Rifle vented upper receiver

Abstract

Methods for directing a casing are provided. The method can include firing a firearm. The firearm can comprise an upper receiver having a bore disposed therein. The bore can extend along a longitudinal axis of the upper receiver. The upper receiver can also include an ejection port disposed through a first side of the upper receiver. The upper receiver can also include a deflector extending from the upper receiver at a first end of the ejection port. The deflector can be designed to direct the casing in a forward direction.

1 - 3 . (canceled) 
     
     
         4 . An upper receiver, comprising:
 a bore extending along a longitudinal axis of the upper receiver;   an ejection port disposed through a first side of the upper receiver; and   one or more vents disposed through the first side of the upper receiver.   
     
     
         5 . The upper receiver of  claim 4 , further comprising one or more vents disposed through a second side of the upper receiver. 
     
     
         6 . The upper receiver of  claim 5 , wherein the one or more vents are elongated in shape and extend generally from a top side of the upper receiver toward a bottom side of the upper receiver. 
     
     
         7 . The upper receiver of  claim 5 , wherein three or more vents are disposed through each of the first side and a second side of the upper receiver. 
     
     
         8 . The upper receiver of  claim 4 , wherein at least one of the one or more vents is disposed behind the ejection port. 
     
     
         9 . The upper receiver of  claim 4 , further comprising a deflector having a curved contact surface. 
     
     
         10 . An upper receiver, comprising:
 a bore extending along a longitudinal axis of the upper receiver;   an ejection port disposed through a first side of the upper receiver;   a deflector having a curved contact surface; and   one or more vents disposed through a first side and a second side of the upper receiver.   
     
     
         11 . The upper receiver of  claim 10 , wherein the deflector extends from a section of the first side that is about three fourths the height of the first side of the upper receiver and wherein the deflector has five or more surfaces. 
     
     
         12 . The upper receiver of  claim 10 , further comprising two lower receiver connectors configured to connect the upper receiver to a lower receiver, each having a takedown pin. 
     
     
         13 . The upper receiver of  claim 10 , wherein at least one of the one or more vents is disposed through the first side behind the ejection port. 
     
     
         14 . A method for directing a casing, comprising:
 firing a firearm, wherein the firearm comprises:
 an upper receiver having a bore disposed therein, wherein the bore extends along a longitudinal axis of the upper receiver; 
 one or more vents disposed through the first side of the upper receiver; and 
 an ejection port disposed through a first side of the upper receiver, wherein a deflector extends from the ejection port and directs a casing in a forward direction. 
   
     
     
         15 . The method of  claim 14 , wherein the deflector directs a casing forward along a path about 15 degrees to about 60 degrees from the longitudinal axis of the upper receiver. 
     
     
         16 . The method of  claim 14 , wherein the deflector directs a casing forward along a path about 30 degrees to about 60 degrees from the longitudinal axis of the upper receiver. 
     
     
         17 . The method of  claim 14 , wherein the deflector directs a casing forward along a path about 45 degrees from the longitudinal axis of the upper receiver. 
     
     
         18 . The method of  claim 17 , wherein the deflector has a contact surface with an elliptical shape having a radius greater than the first end of the ejection port.
