Looks nice.
I thought that looked like a Gunfighter CH.

Don't know if you've purchased any barrel install tools yet but I will vouch for the Gem State wrench.
$40 shipped and made in Idaho, USA.
Laser cut from 1/4" plate.

I'll send it up if you want to try it and the Brownells clam shell.
I also have a 6x lifetime supply of AeroShell 33MS which is the official moly-fortified grease for the barrel nut.

I've been using the Brownells clamshell which is very well made.
The Spikes Block Works gets good reviews as well and there is a Block Works knock off on Ebay getting good reviews.
The knock off is US made probably by a retired machinist...machined from HDPE I believe.
