Product Description The DPMS Panther Arms DP-10 complete upper is built for shooters who want a durable, tunable .308 Winchester setup with modern mounting flexibility. This assembly features an 18 inch nitride-finished barrel with a mid-length gas system, paired with a 15 inch free-float M-LOK handguard with partial Picatinny rail sections and anti-slip, anti-rotation features. A low-profile, click-switch adjustable gas block helps you fine tune function to your load and conditions, while the black nitride gas tube improves heat and corrosion resistance. This upper ships complete with a Toolcraft bolt carrier group and a 7075-T6 charging handle, making it a ready-to-run top end for compatible DP-10 pattern builds.
