I got a buck rail modular moderator, with the intent of putting it in front of my buck chrono.
But that did not work, and i know why, the chrono are off axis so did of course not put replacement moderator on it.
Upon testing it, it do moderate just fine, but add a high pitch sound that just is not there with my Huma moderator or the Finnish made one i have.
So i thought i would try something.
Before:
Now:

Had to take a few 1/10 of a mm off to make it fit inside the 38 mm ID carbonfiber pipe with a light press fit.
80 grit sand paper took care of that before my wrists got tired.
No idea if it have improved on the sound profile, but carbon fiber always look good.
