I received mine and ran it during a carbine class this weekend. Comments:
1. Machining, fit, and finish are excellent
2. You need a big wrench / big adjustable wrench to torque it on to the can using the 1 3/8 inch flats and a spanner wrench on the can
3. I ran it on a YHM Turbo K2 and a TBAC CB muzzle brake. Rifle was a semi-auto AR 11.5" 5.56mm.
4. Hand snugged at the beginning of class. Can never moved/loosened over the roughly 650 round class. It got somewhat hot at times during periods of moderate rate of fire. Was able to remove can by hand without any drama when still slightly warm at the end of the day.
5. All in all I like it and this is great for those of us who are heavily invested in TBAC muzzle devices but still rock some non-TBAC cans or for those who just want to run TBAC brakes or FHs which, in my jaded opinion, are little works of art.
