Buy Daniel Defense M4A1 MilSpec Online | Western Sport — DD Master Dealer
If you want the closest thing to what U.S. Army Special Forces carry into combat, the Daniel Defense M4A1 MilSpec is it. Daniel Defense has been a primary supplier of M4A1 upper receiver groups to the U.S. military for years, and this civilian-legal rifle is built on the same manufacturing line to the same tolerances.
The M4A1 MilSpec features a 14.5-inch cold hammer-forged, chrome-lined barrel finished with a permanently pinned and welded Daniel Defense Flash Hider to achieve a legal 16-inch overall barrel length. The Daniel Defense RIS II free-float rail system — issued to Special Operations units worldwide — provides incomparable rigidity and a consistent zero for your optic.
No shortcuts. No compromises. The M4A1 MilSpec is machined, assembled, and tested in Black Creek, Georgia. It features MilSpec-anodized upper and lower receivers, a MilSpec bolt carrier group, and the legendary Daniel Defense reliability that has proven itself in the harshest environments on earth.
