Shop the M4 Pro AI Tactical Black/Bronze at BattleHawk Armory. 18.5-inch Barrel and 12 Gauge Chambering The barrel measures 18.5 inches, making barrel length a clear purchase specification for this 12 gauge configuration. Match ammunition to the firearm markings and instructions, and verify accessory fit to the exact shotgun. Black/Bronze Finish The black exterior is contrasted with bronze details. That two-tone appearance distinguishes the finish without implying that bronze is the receiver material or that a particular coating process has been applied. Exact-Model Compatibility Confirm the appropriate host interface before selecting a mount or other accessory. Appearance, color and a shared M4 name are not sufficient evidence of parts interchangeability.
