Reviving an older post, do you have any tutorials on how you did this? Barrel swap seems fairly simple, but what about converting to bottle gun? Looks like you did some stock trimming, but other than that, how much did you have to modify without just bolting on new parts, if if you don’t mind saying how much it. OST you overall?
