Hello all interested readers. I just now finally got my stamp and approval from "those guys" and wanted to try out my new M2 Carbine. So I loaded up my mag with .30 cal ammo that has worked flawlessly in my M1 Carbine and unfortunately, it didn't work as planned. Here's the trouble. As mentioned in the title, I can't get the rifle to fire on full auto more than 2 shots at a time. I have to recharge the handle after it shoots the 2 rounds to cycle another round into the chamber. It'll fire another 2 rounds, then I have to do the same thing over. Before shooting, I cleaned and lubed the entire rifle. It does work perfect on semi. However I didn't buy another M1, I bought, and waited a year for the M2. Please help and thanks!
