Disassembly Fixture for FN 509/FNS-C by Apex Tactical. Fits FN.

The Apex FN Disassembly Fixture solves the single most frustrating step in maintaining your FN 509 or FNS Compact: removing the unlocking block pin. For $25, this tool turns a high-risk operation into a controlled, repeatable process. It is specifically designed to hold the pistol frame securely, guiding a pin punch directly onto the pin while protecting the surrounding polymer. This is not a universal part; it is a dedicated fixture that matches the contours of the frame, so the punch stays on axis and the frame stays put.

Real benefits for your workbench:

  • Precision alignment. The fixture locates the frame so the punch hits the pin square, reducing the risk of slipping and marring the frame or damaging the pin face.
  • Stable hold. Use it on a solid surface—a vise anvil, concrete floor, or a workbench positioned directly over a table leg. It is not designed for flimsy tables or countertops.
  • Time savings. No more fighting with awkward angles or improvised supports. Set the frame, align the punch, and drive the pin out cleanly.
  • Built for California owners. As someone who navigates the roster and magazine limits, you know the value of a tool that protects your investment. This fixture helps you avoid costly frame damage during routine maintenance or aftermarket part installation.

Important fitment and usage notes:

  • Compatible with FN 509 (all variants) and FN FNS Compact pistols. Not for use with other models.
  • Must be used on a solid surface. Kitchen tables, countertops, or hollow-core workbenches will not provide the necessary stability.
  • If the front unlocking block pin has a damaged, mushroomed, or non-flat face from previous attempts, this fixture will not correct that condition. You must dress the pin end flat before using the fixture.
  • 100% Made in the USA, Phoenix, AZ.
  • No guarantee that the fixture prevents all frame damage—pins that are seized or previously damaged require additional attention.

Specs and compatibility: The fixture is machined from steel with a precision-milled pocket that accepts the FN 509 or FNS Compact frame. The top surface provides a flat, stable platform for a punch. Overall weight is minimal, designed to stay put under impact. Works with standard 1/8-inch or 3mm pin punches. The fixture itself measures approximately 3 x 2 x 1 inches.

For the California gun owner who maintains their own firearms, this is a simple, effective tool that eliminates guesswork. It
