The gun worked for a few hours a day, but then it would start chopping bbs. I tried a number of things: I lubed all my mags, filled them up, emptied them and repeated the process. Then I took apart the cylinder and did the air nozzle loctite mod. Still no luck. What's really a bummer is that I've seen what this rifle can do! I had my friend run back and forth at 150 ft and I was easily able to hit him 10/10 times! I've used a number of bbs: airsplat .28s (oddly enough, these are the best bbs for my Systema Revolution, so I figured I'd give it a shot), Echo 1 .25s, hailstorm .28s, TSD .23s, TSD .26s, Elite Force (Umarex) .25s, and G&G .2s. The G&Gs were the ones I used for a while, and they worked beautifully for about 2 mags. I've ordered some airsoft elite .25s in hopes that this solves the chopping issue.
After doing everything listed above, and cleaning the barrel extensively, checking the alignment of the cylinder and hopup, and just making sure that everything looks like it's fitting together nicely, the gun is still not working . Right now, the G&G .2s aren't chopping, but they're also not firing more than 25 feet. They seem like they don't have much power behind them, but I see no reason for that. Does anyone have any ideas? Thanks!
