DPMS AR10 A3 Upper Receiver


Completely assembled upper is ready for barrel installation and then attachment to a LR-308 Lower Receiver. Includes ejection port cover, forward assist and charging handle. Does not include bolt carrier assembly. Aluminum receiver has been T6 heat treated and hard coat anodized.


  • Extra-thick walled 6066 aluminum extrusion that has been T6 heat treated, hard coat anodized (Mil-A-8625A)
  • Completely assembled, ready for installation of barrel (not included)
  • Includes ejection port cover, forward assist and charging handle

NOTE: This is the new Low Profile LR-308 Upper Receiver that measures 1/8" thick from the top of the receiver rail to the charging handle cut-out. Railed handguards must be specifically sized for the low profile upper for the two top rail sections to match up, otherwise the handguard top rail will be proud of the upper's top rail.
