UPPER WITH 6315 IS SOLD.
Built two of these with exact same components. Barrel was bedded with Loctite 620 since fitment on the receiver wasn’t a thermal fit. Bolt and barrel passed Go and Field gauging, I don’t have a proper No-Go gauge to test. Will ship with both a Sprinco Green and Vltor Rifle spring as the other rifle build had a hard time eating PMC bronze with the Sprinco Green.
