Not very well made - Precision Reflex Pri Fixed Front/Rear Sight Packages

I returned this because I ordered the wrong set - I meant to order the set with the trumb wheel adjustment for the front sight. But In the short time I had this set of fixed sights, I noticed that the detent / set pin on the front sight would not spring back when depressed. With a bit of fiddling and some WD-40 penetrating spray, it came back up. While fiddling, I noticed that the fit and tolerances of the parts were not as precise as the company name might have you believe. Finally, the rear sight thumbwheel adjustment wasn't very firm or secure. It's easy to see how something could brush against it and knock it out of zero. So I swapped these out for a similar setup from Troy Industries, which is just better stuff. Closer tolerances, tighter fit, better mech.
