## Description

desertcart.com : 12 Gram Co2 Extender Adapter - Compatible with BYRNA LE/SD/HD/EP - Cartridge Boost Adaptor Accesories : Sports & Outdoors

Review: Great Add-On, Easy to Install - Awesome. Easy enough to install because the instructions were very, very clear. Happy to have the extra shot capacity per CO2 cartridge. It also fits my leather holster without need for modification. IWB Kydex holster needed slight mod but it was easy to do.
Review: Great upgrade/change to factory Byrna LE - Awesome upgrade to the Byrna LE. Even though the Byrna Le already accepts 12gr CO2 cartridges, this makes everything look much more streamlined and way better looking! The install is very easy (just follow the directions on their website) and it fits perfectly. This is how Byrna should have built the LE from the factory. Works great, easy to install, great value, looks so much better. Highly recommend!

### ⭐⭐⭐⭐⭐ Great Add-On, Easy to Install

Awesome. Easy enough to install because the instructions were very, very clear. Happy to have the extra shot capacity per CO2 cartridge. It also fits my leather holster without need for modification. IWB Kydex holster needed slight mod but it was easy to do.

### ⭐⭐⭐⭐⭐ Great upgrade/change to factory Byrna LE

### ⭐⭐⭐⭐⭐ Quality and more affordable than the competition
*by R***Y on July 23, 2024*

The quality of this 12g C02 adapter is good and it's half the price of the other competitor in the market. K20 hooked me up with this and the knurled cap that makes installing your C02 cartridge tooless. Don't question it just buy it. And it super easy to install. Follow the K20 instructions and you will have it installed in a matter of minutes.
