I'm in process of completing the upper with my Brownell's 20" faxon. I already did a cartridge drop into the chamber (bare-bones barrel), and then chambered with the bcg too (but not with the buffer spring, only the upper alone). Bullet seems to fit and drop out without issues, so field-check of headspacing seems gtg. No comparator, they're OOS everywhere.
I have some 105 factory's on hand, after a few break in rounds I will have brass to reload, so will start looking at powder recipes with the 90 Tgk and 103 eldx.
Possibly with either 2520 or CFE. Should get 50 ft/s faster in the lighter-gr pills, maybe more with the 90's.
