DPMS DP10 Complete Upper Features The Dpms Panther Arms DP10 upper is machined from forged 7075-T6 aluminum and finished in black hardcoat anodizing giving the receiver corrosion resistance and long-term durability under hard use. Its dimpled black nitride treated .308 Win barrel carries a 1:10 twist rate matched to a mid-length gas system which meters gas pressure more gradually than a carbine-length system for smoother cycling and reduced felt recoil. A 3-position adjustable click-switch gas block lets the shooter fine tune gas flow to match different ammunition loads or a suppressor while the black nitride gas tube resists fouling and corrosion over repeated firing cycles. An A2-style muzzle device caps the barrel and helps control muzzle rise during rapid strings of fire. The 15 Panther Arms M-LOK free-float handguard keeps the barrel from contacting the rail under pressure which helps preserve accuracy as the barrel heats up during extended range sessions. A partial Picatinny top rail provides a continuous mounting surface for optics while the M-LOK slots along the sides and bottom accept lights foregrips bipods and other accessories without the bulk of a quad rail. The included Toolcraft bolt carrier group pairs a 9310 steel bolt with extra-power extractor springs for more reliable extraction and the nitride treated 8620 carrier resists wear across thousands of rounds. A 7075-T6 aluminum charging handle rounds out the assembly giving shooters a complete drop-in .308 upper for hunting precision rifle competition and general purpose AR-10 builds.
