how to install glock channel liner without tool

Installing a Glock channel liner without the appropriate tool can be challenging, but it’s possible with some improvisation. The channel liner is a small tube that sits inside the slide of a Glock pistol and serves as a guide for various components. Here’s a general guide on how to install a Glock channel liner without a dedicated tool:

Materials You’ll Need:

  • Glock channel liner (new or replacement)
  • Small Allen wrench or punch (smaller than the channel liner)
  • Soft-faced hammer or mallet
  • Vise or clamp (optional)
  • Bench or solid surface


  1. Safety Precautions:
    • Ensure the firearm is unloaded and the magazine is removed. Keep the gun pointed in a safe direction.
  2. Prepare Your Workspace:
    • Set up a stable workbench or solid surface where you can perform the installation. Ensure there’s adequate lighting.
  3. Inspect the Channel Liner:
    • Examine the Glock channel liner to ensure it’s in good condition and free of any defects. It should be clean and undamaged.
  4. Position the Slide:
    • If you have access to a vise or clamp, you can secure the Glock slide in it to keep it steady during the installation. Make sure not to overtighten, as you don’t want to damage the slide.
  5. Align the Allen Wrench or Punch:
    • Take a small Allen wrench or punch that is smaller in diameter than the channel liner. Hold it vertically and align it with the channel liner hole in the slide.
  6. Insert the Channel Liner:
    • Carefully place the channel liner over the aligned Allen wrench or punch. Ensure that it’s positioned correctly and directly above the channel where it needs to be installed.
  7. Tap with a Hammer or Mallet:
    • Gently tap the channel liner with a soft-faced hammer or mallet. Start with light taps and gradually increase the force as needed. The goal is to drive the channel liner into the slide.
  8. Check the Installation:
    • Periodically stop and check the channel liner’s position. Ensure that it is flush with the slide’s surface and properly seated. You may need to tap it a few times to fully seat it.
  9. Test Functionality:
    • Once the channel liner is installed, function test the slide by moving it back and forth to ensure it moves smoothly and that there are no obstructions caused by the channel liner.
  10. Final Inspection:
    • Carefully inspect the installed channel liner to confirm that it is securely seated and flush with the slide’s surface.

It’s important to exercise caution and patience when installing a Glock channel liner without the proper tool, as you don’t want to damage the liner or the slide. If you find it too difficult or risky, consider seeking assistance from a professional gunsmith who has the necessary tools and expertise for this task. Additionally, always follow Glock’s safety guidelines and recommendations when working on firearms.
