Great for tucking in your suppressor by Schrieves, Verified Owner, May 1, 2023
I wish I knew how wide this rail was. It’s wide enough to go over your suppressor but that was not my intentions. Very lightweight. Only issues I had was installation was a bit tricky. The design could have been simplified.
