Perfect for mounting/indexing QD suppressor mounts.

Written on Feb 13, 2020

The faces of the washers are precision ground. That guaranteed flatness and parallelism between the front and back surfaces of these washers is what is really necessary when using these for mounting/indexing a suppressor QD mount.

I used one of these on my precision AR-10 build and after I installed a Surefire SOCOM QD suppressor mount and properly torqued/indexed it onto the barrel, I checked alignment with a suppressor alignment gauge rod with the suppressor attached.

Alignment and indexing was perfect - giving me 100% confidence I would not get a baffle strike on my first shot.

It works perfectly!
