The Daniel Defense AR-15 MK18 Pistol Upper Receiver Assembly is produced from Mil-Spec 4150 Chrome-Moly Vanadium Steel and is Chrome Lined for durability and corrosion resistance. It is part of the daniel defense’s complete upper, faithful pursuit of the US Navy’s Mk18 Mod 1 platform. An actual 5.56×45 NATO chamber may use both commercial and higher pressure surplus mil-spec ammunition safely, and M4 feed ramps are included in the barrel extension and ar uppers to improve reliable feeding.The gas key is securely fastened to its mil-spec bolt carrier, and the bolt and carrier both pass a comprehensive Magnetic Particle Inspection (MPI) test for verified structural integrity. While aluminum regions are Type III Hard Coat Anodized, all steel parts have a solid Mil-Spec Phosphate coating for better corrosion resistance and longevity.This daniel defense stripped upper has a 9.5″ Flat Dark Earth RIS II Mk18 Quad-Rail Handguard that Free Floats the barrel for more significant accuracy potential and covers a pinned, low-profile gas block at the carbine gas port position. The A4 Flat-Top receiver of the RIS II creates a full-length, unbroken top rail surface that can support a shooter’s preferred optic and iron sight setup while leaving plenty of opportunity to add tactical accessories. The daniel defense 300 blackout upper comes with a charging handle assembly and a daniel defense 11 5 upper and is prepared to be dropped onto any registered SBR small pin lower receiver or handgun.
