No issues with the fitment, and it matched up perfectly with my barrel. I have also been shooting with zero problems. I want to do the pin portion of it one day, but for now, it’s nice knowing it is an option.

Mated up perfectly with my SOLGW barrel – as expected. Top notch!

I’ve used this on two builds so far and this will continue to be my first choice of gas block.
