Daniel Defense M4A1 RIII, 5.56mm AR15 Semi-Automatic Rifle, FDE (02-191-04238-047)

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.

Just like the original, the M4A1 RIII is built around a 14.5 inch Cold Hammer Forged M4 Profile barrel with a permanently attached Daniel Defense Flash Suppressor. This rifle also comes with the ergonomic Daniel Defense Buttstock and Pistol Grip.
