DPMS DPM4 AR-15 Rifle 5.56 NATO 16″ Threaded Barrel M-LOK Free-Float Handguard M4 Stock – 30rd

The DPMS DPM4 AR-15 delivers mil-spec performance and modern features at a price that’s hard to beat. Built on a forged 7075-T6 aluminum upper and lower receiver with a hardcoat anodized finish, this carbine is engineered to MIL-SPEC standards from the ground up.

At its core is a 16″ chrome-moly vanadium (4150V CMV) steel barrel chambered in 5.56 NATO, finished with a nitride coating for enhanced corrosion and wear resistance. The M4-profile barrel features a 1:7″ twist rate, carbine-length gas system, low-profile .750″ gas block, and is capped with an A2 flash hider. A 13.5″ DPMS M-LOK free-float handguard surrounds the barrel, providing a clean, modular platform for accessories while improving heat management and accuracy potential.

The full-auto profile bolt carrier group is built to exacting mil-spec standards — featuring a shot-peened Carpenter 158 steel bolt with mag phosphate coating, an 8620 steel M-16 profile carrier, a gas key hardened to USGI specifications, secured with Grade 8 screws and staked per mil-spec.

The lower is equally dialed in: forged 7075-T6 aluminum marked “MULTI” for caliber flexibility, fitted with a mil-spec fire control group, DPMS A2 grip, aluminum trigger guard, and a 6-position collapsible M4 carbine stock on a mil-spec diameter 7075-T6 buffer tube. Includes one 30-round magazine where permitted by law.
