Stock JG M4-CQB Mod suggestions
 

Ok, So i've recently bought a new JG m4-CQB, and i keep hearing that JG Mechboxes should be re-shimmed, and greased. Anyone care to explain why and/how? And please use or explain terms, Im not so adept with the airsoft jargon.


Also I'd like some suggestions on what else I should do to keep my m4 in working order. ( ie swapping out parts that are rubber or what not. Assuming there are pieces to be swapped )

EVERY mechbox could use a re shimming, that's just how it is. Doesn't mean it'll break or anything without one but it's always a good call. JG's are notorious for having WAY to much grease. It even comes out the nozzle sometimes and gums up your barrel and hop-up. Other then that it should last you quite a while.
