The LBE Unlimited Upper Receiver (brand part no. ARUPPER) is a 5.56x45mm NATO AR-15 upper forged from 7075-T6 aluminum and finished in black, with the forward assist and ejection port cover assembly already installed. LBE Unlimited machines the interior with a dry film lube coating to reduce friction and ease bolt carrier group cycling from the first round fired. Since this is a semi-complete upper, it still needs a charging handle, barrel, handguard, gas block, muzzle device, gas tube, and bolt carrier group to finish out the build.
