Let me guess here... you tried being clever but instead hardcore buggered up your P80 build and the manufacturer won't help you out? Don't worry, mo' frigging Wojtek has got you covered. This rail is a replacement for the P80 9/40 rails and made right here in the USA out of laser cut and precision stamped 304 stainless steel. Depending on your build you may need to modify this rail a skosh but it, by and large, should drop in and get you rolling.
