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.

Our FRS-15 kits are not only designed to be the most ergonomic solution for featureless conversions, they are also tailored to meet our customers individual needs and budgets. Many people use their rifles in different ways and our Standard and Enhanced kits allow for maximum utility. The difference in the two kits is the Trunnion Cover. The Standard 4300P-AKM1 Bundle Kits are tailored more for those who primarily shoot from a bench or prefer a two point sling. The Enhanced 4300P-AKM2 Bundle Kits include two additional quick detach sling hard points injection molded into the trunnion cover. The advantage is that if a user prefers a single point sling, the center of gravity is in line with the barrel which keeps the muzzle pointed straight down.
