Wilson Combat 338 federal, 1:10 twist 16", 5/8x24, mid length gas, AR10 barrel. I have shot 250-300 rounds through it. Would be a great suppressor host. I swapped it out for a 20" for a bit more velocity. $165 shipped
Compass Lake Engineer (Krieger blank) 20" heavy barrel .750" gas block, 1/2x28 muzzle 1-7.7 stainless, rifle length gas. The barrel has had alot of rounds through it, I got it used from a High Power shooter and I have shot it a bunch. Not certain what the chamber is (5.56, 223 Rem, 223 Wylde) but it shoots 223 fine. Before I pulled it I shot some 80gr SMK's single loaded sub 1 MOA and mag fed 52gr match hollow points shot really well as well. Sticking with 16" or less for 223 ARs $65 shipped.
