Briley 2 shot Shotgun Magazine Extension Add-On

Add more capacity to your favorite magazine extension. All it requires is to remove the end cap of your existing magazine extension, screw on the spacer and then screw the end cap onto the end of the spacer. Your existing magazine spring should still function with this spacer. However should the last round in the magazine fail to fully eject onto your carrier during firing we recommend replacing the spring. 

Magazine extension add-ons must be used in conjunction with our MODULAR EXTENSION kit for your specific shotgun.  These CANNOT be used independently or with factory parts . THESE ONLY FIT BRILEY MAGAZINE EXTENSIONS.  THEY DO NOT FIT FACTORY EXTENSIONS OR FOREARMS.
