The Byrna SD runs on 8 gram CO2 out of the box, which does the job but limits how many shots you get before a reload. The Byrna SD Boost 12g CO2 Adapter changes that. It replaces the standard CO2 housing with a chamber built to accept the larger, far more common 12 gram cartridge format, pushing your shot capacity up to around 30 rounds per fill. That is roughly a 50 percent increase over the stock setup, which adds up fast during a range session or a day of practice.
The idea here is simple. More gas in the chamber means more shots before you swap cartridges. Beyond the capacity gain, there is a real convenience factor. 12 gram CO2 cartridges are stocked at sporting goods stores, paintball shops, and all over online, so finding refills is never a hassle. One thing worth noting straight from Byrna: steer clear of Crosman brand 12 gram cartridges, since they may not puncture correctly in this system. Stick with standard quality cartridges and you are good to go.
This is a hands-on upgrade, but not a complicated one. The kit comes with everything you need, including both adapter halves, two hex keys, the mounting screws and nuts, and the CO2 tube. No gunsmithing, no special tools, just follow the steps and you are set. Owners consistently call out how clean the fitment is and how straightforward the install goes, with the adapter seating onto the launcher nicely once assembled.
If you train regularly with your SD or just want fewer interruptions reloading, this is one of the more practical upgrades you can make. It keeps the launcher doing exactly what it did before, only now you are feeding it the cheaper, easier-to-find 12 gram cartridges and getting more trigger time out of each one.
It converts your Byrna SD from the standard 8 gram CO2 cartridge over to the larger 12 gram format. That bumps your shot capacity up to around 30 rounds per cartridge, roughly 50 percent more than the stock setup. The 12 gram cartridges are also easier to find and cheaper to stock up on.
Not at all. The kit includes both adapter halves, the hex keys, screws, nuts, and the CO2 tube, so you have everything needed in the box. No gunsmithing is required, and owners regularly mention how clean the fit is once it is on.
Standard, widely available 12 gram CO2 cartridges work great, and you can find them at sporting goods stores, paintball shops, and online. Byrna specifically recommends avoiding Crosman brand 12 gram cartridges, since they may not puncture correctly in this system.
This SD Boost version is set up for the Byrna SD. Byrna offers separate Boost adapters matched to other launchers in their lineup, so if you are running a different model, check that you are grabbing the right one for your launcher.
