The SINCLAIR CHAMBER PLUG seals the chamber and bore to prevent solvents and oils from leaking into the action when stored upright.
It can be used to contain solvents within the barrel for deep cleaning and is effective when left overnight with the muzzle taped to avoid evaporation.
Using the plug for long-term storage can prevent rust preventative agents and oils from moving into the action and trigger group, protecting the trigger from damage.
