Firearm attachment assembly, member for attaching and method of securing

Abstract

A firearm attachment assembly is provided. The firearm attachment assembly includes an upper mounting portion and a lower mounting portion. Each portion has an inner surface. Also, the firearm attachment assembly includes a layer affixed to and covering at least a portion of the inner surface of the upper mounting portion and at least a portion of the inner surface of the lower mounting portion. A member and a method of attaching the firearm attachment assembly is also provided.

1 . A firearm attachment assembly, comprising:
 an upper mounting portion;   a lower mounting portion attached to the upper mounting portion, wherein the upper mounting portion and the lower mounting portion each have an inner surface; and   a layer affixed to and covering at least a portion of the inner surface of the upper mounting portion and at least a portion of the inner surface of the lower mounting portion.   
     
     
         2 . The assembly defined by  claim 1 , wherein the layer is permanently affixed to the inner surface of the upper mounting portion and the inner surface of the lower mounting portion. 
     
     
         3 . The assembly defined by  claim 1 , wherein the layer comprises a composite material. 
     
     
         4 . The assembly defined by  claim 1 , wherein the layer has a hardness which is less than the hardness of the upper mounting portion and the lower mounting portion. 
     
     
         5 . The assembly defined by  claim 1 , wherein the layer is elastomeric. 
     
     
         6 . The assembly defined by  claim 1 , wherein the layer is thermoplastic. 
     
     
         7 . The assembly defined by  claim 1 , wherein the upper mounting portion and the lower mounting portion each comprise nylon and carbon fibers. 
     
     
         8 . The assembly defined by  claim 1 , wherein the upper mounting portion and the lower mounting portion each comprise nylon and glass. 
     
     
         9 . The assembly defined by  claim 2 , wherein the layer comprises a portion which is disposed between the inner surface and an outer surface of the lower mounting portion. 
     
     
         10 . The assembly defined by  claim 2 , wherein the layer is separately interlocked with the upper mounting portion and the lower mounting portion. 
     
     
         11 . The assembly defined by  claim 1 , further comprising a first leg attached to the lower mounting portion and a second leg opposing the first leg and attached to the lower mounting portion. 
     
     
         12 . The assembly defined by  claim 11 , wherein the lower mounting portion comprises a first receiving portion and the first leg comprises a pin portion attached to the first receiving portion. 
     
     
         13 . The assembly defined by  claim 11 , wherein the second leg is formed in a unitary manner with the lower mounting portion. 
     
     
         14 . The assembly defined by  claim 11 , further comprising a member transversely disposed through the lower mounting portion. 
     
     
         15 . The assembly defined by  claim 11 , wherein the first and second leg are formed in a unitary manner with the lower mounting portion. 
     
     
         16 . The assembly defined by  claim 12 , wherein the lower mounting portion further comprises a second receiving portion and the second leg comprises a pin portion attached to the second receiving portion. 
     
     
         17 . A member for a firearm attachment assembly, comprising:
 a portion which tapers from a first end to a middle portion; and   a threaded portion attached to the middle portion.   
     
     
         18 . A method for securing an attachment assembly to a weapon, comprising:
 providing an attachment assembly comprising a passage formed there through;   positioning the attachment assembly over a slot in a rail such that the passage is aligned with the slot; and   inserting a member into the passage and between opposite sides of the slot to secure the attachment assembly to the rail.   
     
     
         19 . The method defined by  claim 18 , wherein the attachment assembly further comprises a lower mounting portion having a first leg and a second leg and wherein the passage is formed through the first leg and second leg. 
     
     
         20 . The method defined by  claim 19 , further comprising rotating the first leg about an axis to position the first leg adjacent the rail such that the first leg is separated from the second leg by the rail.
