I purchased the Mission 4 rifle
Make sure that you follow the manufacturers storing instructions for the Mission 4 rifle. It is different than the pistol. Incorrect storage will result in drainage of the CO2 cartridge.

The Mission 4 rifle does not have the same puncture technology as our Pistols and TCR Rifle. Byrna does not claim that the Mission 4 has this technology. Even though it does not have the puncture technology that is activated by a trigger pull, there is still an easy way to store the rifle ready for fast deployment. While tightening the cartridge, it should turn very easily with very little pressure. Very lightly tighten the CO2 cartridge until it begins to get harder to turn and immediately stop. As soon as it stopped turning, the cartridge is pressed up against the pin that punctures the cartridge. At this point, install the stock upside down, 180 degrees from the normal position with stock pointing up. Cock the launcher, insert the magazine, and ensure the air valve is in the on position. The launcher is now ready to store for self defense. To use the launcher, grab the stock and twist it clockwise 1 and a half turns so the stock is now in the normal position. This will puncture the CO2. Then put the safety selector in the fire position and pull the trigger to shoot the launcher.
