ASG/KWA MP9 GBB - Why does my nozzle keep breaking?! (Airsoft) + a cheeky little full auto mag dump 

This is actually common on a lot of GBBs, all you have to check with any GBB is to just press the BB down and see if it has room to move down. Easy just to fill full and -1 The manual for the MP9 actually explained this, but I guess nobody reads it. (Mine is the KSC version, i'd assume KWA also has it)

If you want to lower the power and reinforce the internals, Wiitech is a good option since they are made of aluminum or steel. The parts to change are a) cqb nozzle b) chassis c) Part 153 (especially if you use burst a lot) d) Spring (optional) A warning: if you put the mouthpiece and chassis on, make sure the pins are well placed, since if it protrudes even submillimeters outwards, the replica will get stuck. I had to put loctite screw glue on mine so that the pin wouldn't move.

Hey, great video. Also where did you get those mags

Is kwa and asg the same company?
