Cap for a pneumatic gun

Abstract

A cap has a body with an opening defined in one end of the body. A floor is formed in the opening and is parallel to an end wall of the body defining the opening. An annular flange perpendicularly extends from the floor in the opening. With a specific mold and a specific process, the cap can be formed with a die casting process without draft allowance. The process for forming the cap is simple and the cost for manufacturing the cap is low.

What is claimed is:  
     
         1 . A cap for a pneumatic gun comprising: 
 a body having a closed first end wall and an open second end wall;    an opening defined in the second end wall of the body and a floor defining a bottom of the opening, the floor being parallel to the second end wall of the body; and    an annular flange perpendicularly extending from the floor in the opening,    wherein the cap is without any draft allowance during a die casting process for manufacturing the cap.
