This rifle is built for performance and reliability, featuring the robust M4E1 Pro lower receiver and M4E1 threaded upper receiver, both anodized black to ensure superior durability and resistance to corrosion. The 16 inches cold hammer-forged barrel is chrome-lined for enhanced longevity, delivering exceptional performance with every shot. Paired with a mid-length gas system and pinned low-profile gas block, this rifle offers smooth cycling and reduced recoil, making it highly efficient in rapid-fire situations. The chrome-lined, phosphate-finished M16 cut bolt carrier group (BCG) is equipped with a C158 tool steel bolt assembly that has been rigorously high-pressure tested (HPT) and magnetic particle inspected (MPI) to guarantee maximum reliability. For added versatility, the BREACH ambidextrous charging handle and Pro ambidextrous safety make the rifle ergonomically suitable for both right and left-handed shooters, ensuring seamless operation and control.
