I have a varmint/long range upper for sale. It is an A3 receiver with a JP adjustable gas block, 24" 1:8 twist Stag Arms barrel, and free floated quad rail handguard. Round count is less than 200. The muzzle has been turned to .750 to accept a NRA Match Rifle sight, so it wouldn't be hard to thread if you wanted to. NO BCG OR CHARGING HANDLE. $500 shipped. I may trade; I'm looking for a 9mm pistol but may swap for something else, so let me know what you have.
