    Took it out yesterday and sighted in. Super accurate barrel at 100 yrds. Does not like 223 tulammo in 55 grain. trouble in ejecting. Cycles 5.56 in 55 grain fine. Will try 223 in heavier weight bullet and update progress. Will also different buffer weights. Recoil was light and made target acquisition quick and repeatable. In a nut shell a great barrel.

    Amazing value. After break in and testing a few handloads this upper can do 5 shots into one jagged hole at 120yds. The best load was 55gr Nosler Varmageddon black tip over 24.5grs Ramshot TAC and Winchester primers. OAL 2.25 with a light crimp (LEE Factory crimp die.). Used Remington cases. Cannot go wrong with this upper.
