Promoted Pawn will be offering a self-zeroing optic rail.
This rail allows you to share an optic between the PS90 and another weapon without zeroing between swaps! That's because this rail is adjustable in windage and elevation. You might, for example, take the expensive holographic sight off your AR and mount it on your PS90, and after initial adjustment of the rail your optic can be quickly swapped between the AR and PS90 as a modular component. For optics with quick throw levers this can be done in seconds!
It has a BUIS.
It's better than the factory rail in price, and IMHO design.
I expect to have these for sale on the promoted pawn website this Friday.
