Ok so i got this lm4 a few months back, and every so often i feel the need to clean and lubricate my gun.....how ever last time, I took it into the shop, and they lubricated the bolt catch.....Im not sure if this was good for my gun because now, when i fire, the bolt will not lock back...How can i fix this problem?

Do the bolt catch mod and keep it clean.
