The SINCLAIR CHAMBER PLUG seals the chamber and bore to prevent solvents and oils from contaminating the action when the rifle is stored upright.
It can be used to contain solvents in heavily fouled barrels for deep cleaning and is effective when used overnight, provided the muzzle is sealed to prevent evaporation.
The plug is also useful for long-term gun storage to prevent rust preventative agents and oils from leaking into the action and trigger group, protecting against trigger damage.
