New 6.5 Creedmoor AR Upper

I took a fresh built 6.5 Creedmoor upper out today for initial testing. It has an AR Performance barrel and JP Enterprises free float tube. I haven't put on a flash hider or muzzel brake yet. It has a Superlative Arms adjustable gas block. Also a Vortex 4 x 12 scope. I was shooting SIG 140 grain Match. It took three shots to zero the scope, then a four round group. I had a 3 hole, 1/4 inch group with a called flyer for the fourth round. First few shots were ejecting about 2 o'clock, one adjustment of the Superlative block and they were popping out at 3 o'clock, traveling about 5 feet, and recoil was slightly reduced. I used my 308 lower for testing, but am building a dedicated lower for this one. I'm not a big fan of large frame AR's, too heavy, and this will be my last one. But this might be the most accurate rifle I have judged by group size. Guns are fun.

I have that same barrel. Very accurate and would be perfect for hunting. But my groups opened up on the 4th or 5th shoot with that barrel.

Is that SA one of the "blow hole" bleed off blocks and are those different vs the SA blocks that work on .223?
