I bought a Marui SG1 from a board member a while back (can't find the post for it anymore) that had been upgraded and I can't remember what the upgrades were. I used it a few times and it worked great but some time ago it stopped firing right and made nasty grinding sounds. I stopped using it after the grinding started to try and minimize any damage and got busy so it's been sitting in a closet for a long time. I finally got around to taking it apart today and found the bevel gear has a partially broken tooth, badly enough so the gears just bind at that point. Everything else looks good other than it needs grease. My question is if there is any way to get a new gear without having to get a whole set and a new spring to make sure it all matches. I know the spring was upgraded, but don't know of any way to find out what the spring actually is so I don't want to get a gear/gearset that won't do the job.

I've had these goggles for about a year now for airsofting and figured I'd share this with people. I know goggles are probably (to me they are) the most important piece of gear to an airsofter. It's tough to have a fun game when you've lost an eye and it tends to be a tad inconvenient afterwards. And so I got some Uvex goggles for my first game last year with my Camelback from the same site.

They come with antifog, antiscratch and antistatic coating, though mine have some scratches they don't cause any problems and the goggles do occasionally fog up on the top half, but never too bad. They are nice sized and lightweight so don't interfere with peripheral vision at all, a few times I've forgotten I'm wearing them. One downside to that is that they are a bit bulky on the side and so it's tougher to use scopes and such because it's hard to get your eye that close, but I figure that's a downside to goggles anyway. They also meet/exceed (based on which site you look at) ANSI Z87.1-1989 and CSA Z94.3-1992. I can attest that they can take some BB hits. Mine have been thwacked directly in front of my eye a few times with BBs at decent strength and no sign of any damage. The strap that comes with them is a thin rubber one, it's held up without any problem, but I didn't want them falling off by accident so I jury-rigged a valcro strap to ensure they stay on tight. The only main complaint I have is that the seal around the face is rubber, nice for cleaning but it occasionally gets a bit irritating near the end of the game, solved by taking them off during an official break in the game.

For those of you looking for some decent goggles they're here for $10.00
