ROOK Tacticals PF45 Compatible Precision Machined Rear Rail System is HERE! Machined from solid Billets of the same 17-4 material as our front locking blocks, these high quality precision rails are designed to work in Tandem with the ROOK Tactical Front Locking Blocks to make for easier slide fitment and a more precise slide action. If your holes are drilled right these will fit. 
 
ROOK Tactical Reccomends watching the install video below before trying to install to assure proper fitment. Some fitment and adjustment of the rails, connector MAY still be needed in some cases if the holes are drilled slightly misaligned or if using an aftermarket connector. Some fitment my also be needed if the rails seem a little wide its down to the mold changing over time on the polymer injected lowers.
