I just finished putting a 20” BHW barrel chambered in 6mm Creedmoor on a Palmetto PA10 rifle. Used an Odin adjustable gas block JP high pressure bolt and Larue MBT trigger. The factory Hornady Black,Match and Precision Hunter Ammo all have shot under MOA consistently as well as handloads with Sierra 107’s and 108 ELD’s with H4350. I agree something on the AR15 platform will be lighter and quicker handling but if you want an AR10 by all means go for it.
