I figured it out. For anyone whom stumbles across this thread in the future this was my issue and what solved it: I had put a perun v2 mosfet and 13:1 gears in the gearbox. Compression was good, as was everything else. After trying loads of hop rubbers and other things, I found only pulling on the mag towards me would fire the rif. Turns out, the 13:1 gears were too fast to pull the nozzle far enough back in order for the mag to correctly feed bbs. I swapped the gears back to the stock 18:1 and put it back together. Works perfect. Sometimes too fast gears are the problem. There might be other ways to solve this, but I can't be bothered. I'm happy with the perun upgrade.

Yes there is Yes

Hey, Hope this is the right place to post. I'm at my wits end with this. So just to be clear, I've installed perun v2's in three of my rifs, with gears, pistons upgrades etc. All have shot fine, they are all metal. I've just upgraded a gearbox of a valken asl with a polymor body, put it all back together and its not firing properly. Now here's the weird thing, if I pull the mag towards me when holding the gun, essentially bending it slightly, it fires. If I take the small spring off the hop and let it sit in against the upper barrel, and not pushed back snug against the nozzle, it fires. But with everything where it should be, I get a sound like it's muffled. Could this be an issue with the nozzle? It's the first time I've left a nozzle stock and not replaced it. I've tried 4 different hop rubbers, 3 different barrels. I've tried ZCI hop up Chambers, I've tried the stock chamber and nothing seems to work apart from when I bend the rif. It's not an alignment issue as I've tried aligning it up and down. Please help!

I think this is totally right! It is a KWA rifle as well!! Thank you so much, you are a star and spot on.

Hi all, Just a quick one as I really can't figure this out. So today on site, while my AEG was being chrono'd, it came out too hot at 1.3J (my site limit is 1.14J. It had an m120 spring inside, so I quickly changed the Spring to a 110. When I came back, there was a significant power drop to 0.5J. I couldn't work it out at all and decided to use my back up rifle. When I got home I had a look on my own chrono and got the same result, yet when I swapped the batteries over (from 11.1v to 7.4v) the power jumped back up to 1.1J. The batteries have the same ampage and C output, so I am stumped. Any ideas why the power drop using 11.1v? Both batteries were fully charged.
