WARNING – While your mongoose has a safety selector, it is a mechanical device which could fail. Never rely solely on the safety to prevent unintentional discharge. Always remove the magazine, check the chamber, and visually inspect that the firearm is unloaded before disassembly, or handing the firearm to someone else.
WARNING – It is possible that a cartridge may be in the chamber when a magazine is being removed from or inserted into your Mongoose PCC. A cartridge in the chamber will discharge when the trigger is pulled, whether a magazine is inserted or not. Never leave your firearm unattended, even when the magazine is removed. You must always verify the chamber is empty before field stripping your Mongoose for cleaning or other purposes.
Refer to the Mongoose parts terminology as needed.
