Help with SD700

Well, i guess I'm back again needing more help with this gun..


Okay so me and my buddies were out playin some airsoft today, when i started noticing that it was starting to get harder and harder to pull my trigger. Finally it got to the point where i could no longer take a good shot and pull my trigger. I decided to take the stock apart from the barrel and all the other components and take a look at it. I took it out of the stock and as soon as i did i messed with the trigger and it was working fine, it wasn't sticking and it was just as easy to pull as the day i got it. I figured maybe something was just in the way and it fell out when i took it apart, so i put it all back together. The first couple of shots worked great and i was totally stocked! Then about 10 minutes into the game i could tell that my trigger was becoming quite difficult again, so i proceeded to take it apart again and it started working great again after the stock was gone so i just put it back in and as soon as the stock was back on it stopped working again. I thought something might be wrong with the stock, but nothing looks out of place in it. My gun won't even shoot now, it is almost impossible to pull the trigger back.. Can someone help?


Thanks
