ok couple of things with mine is it doesnt slide well. i know it needs lube. since its full metal would gun lube work?
also both my mags are broken (for extra let me know) both have the same problem. i didnt lock my safe and my stonner roommates broke it on me.
its the bit at the top and i dont knwo where to get new peices. one doesnt hold gas,,, well both dont any more and both will noto hold bbs. one shoots them out. and the other wont let go of them inside the gun when it loads when cocking.
advice?
