The attachment mechanism is weird, is a screw thread thats more fine than the TBAC, and the locking part is basically a spring loaded latch.
Visually, it looks average at best, visible, lumpy welds.
It's also not the exact same color as the Mk22 despite being listed as the same.
However, it works great, sound is very comparable to the TBAC 338 Ultra SR in terms of the human ear.
It is super repeatable, the zero vs no suppressor zero is always .3mil down, .1mil right.
If its being paired with the Mk22, then buy it, because its the 'right' one. If its for general use, the TBAC would be my choice.
