The DPMS DP51655131212 Quad-Rail Upper is a complete 5.56 NATO upper built around a 10.5" 4150V chrome moly vanadium barrel that is nitride treated for added durability. The 1:7 twist is paired with M4 feed ramps, which are there for improved feeding. A low-profile gas block and an A2 flash hider finish off the barrel. DPMS assembles each upper to order and test fires it, so it arrives ready to install on a standard AR-15 lower.
The 9" Panther quad-rail handguard carries exclusive Panther markings and gives you rail space for the accessories you want to mount. The forged 7075-T6 A3 upper receiver is hard coat anodized black for durability and is made in the USA. Included are a bolt carrier group, charging handle, forward assist and dust cover, so the upper arrives assembled with its core parts. The bolt is made of Carpenter 158 steel.
