I bought the Fast Cap Adapter for my Byrna SDXL launcher and I am very happy with it. It makes changing the CO2 cartridge so much easier and faster than using the factory cap and the magazine tool. I can just twist the cap by hand and replace the cartridge in seconds. No more fumbling with the tool or worrying about losing it. The Fast Cap Adapter is also compatible with the Byrna Boost Adaptor (XL), which allows me to use 12 gram CO2 cartridges instead of 8 gram ones. This gives me more shots per cartridge and more convenience, as 12 gram CO2 cartridges are widely available everywhere. The Fast Cap Adapter is made of stainless steel and has a polished finish. It looks great and feels sturdy. It fits snugly on the CO2 chamber and does not leak or rattle. It is easy to install and remove, and does not damage the launcher or the cartridge. I highly recommend the Fast Cap Adapter to anyone who owns a Byrna SD, EP or HD launcher. It is a great accessory that improves the performance and usability of the launcher. It is worth every penny and I am very satisfied with it.

Unfortunately the wrong finish was sent to me. The listing has the finish as matte black, however the item sent was unfinished aluminum. Disappointing, as this does not match the rest of the Byrna. That said, it does fit.

Works great, fast and easy to unscrew and replace CO2 cartridge. My Kydex IWB holster needed a slight mod for the extended length but that was fairly easy.
