Magazine Pad Drilling Fixture Instructions

  1. Disassemble the magazine by removing the follower and spring.
  2. Place the magazine in the jig with the front edge facing the tensioning screw.
  3. Turn the tension screw until it just makes contact with the nose of the floor plate.
  4. Once contact is made, tighten the screw 1/4 turn or ONLY until the magazine is firmly in place.

    DO NOT OVERTIGHTEN the tension screw.


  5. We recommend placing the magazine and jig in a bench vise (as shown) for easier
  6. drilling of the base plate. Use soft jaws or a leather or rubber pad against the magazine body if available.
  7. Place the jig on the top edge of the vise jaws. Light, contact is all that is needed.
  8. DO NOT OVER-TIGHTEN THE VISE ON THE MAGAZINE. The jig will securely hold the magazine, resting in the jaws of the vise.
  9. Using an electric hand drill and the #43 drill bit provided, drill the holes in the magazine
  10. using the holes in the fixture as a guide.

    NOTE: Many early blued and military magazine base plates are HARDENED and may require an additional step to help the drill bit start cutting. Nickel or Hard Chrome plated magazines will also be difficult to drill. We suggest marking the places for the holes with a center punch and use cutting oil or light machine oil on the tip of the drill bit. DO NOT use WD40 or synthetic oils.

  11. Use a medium to high motor speed with a constant downward pressure, while drilling.
  12. The jig will help keep the drill bit from flexing.

  13. Attach the base pads using # 4-40 Stainless Steel thread cutting screws, or tap the holes with a 4-40 tap.
  14. Thoroughly clean the inside of the magazine body to remove any remaining oils or metal shavings before reassembly.

5 out of 55 out of 55 out of 55 out of 55 out of 5 A good idea and design, saves you time and mistakes, 4.11.2013
Reviewer: jr lawson (Ft Knox, KY)

I found this drilling fixture after I had bought a bunch of Mil Surplus mags to put mag pad bases on. I didn't think such a simple design would work, but I was wrong.
I burnt up the drill bit on the first 2 magazines and was mad as hell.
I called the company and spoke to a guy named Dan who helped me realize my error. I had tried to drill too fast and the drill bit would not bite.
So I marked the holes as he told me to with the jig, then used a center punch to make a small indent and after that the drills cut right through on slow speed.
I have drilled 20 mags now with perfect holes for the pads.
I have to say thanks for a good product and unexpected good customer service.
They even sent me out a couple of new drill bits at no charge.

Reviewer: R. Gordon (Portland, OR)

Making this tool available was a brilliant idea. It does what it is described to do and does it very well. I have used it for more than 20 magazines now and the holes are perfect, and this makes the base pads also fit perfectly. Incredibly simple. I am very impressed and satisfied with it.

Reviewer: G. Goodman (McAllen, TX)

This fixture saved me a lot of time and trouble installing pads on all my magazines. The instructions were clearly outlined and easy to follow. It holds the magazine in place and you will have an easy time drilling the holes.
The only thing I suggest is don't try to drill too fast. Use a slow to medium speed and the drill cuts right through the base.
Using a 4-40 tap for the screw holes is also a good idea.
