The M4A1 RIII AR15 style firearm features a fully ambidextrous lower that allows both left- and right-handed shooters to operate the bolt catch, safety selector, and magazine release without having to move or remove their dominant hand from the rifle’s grip. Its GRIP-N-RIP Charging Handle is ambidextrous as well. We’ve taken the RIS II picatinny quad rail used on our M4A1 original and replaced it with a 12.5 inch RIS III rail featuring M-LOK attachment for lighter weight while still offering M203 grenade-launcher attachment. The M4A1 RIII is built around a 14.5 inch Cold Hammer Forged Government Profile barrel with a permanently attached Daniel Defense Flash Suppressor. This rifle also comes with the ergonomic Daniel Defense Buttstock and Pistol Grip. SERIOUS buyers ONLY! Buyers must have CCW legal ID in Florida. NO TRADE! Text Me ! 904-3twotwo-F0ur2- ZERO2
