    I'd honestly just try fixing your compression as best you can, new bucking, and a tightbore barrel [6.01 preferably].

    How bad is the stock compression on CYMA aeps? I prob won't be getting a 6.01 barrel unless there is some cheap option available.

    It can be bad. I found most of my air leak was from the piston head. It is a 2 piece piston head. So glue it together with something that will seal the gap between the 2 parts.

    The stock air seal in my CYMA USP was surprisingly good, so I guess I won the "ACM lottery" in that regard.

    Tightbore barrel will make a big difference. You definitely don't want to go with anything wider than 6.01 though.

    Has anybody done any testing with the drop in aep lipo batteries vs the modded lipo batteries? I've seen some people say they're better than what you can do yourself, but if I'm seeing things properly they typically have a lot less wiggle room and then you can't put in a mosfet there either.

    I'd like to share a design of mine, a "barrel brace" for the USP, in case someone finds it useful/interesting:
    https://www.thingiverse.com/thing:4859372

    It's basically a clamp to hold the barrel firmly towards the nozzle/hop, theoretically helping make the nozzle/bucking seal better and/or more consistent. Possible overengineering, but I reckon it can help in some cases (it did in mine).
