Firearm handguard assembly

Abstract

A firearm handguard assembly system is disclosed. The system comprises a handguard including at least four apertures, a barrel nut having a first threaded end and a second smooth end, the threaded end coupled to the handguard, and an index block including at least four apertures, the index block coupled to the handguard by at least four screws, each screw having a head and a tip, the tip threaded through: one of the at least four apertures on the index block, and one of the at least four apertures on the handguard.

What is claimed is: 
     
         1 . A firearm handguard assembly system, the system comprising:
 a handguard including at least four apertures;   a barrel nut having a first threaded end and a second smooth end, the threaded end coupled to the handguard; and   an index block including at least four apertures, the index block coupled to the handguard by at least four screws, each screw having a head and a tip, the tip threaded through: one of the at least four apertures on the index block, and one of the at least four apertures on the handguard.   
     
     
         2 . The system of  claim 1 , wherein the barrel nut further comprises: a groove between a first lip on the first threaded end and a second lip on the second smooth end. 
     
     
         3 . The system of  claim 2 , wherein the index block further comprises one or more feet. 
     
     
         4 . The system of  claim 3 , wherein the one or more feet of the index block interfaces with the groove of the barrel nut between the first lip and the second lip. 
     
     
         5 . The system of  claim 1 , wherein the firearm handguard assembly system further includes a gas tube. 
     
     
         6 . The system of  claim 5 , wherein the threading of the screws produces a residual force around the gas tube. 
     
     
         7 . The system of  claim 5 , wherein the threading of the screws produces a residual force under the gas tube. 
     
     
         8 . The system of  claim 1 , wherein the handguard is comprised of magnesium. 
     
     
         9 . The system of  claim 1 , wherein the handguard contains a picatinny rail. 
     
     
         10 . The system of  claim 1 , wherein the handguard contains keymod holes. 
     
     
         11 . A firearm comprising:
 an upper receiver;   a handguard including at least four apertures; and   a handguard assembly system for mounting the handguard to the upper receiver, the handguard assembly system comprising:
 a barrel nut having a first threaded end and a second smooth end, the threaded end coupled to the handguard, and 
 an index block including at least four apertures, the index block coupled to the handguard by at least four screws, each screw having a head and a tip, the tip threaded through: one of the at least four apertures on the index block, and one of the at least four apertures on the handguard. 
   
     
     
         12 . The firearm of  claim 11 , wherein the barrel nut further comprises: a groove between a first lip on the first threaded end and a second lip on the second smooth end. 
     
     
         13 . The firearm of  claim 12 , wherein the index block further comprises one or more feet. 
     
     
         14 . The firearm of  claim 13 , wherein the one or more feet of the index block interfaces with the groove of the barrel nut between the first lip and the second lip. 
     
     
         15 . The firearm of  claim 11 , wherein the firearm handguard assembly system further includes a gas tube. 
     
     
         16 . The firearm of  claim 15 , wherein the threading of the screws produces a residual force around the gas tube. 
     
     
         17 . The firearm of  claim 15 , wherein the threading of the screws produces a residual force under the gas tube. 
     
     
         18 . The firearm of  claim 11 , wherein the handguard is comprised of magnesium. 
     
     
         19 . The firearm of  claim 11 , wherein the handguard contains a picatinny rail. 
     
     
         20 . The firearm of  claim 11 , wherein the handguard contains keymod holes.
