The DDM4 V7 AR15 style firearm features M-LOK attachment technology with the Daniel Defense MFR 15.0 rail. Built around a Cold Hammer Forged 16 inch barrel the V7 has a DD improved Flash Suppressor to reduce flash signature. The mid-length gas system provides smooth and reliable cycling under any condition and reduces both perceived recoil and wear on moving parts. With the M-LOK attachment points that run along 7 positions and an uninterrupted 1913 Picatinny rail on top the V7 has plenty of room for the sights optics and accessories the user may require. The independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters. This rifle also comes with the ergonomic Daniel Defense Buttstock and Pistol Grip. – MATERIALS & CONSTRUCTION – LOWER RECEIVER: Mil-Spec with Enhanced Flared Magazine Well and Rear Receiver QD Swivel Attachment Point.
