I agree the stainless steel PSA 6.5 Grendel barrels seem better than Nitride. You gain approximately 25-60 FPS with a 20 over a 18 6.5 Grendel. If your going to use a suppressor the 18 will be handier and PSA 6.5 Grendel uppers usually ship with an adjustable gas blocks.
I have been around several PSA uppers in different calibers and theyre gtg.
