Ok so my friend in Kuwait bought a snow wolf 50 cal clone.

Since then he has seen the light, but we are trying to do some upgrades to the damn thing. His original cost was about 450KD so we are despreatly trying to get this thing to sing. I ended up buying a matrix 8mm reniforced gearbox completely done, but I am having a issue. The BBs wont feed. Basically what is happening is the air nozel isn't withdrawing far enough. In the attempts to fix the nozel (dremel it down) we found that the force of the m160 spring vs bb was fractureing the nozel. It did feed though so here is the issue. We replaced the nozel same issue, and I need to figure out either a nozel replacement idea, or other sound suggestion in fixing this.
For those of you who havent been to kuwait yeah 450KD is a crap ton of money..... he didn't get taken as much as the crap you have to go through as a Kuwaiti to get anything in is rediculious.
