Daniel Defense M4A1 RIII 5.56 14.5", Black - 02-191-10613-047

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. 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.Features:BARREL: Chrome Moly Vanadium Steel, Cold Hammer Forged, 1:7 Twist, 14.5" Government Profile, Chrome Lined, Mil-Spec Heavy Phosphate Coated, and HP/MPI TestedGAS SYSTEM: Pinned Low Profile Gas Block CNC Machined of 4140 Hardened Steel with Mil-Spec Heavy Phosphate Coating, Mid-length, Direct ImpingementMUZZLE DEVICE: Pinned and Welded Daniel Defense Flash Suppressor, Extended, 17-4 PH Stainless Steel, Salt Bath Nitride FinishedBOLT CARRIER GROUP: M16 Profile, Mil-Spec MP Tested, Chrome Lined, Properly Staked Gas KeyBUFFER: H BufferSIGHTS: Sold SeparatelyHANDGUARD: Daniel Defense RIS III 12.5, Patented, 6-Bolt Bolt-Up System, Flat Dark Earth CNC Machined of 6061-T6 AluminumCHARGING HANDLE: GRIP-N-RIP Charging Handle, Body CNC Machined of 7075-T6 Aluminum, Handles & Latch CNC Machined of 6061-T6 Aluminum, Heavy Duty Stainless Steel Roll Pins, Type III Hard Coat AnodizedRECEIVER EXTENSION: 6 Position Mil-Spec 7075-T6 AluminumBUTTSTOCK: Daniel Defense Buttstock, Glass Filled Polymer with Soft Touch OvermoldingUPPER RECEIVER: Mil-Spec with Indexing Marks and M4 Feed Ramps.
