Patent ID: 7421935

Claim:
A barrel blocking apparatus comprising: an insertion portion including: a top section, a central post attached to or mounted from an inner surface of the top section, where the central post includes: a flared end, and raised areas, a surrounding section including: a mounting groove in which the top section is mounted, a central aperture through which a narrow portion of the post passed through, a lip and an adjacent groove for engaging the end of the barrel of a paintball gun, a friction ring, a plurality of spaced apart prongs adjacent the groove and extending downward from a lower surface of the surrounding section, each prong including a groove adapted to receive the friction ring, where the top section and post are adapted to be rotated relative to the surrounding section an amount sufficient to force the raised areas of the post to engage conforming outer surfaces of the prongs and compress the frictional ring against the inner surface of the barrel with sufficient force to hold the apparatus in place and where the post is designed to apply greater force against the prongs and friction ring when struck by an inadvertently discharged paintball.
