How to Make a Kydex® Magazine Carrier with an HDPE Mold and Trim Jig

Finished Kydex® magazine carrier made with an OxCreek Tactical, Inc. mold

Our CNC-cut HDPE molds and router trim jigs let you turn out clean, repeatable Kydex® and Boltaron® magazine carriers without hand-shaping every one. This video walks through the whole process, from a freshly pressed shell to a finished carrier.

What you need

  • An OxCreek Tactical, Inc. magazine carrier mold and its matching router trim jig
  • Kydex® or Boltaron® sheet, plus a way to heat it and a foam press
  • A drill with a 1/16" bit and a center drill
  • A bandsaw
  • A router with a flush-trim (bearing) bit
  • Two 3/8" 8-32 screws to hold the shell on the jig
  • Clamps and your carrier hardware

Step by step

  1. Drill breather holes. Before your first press, drill 1/16" breather holes in your new mold in a similar pattern to the one shown. They let trapped air escape so the material pulls tight to the mold.
  2. Bandsaw the shell. After pressing, trim the shell on the bandsaw, following the molded outline. This leaves just the right amount of material for the router.
  3. Drill the indicator holes. Drill out all of the indicator holes molded into the shell. A center drill works best.
  4. Mount the shell on the trim jig. Attach the shell to the router trim jig using two 3/8" 8-32 screws.
  5. Set your router bearing height. Stop and set the bearing to the correct height for each trim jig before you cut. Then trim the shell going left to right only.
  6. Heat the center spline. Heat only the center spline so the heat doesn't spread and deform the blocking.
  7. Fold and clamp. Fold the spline over the back of the magazine and clamp it to the body.
  8. Finish and assemble. Once the spline has cooled, finish your edges and install your hardware.
