The BLAMM RIMX Magazine Extension is designed to give an additional five rounds of capacity to your factory ten round 22LR magazine. It requires no permanent modifications to your magazine and installs in minutes! Like our previous extension designs our clamshell design is utilized for maximum reliability and ease of installation. The extension is undercut to provide additional obstacle clearance.  Like all BLAMM Enterprises products these are 100% designed and manufactured in the USA with reliability and durability first in mind! Manufactured from strong UV resistant plastic with stainless steel hardware to handle outdoor shooting environments.
 
Standard color is black. We also offer custom color options to match your gear! Please contact us if you are looking for a color not currently offered. Please allow for up to 2 additional days for custom colors to ship.
