DD MK18 RIII 10.3”

Brought this brand new and put a new inner barrel and bucking in it which voided warranty when the gearbox packed up, has had a new cyma gearbox in. Have tested it with a few shots but I brought a new RIF whilst this was being repaired so isn’t needed the bolt release no longer works, body work is a bit rough and is missing a stock. Any more info or pictures please ask. Collection only. TIA
