This is our new version of our Byrna Fast Cap. This cap is made in a durable Carbon Fiber Nylon composite that is comparable to aluminum in strength. These caps have been thoroughly tested and perform just as well as our original cap.

These caps are designed to allow changing the Co2 cylinder on All Byrna Launcher Models without using the magazine to open the Co2 chamber. Saving time when seconds count is the purpose of these caps.

The cap has a 3/8” protrusion when installed.
