Daniel Defense DDM4 V7 Pro 5.56 NATO Semi-Auto Rifle, 18" Heavy Barrel, Custom Magpul Stock
The DDM4 V7 Pro is Daniel Defense’s competition-tuned version of the proven AR-15 platform. This rifle stands out with its 18-inch cold-hammer-forged S2W heavy barrel, factory-pinned and welded Muzzle Climb Mitigator, and a match-grade Geissele SD-3G trigger. A Magpul six-position stock replaces the factory unit, giving the shooter adjustable length-of-pull while keeping overall weight low. Built on hard-coat anodized 7075-T6 receivers and paired with a 15-inch free-float M-LOK handguard, this rifle arrives ready for serious range work or 3-Gun competition.

Designed around a rifle-length gas system, the V7 Pro delivers smooth recoil impulse and reliable cycling with standard 5.56 NATO loads. The chrome-lined CMV barrel is chambered in 5.56 NATO, buttoned into a 1/2-28 threaded muzzle, and finished off with the factory Muzzle Climb Mitigator that is permanently pinned and welded for compliance.
The 15-inch Daniel Defense MFR 15.0 M free-float handguard provides extensive M-LOK slots, a continuous top rail, and ample clearance for low-profile gas blocks. Its slim profile keeps the rifle agile while maintaining rigidity for consistent accuracy.
Controls are competition-focused. The Geissele SD-3G single-stage trigger offers a short, crisp break, while the ambidextrous GRIP-N-RIP charging handle features extended latches for fast manipulation from either side. An enhanced flared magazine well speeds reloads, and the aluminum receivers wear a durable Type III hard-coat anodized black finish.
Rounding out the package, the Magpul six-position stock lets shooters dial in a 12.5-inch length of pull, contributing to a full-size feel that can still adapt to armor, clothing layers, or individual preference.
