As we are transitioning to Soviet Arms, your receivers may be stamped with our new AK Soviet Arms logo on firearms manufactured after 3/8/2023. This will not affect the quality or function of the firearm as they are the same AK receivers used for our AK's. This will only be a minor cosmetic change moving towards our Soviet Arms AK's.
