I finally took a plunge and ordered the PSA 18" upper receiver in 6.5 G obviously.
I added a muzzle brake (not really necessary but I love to see impacts), and a Bushnell Nitro 4-16x44 FFP with MIL reticle.

After some issues with double firing (trigger issue) and the bolt not locking back (combo issue of trigger resetting and gas block not adjusted right) I began to get this thing dialed in.
I bedded the barrel in loctite and let it setup for 48 hours. On the first range trip after I was able to get consistent groups and all of them were at or barely above an inch.
All this was while shooting Hornady American Gunner ammo so I know with reloads I will be able to get this gal dialed in pretty good.
This week I took the Grendel out and was feeling really stable and confident so I shot a 100 yard group that resulted in 0.87 MOA:

Nothing to to terribly excited about, as this is my least precise rifle, I ventured out to 305 on paper for a 1.41" or a 0.43 MOA group:

Some may think it strange that I could shoot better at 300 than at 100 but I tend to have the same issue with my favorite 308. I will shoot right at an inch at 100 then crank out repeatable 1.25" groups at 300. I think I just figure it is good enough so I just shoot.
The other day when I went out I borrowed a Magnetospeed so I could confirm some data. Unbelievably I was getting 2550 average speeds for the American Gunner ammo. Bear in mind I am at over 8k feet ASL where I shoot so this may be a huge contributing factor to my muzzle velocity. I will take it! 1000 ft/lbs at 400 and 2000 ft/sec.
Anyways, I am super happy with the results so far and will have new posts soon when I fire my reloads that are sitting in the garage...
