PSA 18" Rifle-Length 6.5 Grendel 1:8 Stainless Steel 15" Lightweight Opinion?

[LOTO]

I was getting ready to pull the plug on a PSA upper but I received an email from Bear Creek yesterday morning and the 20" uppers were back in stock and I ordered one. I've read a lot of good and a lot of bad on Bear Creek but have got to say that I must have hit them at a good time because 30 minutes after my order a tracking number was created, UPS picked up package shortly after, and my Grendel is currently in transit and scheduled to be delivered on Monday.

BCG and CH are included
