The M22 features a solid and reliable bolt-action system, which works a 10-shot magazine, enabling fast reloading between shots. This is particularly helpful when out hunting. Alternatively, the breech is rather wide, which assists in single shot loading. So if you want to do a spot of target shooting, that's not a problem.
A quick-fill port at the front of the cylinder enables fast refilling, and a manometer is installed so you always know how much pressure you have left.
The breech is grooved with a standard 9-11mm scope rail, and a shrouded barrel is fitted to assist in noise reduction.
