Does the MWS have to take STANAGs
if not, consider the Savia PCC. Takes hicapa mags. If you’re already doing IPSC, I’d wager you’re running a hicapa. The PCC takes hicapa mags so you don’t need to invest in new, heavier mags.
its largely MWS spec. It does about 1.3J out of the box with the stock set up. You’d need to do very little to get it shooting at 30m accurate. I think all I needed to do was a guns modify spring set and pink flamingo hop unit. It’s shooting 40m flat with respectable accuracy on 0.28s.
