Daniel Defense DDM4 MK18 Pistol, 5.56 NATO, 10.3-Inch, SBA3 Brace

The Daniel Defense DDM4 MK18 (Daniel Defense part no. 0208806030067) is inspired by the original MK18, a configuration that has been extremely popular within law enforcement and special operations communities. This firearm is classified as a pistol, not a short-barreled rifle, so it ships to you without the ATF approval and tax stamp that NFA-regulated items require. A 10.3-inch black threaded barrel with a 1:7 twist rate pairs with a black hard-coat anodized aluminum Picatinny rail receiver, and the SB Tactical SBA3 brace ships installed for a stable shooting platform. Ambidextrous controls and a black overmolded grip round out an ergonomic package built to the same standard as Daniel Defense‘s duty rifles.
