Recoil Reducing Spring System

Abstract

A firearm comprising a receiver with a bolt carrier assembly, a buttstock having a tube shaped opening adjacent to the rear of the bolt carrier assembly, a plurality of springs having similar inside and outside diameters disposed end-to-end within the tube shaped opening, and a buffer having a small diameter body disposed inside the inner diameter of the springs and having a large diameter head disposed where the foremost spring presses against the rear of the head and the front of the head presses against the rear of the bolt carrier assembly.

The invention claimed is: 
     
         1 . A firearm comprising:
 a receiver;   a bolt carrier assembly disposed within the receiver;   a buttstock attached to the rear of the receiver, the buttstock having a generally tubular shaped opening adjacent the rear of the bolt carrier assembly;   a plurality of springs disposed within the tubular opening of the buttstock; and   a buffer having a head at one end and a body wherein the head is larger than the body where the body fits within the plurality of springs and the foremost spring rests against the rear of the head and the front of the head rests against the rear of the bolt carrier assembly.   
     
     
         2 . The firearm of  claim 1  further comprising a means of separating the springs. 
     
     
         3 . The firearm of  claim 1  wherein the plurality of springs is arranged in series. 
     
     
         4 . The firearm of  claim 1  wherein the plurality of springs have outside diameters that are less than the inside diameter of the tubular opening and where the plurality of springs have inside diameters that are greater than the outside diameter of the buffer body. 
     
     
         5 . The firearm of  claim 1  wherein two springs are disposed within the tubular opening of the buttstock in series. 
     
     
         6 . The firearm of  claim 1  wherein the firearm is any firearm within the M16 family of firearms. 
     
     
         7 . The firearm of  claim 1  wherein the firearm is an AR15. 
     
     
         8 . A firearm comprising:
 a receiver;   a bolt carrier assembly disposed within the receiver;   a buttstock attached to the rear of the receiver, the buttstock having a generally tubular shared opening adjacent the rear of the bolt carrier assembly;   a first spring disposed within the tubular opening of the buttstock;   a second spring disposed within the tubular opening of the buttstock forward of the first spring; and   a buffer having a head at one end and a body wherein the head is larger than the body where the body fits within the long spring and the short spring and where the long spring rests against the rear of the head and the front of the head rests against the rear of the bolt carrier assembly.   
     
     
         9 . The firearm of  claim 8  further comprising a means for separating the first spring from the second spring. 
     
     
         10 . The firearm of  claim 8  wherein the first and second springs are different lengths. 
     
     
         11 . The firearm of  claim 8  wherein the first spring and the second spring have outside diameters that are less than the inside diameter of the tubular opening and where the first spring and second spring have inside diameters that are greater than the outside diameter of the buffer body. 
     
     
         12 . The firearm of  claim 8  wherein the first spring and the second spring have different spring rates. 
     
     
         13 . The firearm of  claim 8  wherein the firearm is any firearm within the M16 family of firearms. 
     
     
         14 . The firearm of  claim 8  wherein the firearm is an AR15. 
     
     
         15 . A firearm comprising:
 a receiver;   a bolt carrier assembly disposed within the receiver;   a buttstock attached to the rear of the receiver, the buttstock having a generally tubular shaped opening adjacent the rear of the bolt carrier assembly;   a short spring disposed within the tubular opening of the buttstock;   a long spring disposed within the tubular opening of the buttstock forward of the short spring;   a means for separating the short spring and the long spring disposed between the short spring and the long spring; and   a buffer having a head at one end and a body wherein the head is larger than the body where the body fits within the long spring and short spring and where the long spring rests against the rear of the head and the front of the head rests against the rear of the bolt carrier assembly.   
     
     
         16 . The firearm of  claim 15  wherein the means for separating the short spring and the long spring comprises a disc shaped spacer having a concentric hole with a diameter larger than the outside diameter of the buffer body. 
     
     
         17 . The firearm of  claim 15  wherein the short spring and the long spring have outside diameters that are less than the inside diameter of the tubular opening and where the short spring and long spring have inside diameters that are greater than the outside diameter of the buffer body. 
     
     
         18 . The firearm of  claim 15  wherein the short spring and long spring have different spring rates. 
     
     
         19 . The firearm of  claim 15  wherein the firearm is any firearm within the M16 family of firearms. 
     
     
         20 . The firearm of  claim 15  wherein the firearm is an AR15.
