This LR-308 upper receiver is the receiver only and does not include any other parts for assembly. Constructed of thick walled 6066-T6 aircraft aluminum and with a flat-top that will accept optics or a carry handle. Matte black finish.
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.
