I think I've heard it said that if you play Airsoft, your gun will break at some point. Maybe no one said it; maybe it's too obvious. Anyway ...
I've been experimenting with optics for the G&G L85 carbine I bought at the end of January. I'd found and purchased a replica SUSAT for it online (no one had that weird stuff on-shelf locally). The SUSAT worked great. I used it on Saturday at The Swamp, where my chronograph readings were disturbingly low (320 FPS/0.20g) compared to spec info (370-400 FPS/0.20g). This got my spider sense tingling, but like a teen with a suspect car, I kept on keeping on.
Recently, I found a Madbull A3 railed fore end for it, which gives me the option of running forward-mounted optics. Tried an EOTech -- made the gun too front heavy, so I grabbed a SIG RDS on an AR-height riser. It looked OK on there and the weight distribution was good; I decided to sight it in.
Inserted a mag, took it outside, aimed at the plastic bowling ball in the back yard, and pulled the trigger. The gun made a whirring noise and vomited BBs onto the deck. I reseated the mag, flipped the selector up and back down, and pulled the trigger again. More whirring, more BB vomit.
Called Extreme Velocity to check whether I'm still within G&G's warranty period (I am) and arranged to get it in for a "looking-at" tomorrow. I should be bummed, maybe, I dunno. I'm kind of glad I've been using it and enjoying it enough to get to this point. Use = love, right?
And so begins the journey of repair, possible upgrades, etc.
Shameless plug: the gang at EV have been quite helpful to this particular noob.
