kwa m4 hop-up swap issues
 

the last game i was at my gun wouldnt fire rite (no bbs then like 3 roll out then one normal then roll out or shoot like 5-10 feet) i figured it was the hopup so i bought a G&P one peice metal one, cut out the required area and now its not firing the bbs even when theyre sitting in the hop-up properly ......does anyone have any input on this issue or tips on the swap i mite have missed
kwa is a marui clone i believe ie. 2 peice hop-up unit
thnx

Did you change the nozzle? The KWA nozzle is designed to work with just the stock hop-up. Modify makes decent nozzles but other than that I know know any other details. I still use the stock KWA hop.

as said the kwa hop up is slighly different from the marui one... the nozzle is also not the same... your best bet would be to try a marui nozzle on the mechbox but i'm not even sure it'll work... it has to be the correct lenght.
