Byrna 8 Gram CO2 + Oiler Cartridges | 10 Count Pack | for Byrna SD/CL/HD/EP - (9 CO2 + 1 Oiler Cylinders)

They work fine but being proprietary they overpriced them, of course.

These work great in our Byrna. However, Amazon packed the box of these absolutely loose in a bigger box with some other things. Not sure how this is safe with them tumbling around in there? But Amazon has been packing and shipping most of my items like this for a while now— no real consideration of what the items are.

Haven't used them but I'll give them a five anyway. Always good to have spares.

Had to order this box of Co2 cartridges to get one oiler cartridge. They don’t sell the oilers separately. Byrna sells an oiler kit that doesn’t need a Co2 cartridge so I’ll be getting one of those instead of ordering the cartridges. Otherwise, if one practices often enough, this cartridge kit does the job.

Very good CO2 cartridges.
