Ok, i have a sft shocker its 1 of 1 apparently and has nice milling, however has a problem in the fact when gassed up and shot the bolt stays forward and gas pours out the barrel. Ive done so much to fix previous issues this gun has had, is it best to keep trying to fix it and put money into getting it to work, or is there any market on here for selling broken guns as projects/parts? Cheers, as this post may suggest im new to this part of the forum.
