Used parts And screws for cheap prices! The parts inside the red box are for a GBB WE SCAR L (see second picture or Boneyard lot sale) DM me for prices. These parts are cheap and small so I would like to keep the chatting to a minimum. 😊 -The Long black rail is a 10in Larue Tactical RIS. It has a bent mounting ring but can still mount with a little force.
