The BLAMM CZ 455/452 Magazine Extension is designed to give an additional two rounds of capacity to your factory CZ plastic ten round 22LR magazine (fits plastic 10rd magazines only). However, it has been found that many magazines allow for three additional rounds to be loaded and continue to feed reliably. It requires no permanent modifications to your magazine and installs in minutes! 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.
