Geissele Mk1 MRGG 6.5 Creedmoor initial impressions

[jmornoinf]

My initial impressions with the Geissele Mk1 MRGG 6.5 Creedmoor are all positive except for the cost. Geissele really stepped up their game with this rifle. The machining and tolerances are awesome. There is absolutely no play between the upper and lower.

The fit and finish are second to none and the recoil is noticeably lighter than my KAC 6.5 22". I believe Geissele mitigated recoil with the phased array gas block and possibley the brass weight in the BCG...not sure.

I shot both Black Hills M1200(rifle designed for this ammo or the story goes) and Berger 140 Hybrid factory loaded. I was pleasantly surprised how easy it was on the brass. My KAC gun shreds brass ~3max firings.
M1200 - 2610 ave ~ this equates to 41.2ish of H4350. On the light side
Berger 140 - 2685 ave - this same ammo does 2750 out of the KAC 22"

Groups were ok for the first outing(see pic). I estimate this gun to shoot .75" or less with hand loads(will post new groups soon). AR10 gas guns are the most challenging rifles to shoot well(I bet someone on here will disagree). I have a 6GT blot gun that I reliably shoot .250" groups consistently...It pains me to see a 1" group.

I just ordered mine. I'll report back after getting a few hundred rounds through it.

What do the loaded rounds look like when you chamber them out of the mag and then carefully extract and eject them? Any COAL changes? Tip deformation? Scratches?
