All the correct items arrived (3x hi capa mags and 1x oversized 50rd mag), but the o-ring on one of the valves was damaged and it leaked gas. I asked for a replacement o-ring set or full valve assembly but never got a reply. Not completely happy with the service.
I have ordered from SIXmm a couple of times now and the service is excellent; shipping is fast and very reasonably priced. I got the Army Force Magwell for my KJ Works KP-07 and it was a drop in fit, no need for adjustments. I will definitely order again.
Nice and easy to install!
It works perfectly.
Stock works great, minimal wiggle when in the open position
