I don't recommend putting rubber bands internally to a maverick, I tried it and it bent the pin and snapped a part of the cocking piece where the pin rests when I tried to cock the gun. So dont try rubber banding.
Nice job, maybe I should try this on my maverick although a bit of plastic snapped of my cocking piece, and i think it got sucked up in the vaccum cleaner, thus preventing me from putting the metal pin that the spring goes around, so I think I will have to find some way of fixing it, I tried the hot glue thing but it didnt quite work it shot with less power than before I opened the gun very dissapointing.
