I have owned one for two years now. First year had problems with groups drifting left or right. After remounting it and using locktite on all screws I have no problems. I am so glad I don' t have to strain looking thru peepsights anymore. Just curious if any others here are using it and your thoughts on it.........dabow

I have one and they work great. I dont use mine because of pope and young rules. But actually there very accurate when mounted right.

How exactly do they work?
