Abstract

A bayonet lug extension for AR-15 design carbine length rifles. The bayonet lug extension positions a bayonet relative to the barrel end to have the proper amount of blade available for use.

What is claimed is: 
     
         1 . A bayonet lug extension, comprising:
 a bayonet lug adapter, adapted to releaseably attach to a bayonet lug on a rifle; and   a bayonet receiver lug, adapted to releaseably attach to a bayonet lug groove defined in an end of a bayonet handle; wherein said bayonet lug adapter and said bayonet receiver lug are spaced apart on said bayonet lug extension such that a support ring on said bayonet handle may be received in a flash suppressor of said rifle.   
     
     
         2 . The bayonet lug extension of  claim 1 , wherein said bayonet lug adapter further comprises a latch plate pivotally attached to said bayonet lug adapter, wherein said latch plate is releaseably engageable with a bayonet lug slot on said bayonet lug. 
     
     
         3 . The bayonet lug extension of  claim 2 , wherein said latch plate further comprises a protrusion releaseably engageable with said bayonet lug slot. 
     
     
         4 . The bayonet lug extension of  claim 3 , wherein said bayonet lug adapter further comprises a spring, wherein said spring biases said latch plate protrusion for engagement in said bayonet lug slot. 
     
     
         5 . The bayonet lug extension of  claim 1 , wherein said bayonet lug adapter further comprises a substantially T-shaped slot, wherein said T-shaped slot is adapted to receive said bayonet lug. 
     
     
         6 . The bayonet lug extension of  claim 1 , further comprising a spacer interposed between said bayonet lug adapter and said bayonet receiver lug. 
     
     
         7 . The bayonet lug extension of  claim 1 , wherein said bayonet lug adapter, said bayonet receiver lug and said extension spacer comprise a unitary body. 
     
     
         8 . A bayonet lug extension comprising:
 a bayonet lug adapter, comprising a T-shaped slot defined in a top surface of said bayonet lug adapter, a slot defined in an outer lateral surface of said bayonet lug adapter, and a latch plate pivotally received in said slot;   an extension spacer, operatively connecting said bayonet lug adapter with a bayonet receiver bracket, wherein said bayonet receiver bracket comprises a bayonet receiver lug adapted to receive attachment of an end of a bayonet handle.   
     
     
         9 . The bayonet lug extension of  claim 8 , wherein said latch plate further comprises a protrusion at a top end of said latch plate, wherein said protrusion is selectively positioned between a latched state and a released state, wherein in said latched state said protrusions extend into said T-shaped slot, and wherein in said released state said protrusions are withdrawn from said T-shaped slot. 
     
     
         10 . The bayonet lug extension of  claim 8 , wherein said bayonet lug adapter further comprises a spring, wherein said spring biases said protrusions in said latched state. 
     
     
         11 . The bayonet lug extension of  claim 10 , wherein said latch plate further comprises a latch plate finger grip at a bottom end of said plate, wherein pinching said finger grip positions said protrusions in said released state.
