Ok these are three of my guns that are currently out of commision.

kjw m700- Gas powered sniper. The standard mag has a problem holding gas and i don't think its just the o ring. Also, the high cap mag has a problem and i think its the oring. i fill it with gas and i hear a slow leak but when i shoot it you hear that it is very low on gas but no bb comes out.

well g3 sas- I think it has something to do with the wires where the battery connects at. The thing is i have two batteries but one battery might have been fried by my charger beings my charger melted to my wall somehow. it was an old charger but i dont know.

vsr-11- Bolt action sniper. Basically it still works but the spring thing that holds the clip in fell out and the screws that hold the barrel/trigger assembly fell out as well.

If there is anyone within 2 or 3 hours of me that would look at these guns for me and let me know what they think i would really appreciate it. I would be willing to drive to try and see what the problem is. I only have 1 working gun right now and its a gas powered aps type 96 sniper rifle. I want to get the others going to use them for loner guns to get more of my friends into airsoft. Thanks guys!
