I have a new ER Shaw 308 21.5" bull barrel, threaded for Rem 700 (or 7). Barrel is short chambered and no crown. 1:10 twist, 4140 Chrome Moly steel, in the white. .950" at the muzzle.  $150 or trade for something of equal value.

I will fit to your receiver, finish ream and set headspace for a small fee.
