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
