Availability: In stock

* Required Fields


BATFE continues to flip flop on whether “Stabilizing Brace” products are considered a defacto “rifle stock”, which may change the designation of your AR, AK and other pistol variants to a “firearm” or “short barreled rifle” under the National Firearms Act of 1934.

The Thordsen Customs line of Pistol Cheek Rest kits were introduced in 2014 and have withstood the test of time and scrutiny. They are designed and intended to provide a third point of contact on the users cheek and provide a viable solution for AR style pistol lovers to enjoy the accuracy, comfort, utility, reduced weight, and the sexy lines of their AR pistol.

As a result of popular demand by our current customers and those who want to swap out their Stabilizing Braces, we have taken two of our most popular products, our Buffer Tube Covers and 3D printed Snap-on Cheek Rests, and combined them into a new bundle called the Pistol Cheek Rest Conversion Kit.

Our buffer tube covers are injection molded in 33% glass filled nylon and our popular Snap-on Cheek Rests are 3D printed in ASA co-polymer. Both are designed for maximum durability, utility, and good looks to the exacting quality standards that our customers have come to expect.

The Bureau of Alcohol Tobacco Firearms and Explosives, Technology Branch has affirmed that the Thordsen Customs Buffer Tube Cover/Saddle combination is a “CHEEK REST” and IS NOT a "rifle stock”. It DOES NOT reclassify an AR/AK type "Pistol" as a "short barreled rifle" under definitions established by the National Firearms Act of 1934 or the Gun Control Act of 1968. However, BATFE does specifically warn that any misuse of, or modification to, this configuration that may cause a firearm to be used outside of its design parameters, such as being shoulder fired, may change its classification and may make a firearm subject to NFA and GCA regulations and/or illegal to possess.

It is the responsibility of firearms dealers and private firearms owners to know and fully understand all federal, state, and local firearms laws in their area. Thordsen Customs LLC will not be held liable for any misuse of its products and will assume that our product(s) comply with state and local laws unless otherwise notified by authorities.
