I finally found a Six8 receiver set at GrabAGun and am breaking in Magpul mags using handloaded dummy cartridges (Hornady fired brass, 100gr Match Monster bullets). A bit of filing on the internal ribs and removal of 2 turns of the mag spring allow 19 rounds in a 20 round mag and 29 rounds in a 30 round mag.
I have a flat wire action spring in my 12" setup and it's getting easier to push past the drag on the mag feed lips. Lots of hand cycling...
I'm headed to my gun club in the next couple of days to zero and function test. If all goes well I'll pick up a bunch of mags and make this my go-to Grendel semiauto.
