Compliance AK47 Magazine Floor Plates

The prohibition on the importation of non-sporting firearms under 18 U.S.C. section 922(l) and 925(d)(3) allows the prohibited AK47 to be assembled provided it does not contain more than 10 of the parts listed in the legislation. Part of the process of building a semi-auto from imported parts involves deciding which parts to replace in order to be compliant. For more information on the compliance issue, you can visit the Web sites listed below. Thanks to the 1919A4.com board for their help with this.

When trying to satisfy the ATF compliance parts count, the pistol grip and gas piston are two parts easily obtainable, and most often replaced with US made parts. However, if the gun in question is a vintage Type 2 Kalashnikov, sacrificing the rare fluted gas piston and original checkered pistol grip is out of the question. Magazine followers and floor plates are on the compliance parts list, so replacing them is an alternative.
Slab side and ribbed AK47 magazines

A magazine follower for the AK47 is available from TAPCO. Here is a link to their site:

I could not find a source for floor plates. If you are aware of a source, please contact me at jon@liberatorcrew.com so I can include that information here.


Parts breakdown for the two type of magazines covered here.
THE FLOOR PLATES
The two types of floor plate are shown at left. The early slab side magazine has a smooth floor plate, whereas the ribbed style magazine has two raised areas, one round and one oval. The tab stops on the two plates differ as well, as indicated by the red arrows in the photo above.

FABRICATION

Stamp the sheet before you cut out the profile. It will distort less if made from bigger stock. Lining up the die and coupling was easiest if I held the die above the coupling and then carefully slipped the sheet between them.

I used a 1/2" threaded pipe coupling and a 3/4" hex bolt turned down to 11/16" to stamp the round boss. I made a 1 1/8" wide by 22 gauge bending template from a worn out Japanese saw blade, but you can use the same material that the floor plate will be made from - 22 gauge sheet stock from Lowes. Don't use galvanized.


Metal sheers, 7" overall length.

Cutting out the blank is actually the toughest part. The tabs and curves are small. I use a small set of metal cutting sheers able to cut a small radius.

A sheet metal nibbler is useful for this type of work. I bought the cheap one shown at right. I used small files to finish up. Templates and dimensioned drawings are at the bottom of the page.
I can remember where I bought my Wells seamer, but you can get them from sheet metal suppliers on the Web. The Wells is the cheapest I found. I have gotten a lot of use from mine. At about $35, you may want to try something less expensive (like pliers or a ViseGrip and two small pieces of plate) if you only need them for this one project.


Using the seamer or similar tool, stand the two sides up as shown.

Mark lines where indicated on the dimensioned drawing at the bottom of the page.

Lay the template between the upturned sides. You may need to clamp the template in place too keep it from riding up one side as you bend the other.

Bend the sides over. I start at one end and work it a bit at a time. There isn't much there to get a purchase on, so if you have trouble you can try a new blank with taller sides and then cut them off after the bends are made, I did that on one but found it very time consuming to cut using a small Dremel cutoff disk.

Bend the side tight against the template to make it even, then drive the template out with a brass hammer. Bed the tabs up. Look at the original floor plate to see where this bend is.

It will be too tight to slide onto the magazine body, so turn the template sideways and pry up along the length of the bends.

So there you have it. It's not really as tedious as it sounds, and in any case if you can't find one commercially, how else are you going to get a compliant floor plate?
