I got my SD700 from Buyairsoft.com about a month and a half ago and i was sufficiently pleased with it and had had a few skirmish's until the other day when i picked it up and tried to work the bolt. Pulling it back was no problem but when i tried to push it forward there was a little strain then it slammed forward firing the gun. i tried a few times after that and no change. Long before i got the gun i had heard of someone who had the same problem but i don't remember if they had fixed it and i cant find where it was anyway so can anyone else help me with this problem? having to buy replacement parts isn't a problem id just like to be able to use it again.

EDIT: so I've done some more research and the term is called "slam firing" i also figured out that its the trigger sear and the piston sear. the only replacement parts i could find were for the Tokyo Marui vsr10 so I'm assuming they'll fit but will that be the end of the problem or even with upgraded parts does it have a chance of happening again?
