Mk18 Mod1 Upper Receiver Group, Colt, DD, stripped

This is a mil-spec Mk18 upper receiver group, with rail, without a BCG, charging handle, rail covers or muzzle device.

Some of our LE customers requested a stripped version, to use with their own suppressor adapter and matching bolt.  Assembled by our good friends at Potomac Armory, this upper receiver group contains:

  • Colt mil-spec M4 upper receiver, with hardware (dust cover, forward assist)
  • Daniel Defense 10.3" Mk18 chrome-lined barrel
  • Mil-Spec Mk12 gas block, either Daniel Defense or Badger Ordnance (based upon supply, and not a buyer's choice)
  • Daniel Defense Mk18 RIS-II rail in FDE with mounting hardware and barrel nut.
  • Carbine gas tube, installed.
