Gun spanked in

[hooobit]

I took apart my king arms S&W15 to replace the spring, its back together now but doesn't fire. The motor will run but no rounds fired and it only fires on full auto now, the selector doesn't work on semi-auto. Help please.

 

P.s. this is my first aeg and ive never stripped one before

[hooobit]

Oh man i hated guard duty. I stuggled with my v2 gearbox. It might be that you have put the little gears on the outside of the gear box on wrong as i did that first time to.
