BYRNA X-TRA ROUNDS EXTENSION 

This mag extension installs just like our well known 7 round mag extender only this unit holds 11 in the mag and one in the chamber for a total of 12 rounds ready to go. These extensions will fit all Byrna HD and SD Launchers.

We do not recommend using the “one in the chamber” method for powder projectiles. They will break. 

Our extensions are made using the latest technology and material using Fused Filament Fabrication to produce a Nylon compound that is stronger than aluminum and more resistant to bending.
