barrel made out of 4150 chrome moly vanadium steel with a parkerized finish, a 1:8 twist rate and a carbine length gas system. The build includes a 15" lightweight keymod rail, an M4 flat top forged upper receiver with forward assist, a proprietary bolt carrier group, birdcage flash hider and a charging handle. It is chambered in .223 Wylde and machined with M4 feed ramps in the barrel extension.
All Finished Barrels go through a 100% Inspection Process.
Inspections Equipment includes CMMs and Air Gauges for the Bores.
BCA's expectations is that our Barrels, 16 inch or longer, will hold a 1.000" MOA at 100 yards with appropriate ammo and shooting techniques.
BCA DOES NOT recommend using steel cased ammo in our Assemblies or Rifles.
