These guns DO NOT WORK. I’m too lazy to fix them and I have no interest in buying more parts to attempt to fix them again. Top gun is an Umarex Beretta ARX 160. It has a bad trigger and connector and likes to get stuck in full auto. It also likes to fire while on safe. Middle gun is an A&K ACR. It has a bad battery connector and won’t fire with the hand guard on. It fires fine when the hand guard is off. This is probably an easy fix. Bottom gun is a TM G36c. The hopup is broken and this gun is discontinued and there aren’t many hopups left for it.
