To anyone who doesn't know, FPSUsername still continues building LEGO guns but posts it on Youtube. (This is not spam, FPSUsername told me to comment on all of his mocs telling everyone that he continues in youtube)

i think in your next build you should use the mech from Jack Streat's Jungle Carbine from his book, Lego Heavy Weapons. instead of the hammer's rubber bands being attatched to the barrel assembly, those rubber bands are attatched to the bolt assembly. EDIT: maybe use it on a assault rifle?
