This Split Rear Rail System offers the highest value and quality when looking to improve the fitment and performance of your double stack 9mm P80™ frame. There is no better bang for your buck.

Why Split Rear Rails? This patent pending two-piece rail design allows better alignment across the frame, rails, and trigger housing and provides for a smoother build experience when installing your lower parts kit. 

As one of the industry leaders of the 80% market, these rails are properly engineered and manufactured with a connector clearance cutout so builders can avoid the “mush” caused by other rear rail systems, keeping your trigger feeling the same way without any unnecessary filing, grinding, or “tuning”. 

These rails are solidly made from premium stainless steel billet, precisely milled, and then accurately checked for dimensional tolerances with coordinate measuring machines.
