It has arrived! Took a stroke of luck, but a Hide member mentioned he saw these in stock and I snagged one just as they were down to 3 left.

20", 1:10 twist, rifle length gas system, medium contour, .750 at the gas block, 5/8-24 threaded with a 11 degree target crown, & guaranteed sub-MOA with match ammo.
On to the fun stuff. Stripped out the old barrel (a DPMS AP4 barrel that shot around 1 MOA with match ammo @ 200 yds, probably more limited by me than anything else), and got the Seekins adjustable gas block installed.
On a side note, the roll pin opening on the Seekins gas block is flat, not chamfered for ease of insertion like other gas blocks. After a lot of swearing and multiple hunts for the roll pin across the carpet, I just took a drill bit and chamfered one side of the hole, then hammered that fucking pin in.
On to my next woe: The medium contour behind the gas block seat makes it damn hard to adjust the brass tension screw on the Seekins gas block. I'm definitely wishing I'd waited on the Wilson Combat gas block, which features a front adjust mechanism.
At some point during the week I'll run this over to the local shop and have the AAC 51T brake mounted and timed.
For now, I just cleaned the barrel out. There was a good bit of gunk in there! I ran a few wet patches soaked with solvent, then used a nylon bore brush for a little scrubbing, and here are the 5 patches it took to get it fairly clean.
