I used to have a chest rig from that company, the Pioneer m23.
It was interesting.... very purpose built. The utility pouches didn't hold anything too well, except maybe grenades, which I don't really have access too. Instead of drain holes they had big slits in the bottom corners of each pouch. So nothing too small would fit.
The magazine pouches were HUGE. You could EASILY keep two AK mags in it, with room to spare. If I had any 40-rounders, I have no doubt they'd fit as well.
The shoulder straps were this weird thick stiff webbing, very inflexible and didn't really like having a rifle butt pressed against them. The rifle wouldn't 'catch' and slip around.
Two (count 'em, two) sheaths built in to keep bayonets. They only fit the ones with fiberglass, not the rubber insulators.
It was ok, but really not for me. The pouches were of no use to me since you couldn't keep much in them. It went on a bit difficult, but came off very fast, go figure. It was fun to show people the tags with Cryllic on them, though.
Perhpas the zip-front vests would be more useful, as long as the pouches don't have that silly opening at the bottom...
