Thread: NEA AR 18'' barrel re-profile

I have changed the barrel on my NEA 18'' heavy barrel to a faxon 16 gunner series. So now what to do with the spare barrel, thinking of getting it turned down to a lighter profile of .640 under the handguards tand .640 from the gas block to the muzzle and maybe shortening down to 16'' in the view to suppress it later with a adjustable gas block. Anyone been down this path.
