We are proud to introduce the newest Hyve Technologies Mag Extension to the family, the +3 mag base pad for the FN 509. Like a couple of our other extensions, this FN 509 +3 Mag extension features our snap in design that is followed up with a set screw to add extra insurance that your mag will not to slide off the back off the extension. This mag extension follows the frame perfectly and is very aesthetically pleasing, while giving you a few extra rounds!
