The Battle Arms Development Enhanced Bolt Catch transforms AR15/M16 reliability with precision-machined 8620 steel construction and black phosphate finish. This upgraded component eliminates common bolt hold-open failures while maintaining full mil-spec compatibility. Enhanced geometry provides consistent engagement across various ammunition weights and buffer configurations.
What Makes This Different
Unlike standard bolt catches that rely on basic stamped construction, this enhanced version features CNC-machined 8620 steel with optimized contact surfaces. The redesigned paddle geometry increases surface area by 40% compared to mil-spec catches, reducing wear on the bolt carrier. Black phosphate coating provides superior corrosion resistance while maintaining the precise tolerances required for reliable function.Key Features
