KWA M4A1 hopup/Barrel
So I went to upgrade my gun recently, and found that my upgraded barrel is larger than the KWA hop-up chamber. The barrel simply won't fit into the chamber with the hop-up rubber on. looking at the stock barren and my upgrade barrel side by side reveals a visible difference in size, not much, but it's there. Also the barrel I tried to install is a very tight fit in the outer barrel itself. so it's not just the hop-up rubber being too big.
my questions are these.
What barrels will fit the stock KWA hopup?
or
What hop-up units are compatible with the KWA gearbox since the air seal nozzle has a notch in it that fits into the KWA hop-up chamber?
Ive also heard standard TM airseal nozzles don't work with the KWA gearbox.. can anyone clarify this?
PS: does anyone know if D-boys m16 mags will fit in the KWA? I need a definite yes or no on this. Thanks!
