Okay well as the title says my JG BAR 10 is now "slam firing". I will go to pull back the bolt to load it and before it would stop like normal, but when you'd go to push it forward it would slam forward and I couldn't shoot. So obviously I was bummed. I've had the gun a few months, and I've put a few hundred rounds through it in case that's important.
I tried doing research on what could be wrong and came to the conclusion that it was the sears maybe being worn down. However I decided to take it to that Gearbox store and see if they could help. Well two and a half weeks later they said for sure it was the piston thats worn down. Now in no way am I saying these guys are bad, in fact I would recommend them wholeheartedly. They're great and their customer service in my experiences are great. I drive from across phoenix just to go there. That being said, I ordered a brand new high pressure piston and its still doing it. This time when I pull it back it just shoots forward.

So please any ideas what could be wrong? I'd rather not spend money that I don't need to again. Although since I now have a high pressure piston and I might need to get new sears, I might just get a higher spring too  

Thanks for your help

Okay so here's my problem

I FINALLY got my gun in the mail, and was completely excited. I assembled everything and was really excited. So I go to put the sniper mount on the top and it wasnt working. I coulf get one screw put in, but no matter what I tried I couldnt get the second one in. So after an hour I realized the holes used for screwing on the rail system weren't the correct distance apart!

Has anyone else had this problem, or am I just a lucky  guy? and I would imagine there's not much I can do, so i should just exchange it.

Okay so here's what's happening.

I just got a Well R8 G3 SAS in the mail yesterday. Everything was working great. Then the magazine got jammed from crappy bbs so I worked on that. Then my brother set the battery in the charger for the night and left it until morning. Now when he goes to shoot it, it makes no sound whatsoever. No clicking or anything. So I'm guessing he messed up the battery because we didnt shoot it a ton and he charged it for around 10 hours. Or the fuse is messed up.

What do you guys think it could be?

Also I took it to an airsoft store and he agreed it might be a fuse, and that he'd check if I brought it to him. So I'm either gonna do that or return it to the site. Although I'd rather bring it to the guy if it is just one of those two problems.
