Apex 5.00” Slide for FN 509 - RMR Slide Cut

This is a stripped slide for your FN 509 pistol. You will need to supply all of your own internals from your factory FN 509 slide, and you’ll need a barrel.  All spaces in the slide accept factory FN components.  For optimal performance, all Apex parts for the 509 fit this slide.

REQUIRES ALL INTERNALS AND A 5” BARREL FOR THE FN 509.

We are no longer offering complete slides on the website.  If you're interested in ordering our slide for your pistol fully assembled and ready to install and shoot, contact our Customer Service team via email or phone to place your order for a Slide Completion Kit, slide, and barrel.  Due to pre-existing agreements with our vendors, we're only able to sell certain components installed into a complete slide.

Features

The Apex 5" Slide is machined from Stainless Steel and cut for RMR Optics. Features include:

• Front and Rear Cocking Serrations
• Suppressor Height Black on Black sights
  • Note: the dovetails are cut to accept any sights that will fit an FN 509 factory slide
• Black Nitride Finish

This slide is cut with the appropriate geometry to directly mount a Trijicon RMR which accepts a Holosun 507C and like optics.

Check the specifications from your optic manufacturer for the proper torque on your screws. If no recommendations exist, we recommend all screws be torqued to 20 in-lb (Inch Pounds) MAXIMUM.
