The Universal Mini Stock (UMS) is a universal mini stock to be installed on a rifle. Installing a stock on a "pistol" would be considered an SBR (short barreled rifle). If you have not paid the fees and received an approved tax stamp from the ATF, it will be illegal to possess an SBR. ALL NFA RULES APPLY!!!
