I can't be bothered to make one either. I just really don't care for single shots and if I did really want to make one, I'd just stick with something similar to Killerk's pistol. This seems like overkill. First off, K'nex stocks can help you steady a gun if it's large enough but usually they aren't large enough until you, ironically, add a stock. Otherwise K'nex guns have very minimal recoil. Same case for a foregrip. It can help you steady the gun by having a place to put your second hand but by adding all the extra weight to put your hand somewhere, you've made a gun you can't steady with one hand as easily. A killerk pistol doesn't need a stock or foregrip. You can aim it with one hand just fine. Well there's my wall I felt like putting up for no reason.
