Integrated upper receiver and integrated lower receiver for the ar10 and ar15 platforms

Abstract

A lower receiver of a rifle is connected to a buffer tube of the rifle. A buttstock is formed of a frame extending around the buffer tube with a lower portion of the frame connecting to the lower receiver. An opening to the buffer tube includes a curved transition region to the top of the lower receiver. The lower receiver, frame, and buffer tube are formed monolithically of a single piece of material. A grip frame may be formed monolithically with the lower receiver. A buttstock frame may be formed monolithically with a buffer tube that defines a threaded portion for securement to an upper receiver of a rifle.

         6 . The apparatus of  claim 3 , further comprising a cheek piece secured to a portion of the frame above the buffer tube. 
     
     
         7 . The apparatus of  claim 6 , further comprising a grip frame monolithically secured to the lower receiver. 
     
     
         8 . The apparatus of  claim 1 , further comprising a first curved transition between a top of the receiver portion and the buffer tube. 
     
     
         9 . The apparatus of  claim 8 , further comprising an upper receiver secured to the lower receiver. 
     
     
         10 . The apparatus of  claim 9 , wherein the upper receiver comprises a second curved transition sized to nest within the first curved transition. 
     
     
         11 . The apparatus of  claim 9 , further comprising a scope mount monolithically formed on the upper receiver. 
     
     
         12 . The apparatus of  claim 9 , wherein the upper receiver further comprises a threaded opening at a front end thereof and sized to receive a rifle barrel. 
     
     
         13 . The apparatus of  claim 12 , further comprising:
 the rifle barrel threaded into the threaded opening;   a plurality of first rifle components mounted within the upper receiver, the first rifle components including (a) a gas block and gas tube, (b) a bolt carrier group, (c) a charging handle, (b) a forward assist, and (c) an ejection port cover;   a plurality of second rifle components mounted within the lower receiver, the second rifle components including a trigger mechanism, an ejector mechanism, and a hammer mechanism.   
     
     
         14 . An apparatus comprising:
 an upper receiver for a rifle sized to receive within itself rifle components including one or more of (a) a gas block and gas tube, (b) a bolt carrier group, (c) a charging handle, (b) a forward assist, and (c) an ejection port cover; and   a scope mount monolithically formed on the upper receiver;   wherein a forward portion of the upper receiver defines a threaded portion for receiving a rifle barrel.   
     
     
         15 . The apparatus of  claim 14 , wherein a rearward portion of the upper receiver defines a curved region for nesting with a lower receiver. 
     
     
         16 . An apparatus comprising:
 a buffer tube defining a threaded portion for securement to an upper receiver of a rifle; and   a frame monolithically formed around the buffer tube and forming a buttstock for the rifle;   wherein the frame and buffer tube are monolithically formed.   
     
     
         17 . The apparatus of  claim 16 , wherein the frame comprises a loop of material extending around the buffer tube. 
     
     
         18 . The apparatus of  claim 17 , further comprising a butt pad secured to a rear portion of the frame. 
     
     
         19 . The apparatus of  claim 18 , wherein the butt pad is adjustable. 
     
     
         20 . The apparatus of  16 , further comprising a cheek piece secured to a portion of the frame above the buffer tube, the cheek piece being adjustable.
