Got most of the parts in, scope should be here today, Leupold 6.5-20x50 Vx-III. Upper and Seekins GB were picked up here on this site used, Aero lower, Velocity 3-lb. trigger, SLR rail, RRA OD stock off AR15.com EE, YHM FS mount for my LT can, Specter sling. Went together smooth... used .005" shim stock for a press fit of the barrel into the upper.
As normal, I scrubbed the barrel before the first round was fired. Seemed a little more dirty than other new barrels I've had. Almost appears to have a reddish-orange tint, like signs of rust, I sure hope not. Patches felt smooth for the most part.
Used Hornady 123gr SST to check function... first round locked the bolt up tight. About 10 significant mortar attempts finally broke it lose. Brass seems to have a lot of scoring from machining... see below.
Fired a second round and the action did not cycle BUT the round came out effortlessly this time. A quick adjustment on the GB and the third round ejected perfectly at 3:00 and bolt locked back. Loaded two rounds and function was 100% with bolt lock back, all at 3:00 ejection at about 4 feet.
So far, so good...
