Disclaimer:
Armory Craft performance parts are intended for installation by a qualified gunsmith or licensed armorer. While Armory Craft parts will fit without any issues in a vast majority of firearms, due to small manufacturing tolerances present in all mass-produced firearms, in some very rare cases fitting will be required by a qualified gunsmith or armorer. Therefore, Armory Craft is not able to guarantee perfect fit and functionality in every firearm unless the part is properly fitted. Thank you for your understanding.
