Precision reflex fixed sights - Precision Reflex Pri Fixed Front/Rear Sight Packages

DO NOT BUY THIS GARBAGE!! I would give zero stars but it wouldn't be posted. I bought these from OP 3 months ago and had hardest time getting front sight post to adjust (even after I bought the P.R. sight tool) because of the circular front sight adjustment cut-out was too small. SIGHTS DON NOT HOLD AFTER SIGHTING IN despite me using Loctite to make sure they would not loosen. 3 trips to range and sights were off every time. Would sight-in, shoot a couple mags to make sure hold and sight picture consistent, then go home. Next trip, no joy!
I tried to return the sights for a store credit but was denied. I admit it was past the 30 day return window, but it took several trips to the range to realize there was a problem. Also, one would assume that after getting gun sighted in it would remain so, especially if kept in gun safe and not slammed around. OP staff was polite and prompt with email responses, but I am disappointed in their refusal to take back the sights. I was asking for return for refund OR store credit. They would obviously have an easier time returning the sights to PR and they keep me as a customer. Now, I have to try to get money back from Precision Reflex, and I already know what they'll say - we can't help you because you didn't buy them from us. Don't think I'll be making any purchases from Optics Planet again.

I waited to write this until AFTER I replaced my sights. I Bought Magpul MBUS polymer flip-up front and rear sights from local gun shop for 2/3 the cost of Precision Reflex and WOW, my AR shoots straight.
