DPMS DP51655142603 | .308 Win | 18″ M-LOK | 20rd

The DPMS DP51655142603 is an AR-10 style rifle built around a dimpled, nitride-coated 18″ 4150 Chrome Moly Vanadium barrel chambered in .308 Winchester with a 1:10″ twist and a mid-length gas system. The upper assembly uses a 15″ DPMS M-LOK free-float rail with a low-profile, 3-position adjustable gas block and an A2-style muzzle device; the platform pairs a forged 7075-T6 aluminum upper and lower with a B5 Systems Bravo telescoping stock and a Panther over-molded grip. For optics, the Vortex Strike Eagle 1-6×24 is a suitable sub-$1000 option that provides fast target acquisition at close range and usable magnification for precision work.
