A quick and easy way to smooth out your Polmyer80's slide.
The polymer80 provides you with a distinct advantage over factory GLOCK® handguns: Its rail system is completely removeable, which means it's interchangeable and can be upgraded.
ROOK Tactical has machined this upgraded Locking Block Rail System from high-quality stainless steel with insanely tight tolerances. That translates into a smoother and more reliable slide with better cycling and brass ejection.
Compatible with standard Polymer80 frame pins and ROOK's upgraded "anti-walk" frame pins.
