Utilizing two heavy duty set screws, the UMS offers easy installation on receiver extension tubes.

*The set screw will be more secure on the cylindrical buffer tubes if you put a small dimple on the tube.There will be empty space between the stock and tube with most cylindrical tubes.

*The Universal Mini Stock (UMS) is a stock to be installed on a rifle. Installing a stock on a "pistol" would be considered an SBR (short barreled rifle). If you don't have the required tax stamp from the ATF, it is illegal to possess an SBR.*
