After months of development and testing, Thordsen Customs is excited to bring our FRS-15 Gen III Stock to the AK platform.  Until now, no featureless option has existed for AK-47s that allow full functionality and safe operation. With Thordsen Customs’ line of AK Adapters our highly popular FRS-15 Gen III stock is now compatible with the most popular modern sporting rifle in the world. 

The AK-47 platform is a very old design with many variants created over the years. Due to the way they were designed and are manufactured no two AKs are exactly alike. Our AK-47 kits are designed to fit the most common modern makes and models but still may require some adjustments or modifications to achieve the best fit possible.  Please refer to the instillation instructions link above to see which variation is appropriate for your rifle.

I like it!Review by Jim
I bought 2 of these for my NPAP's. Much better than a spur if you actually want to shoot your AK. Mine both came with missing 4" cap screws that are not available anywhere locally. But Thordsen sent them out ASAP.
These may look a little goofy, but the feel in hand is not too bad and actually make make the AK A little more ergonomic. (Posted on 6/4/2018)
