The DDM4 V7P AR15 style pistol pairs a 10.3 inch barrel and the MFR 9.0 M-LOK rail for fast handling, accuracy, and reliability while also providing compatibility with a wide variety of muzzle devices and sound suppressors. The V7P is classified as a pistol, not a short-barreled rifle, so it does not require ATF approval and a tax stamp. It features M-LOK attachment technology and comes equipped with the SB Tactical SBA3 Pistol Stabilizing Brace with 5 positions of adjustability and integral, ambidextrous QD swivel attachment point. The independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters. This pistol comes equipped with the ergonomic Daniel Defense Pistol Grip with an integral trigger guard and soft touch overmolding.
