    I bought a kwa mp9 from the bone yard from my local store. The problem was the mag was stuck and it would not shoot. I fixed those problems now a new one occurred. The problem is that on semi it shoots every other bb and on full auto it shoots like 6 bbs then I have to prime the gun again. Any tips????

    Sounds like its only a magazine problem. Clean and lubricate your magazine and see if that helps.

    Lubricate the insides of it really good with 100% silicone (15 wt. preferred). Lubricate the feeding nozzle especially. Now move to the mag. When you load it, are you stacking the BBs in a zigzag (double stack)? If not, that's the cause. If you are, try lubing the valves good to get a better seal and then make sure the magazine is seated correctly in the Magwell. Also, you may need to make your valves open up more for gas (hi flow mod basically.).
