Hey guys,
some of you claim that KV does not perform well OOTB. Since mine was always laser accurate after I made some upgrades to it, here’s the list of things I’ve done:
1. Installed KWA LM4 low power floating valve, this keeps the gun at 1.14J on GG (depends on the gas and temp of course) and also saves gas.
2. Removed heavy recoil kit. Man, this thing is annoying, slows down the recoil and uses a lot of gas.
3. installed ra-tech/maple leaf evo II 6.01 barrel and metal hop up chamber. Paired with a dedicated maple leaf blue bucking can hop any BB weight.
4. Replaced the hammer (was dented already) and the hammer spring (it snapped but the gun still worked, not consistently however and I found out by chance only, while disassembling it)
5. Replaced the piston seal, when it’s old it hardens and does not seal against the cylinder too well - here you’ll loose some air for sure
6. Original KWA release valves are much better than the aftermarket ones, really makes a huge difference so make sure you replace them
7. Double feeding may happen when it’s time to replace mag lips
8. Gas seal on the top of the mag needs replacement or a shim if is too old - will not seal against the bolt
9. I’ve added some electrical tape inside the mag well to reduce mag wobbling, it help a lot with consistency but make sure your mag release is in good condition, when used it will position the mag lower than it should sit and of course you’ll loose gas there.
