Came into a stainless Spikes 6.8 8.5" barrel really cheap on the EE.  Its a Lothar Walther barrel. Their 6.8 barrels were used at Barrett were very accurate. Submitted a Form 1 for the reciever it's going to built up on.

Trouble is, the 1/2"x28 muzzle threads. Needing some sort of good flash hider that has those threads, but I guess I need a 308 sized  ID.
I hated going to weddings. All the grandmas would poke me and say "You're next". They stopped that when I started doing it to them at funerals.

Does BRT make a covert comp that will work?  I used that on one of my 6.8s (although it was rhe 5/8x24 threads)

9mm flash hiders have 1/2x28 tpi.

dpms and olympic arms both used 1/2-28 for their 6.8 barrels when the cartridge was being introduced.  That was the common muzzle thread before the spc II spec came along later.

Of course, I would suggest that you check the bore with a guide rod, but 6.8 is technically .277" diameter and it's not much larger diameter than 223.

Thanks everyone.

Would rather not. May want to direct thread my YHM Turbo K on it every now and again.

My Stag 6.8 barrel is in 1/2x36. I had to get a thread adapter to go 5/8x28 for my suppressor mount.
