Is that the Sharps Reliabolt?
I was meaning to get that and try it out.
Gotta wait until I start having issues with my homemade AR, first. Went to the range this afternoon to zero my scope, and I had no issues with it at all.

Well, with the exception of the scope being mounted too low and the buffer tube yanking out my mustache whiskers.
