Another rare piece of my collection. (NO TRADE) The original KTW is spring powered and only shoots 250 FPS Now it is converted with gas bolt, as you see you the pic, the bolt will hold green gas, red gas, black gas, possibly co2( might need change some O rings) It really shoots well, the longest distance that I have achieved with black gas and .48g bb combo for this rifle is 95 yards! Adjustable hop up is located on the top of outterbarrel Shooting video can be provided for serious buyer! With black gas it shoots 360 FPS with .48g Comes with 4 mags Gas conversion( already installed) An additional OEM R hoped bucking( has rhop Patch Integrated in the bucking, and is why it shoots well) Red dot is not included
