Byrna’s all new quick release cap, now allows you to change CO2 cartridges without the use of the magazines built in hex key. The knurled surface allows both the installation or removal of even a partially filled CO2 cartridge with only your fingers.

They're made so well, the design makes it so easy to remove the CO2 cartridge quick and easily. Great quality and of course the cool logo!

Quick release cap for CL model.
This is a MUST for all CL owners. The magazine tool is very questionable and fails to work MUCH of the time. The knurled quick release is perfect.
