Looking to put a Pro Mag 137 flip up dual aperture rear sight on my AR. Just want to know if anyone on this forum has one and can tell me what they think of this rear sight. I do know it is made in the USA and I am a fanatic keeping everything that way on my AR. But I confess I have a Tru Glo riser that is made in China.
That will change soon.
