hi all. i thought i try my hand again at making something else. so i present to you my mini crossbow pistol: overall length is about 9 3/4 in. its a smaller pistol. much smaller than my folding slingshot crossbow. its using a roller set up. those are on there temporarily to see if everything is working correctly. the entire trigger mechanism is sealed. sorry guys, this trigger is spring powered instead of rubberband powered. for this one im going to try to use the 6.5 inch crossbow bolts meant for the 50 lbs. crossbow pistols. im still working on it also, but its at the point that its recognizable as a crossbow pistol. let me know if i need any room for improvements.
