Great news, I was just on the Primary Weapons website cheking out optics too.
Nice to hear that their service is excellent.
It was a high cantilever and the HK SL8 style sights I have will not co-witness with the optic. I need the standard low mount apparently.
I don't want to hijack this thread. Is there a thread on this forum explaining why I would bother spending alot of money on an Optic just to have it blocked by my front ron sight. Maybe it's just me, but I just don't see the point.
