First off no one that has no experience and wants to sound smart don’t post your ideas hear. Experienced ideas only.
1st Question:
I got a Red Star AK-74u and want to put in my type of internals, but I can get the thing apart. The cap that goes over the fire selector switch is on good. I don’t want to harm the gun but I want inside.
2nd Question:
I got a CA/E1 G36c with a mag feeding problem. Gun works good but I cant get a bb into the wepon, and before you ask the mags are all good.
