Byrna 25 round drum MaG KiT

The B25 Drum Kit attaches to your existing Byrna 5 round magazine and makes it into a Drum that cann hold 20-25 rounds! It can feed both chemical and kinetic rounds of many different weights.

The B25 can use a variety of kinetic ammo weights from 3g to 10g+ as well as chemcial ammo. If you plan to use chemical rounds we recommend the chemical ammo called "Kinetix" produced by Grimburg Less Lethal. See HERE.

The B25 Drum Kit is easy to install. Just follow the included instructions or follow along with the assembly video. Basically you disassemble your Byrna 5 round magazine, add in a stopper magnet and holder washers to keep it in place, and then press the magazine onto the adapter. From there you determine what springs you want to use based on your ammo type and drop them in followed by the magnetic 'followers'. Then you just cram your ammo in from the top. 

With hundreds of kits sold, the B25 started off as a joke and has quickly become a top seller. The Byrna LE with it's 12g co2 cart allows you to get a full drum worth of shots. The SD and models that use 8g co2 will get about half the drum worth of shots. I recommend those models use the 12 g adapters to get full power through the whole mag.
