Abstract
Abstract A safety cap (10) having a sleeve (12) with a screen mesh (14) for slidable engagement with a gun barrel (16) to fragment an unintentionally discharged jelled paint pellet. The sleeve (12) has a longitudinal axially bore (22) sized and shaped to be slidably received over the gun barrel (16) with a tight fit. The plurality of filaments (34) on the screen mesh (14) form openings (36) that are sized and shaped to fragment the jelled paint pellet and permit all of the fragments of the jelled paint pellet to exit the gun barrel (16) to avoid plugging of the bore (18). A threadable fastener (52) can be used to secure the attachment of the safety cap (42) to the gun barrel (50).
