The DPMS Firearms .308 Win 18" stainless steel M-Lok rifle is a purpose-built AR-platform rifle engineered for shooters who demand precision, reliability, and modularity in a mid-range caliber package. Built on a forged 7075-T6 aluminum receiver with hardcoat anodize finish, this rifle combines a proven mid-length gas system with a free-float M-Lok rail for consistent accuracy whether you're working steel at the range or hunting medium to large game.
The 18-inch 416R stainless steel barrel with a 1-in-10 twist is dimensioned and balanced for .308 Winchester, paired with a low-profile adjustable gas block that lets you fine-tune cycling based on ammunition and suppressor use. A nitrided gas tube resists the heat and corrosion that comes with serious use. The upper receiver features a PA10 flat-top with feed ramps and includes both a forward assist and dust cover—the fundamentals matter when reliability counts. The Toolcraft bolt carrier group uses 9310 steel with an extra-strength extractor spring and full nitride treatment, while the gas key is properly staked with grade 8 fasteners.
Down below, the lower receiver houses a Panther Polished Trigger for a clean break, a Magpul MOE Carbine Stock for adjustable fit, and a DPMS Custom Overmolded A2 Grip for confident control. The M-Lok free-float handguard delivers the rail real estate for optics, lights, and accessories without interference to barrel harmonics. A 20-round PMAG ships with the rifle. Whether you're setting up a precision rifle for distance work or a practical .308 for hunting and training, this DPMS platform delivers the accuracy, ergonomics, and modularity serious shooters expect.
