The first upper I had for my Grendel AR was a BCA upper. My original barrel was an Odin 18 incher. This combo did not shoot well at all with the only Grendel ammo I had at the time, the now defunct Hornady 123gn AMAX. Not yet knowing BCA products could be hit-or-miss items, I was thinking the barrel might be the problem. So, I bought a Wilson Combat barrel for it. Well, that didn't improve my groups any at all. 
About that time frame is when I joined this forum & started learning about the 6.5 Grendel. It was reports about BCA's lack of quality & PF's high quality that prompted me to buy a PF upper. The difference in groups after installing my WC barrel in the PF upper was light-years different. From the BCA 3"+ to under .75" with the PF using the same AMAX ammo had me grinnin' like a Cheshire cat.
One thing I noticed when I was removing the barrel from the BCA upper, the fit was quite sloppy. I could wiggle the barrel around in the BCA upper. When I installed the barrel in the PF upper, I had to do a thermal fit (warmed upper/cold barrel).
Now I'm wondering if the Odin barrel I have was prematurely blamed for the original huge groups. I've got a BCM blemished upper that's still in it's original wrapper. I might have to put the Odin in it & re-evaluate it.
