Recoil system and method for upper receiver
DCFirst Claim
1. A direct gas impingement modular rifle system comprising:
- a lower receiver assembly;
an upper receiver assembly containing a bolt carrier;
a housing contained within the upper receiver assembly, the housing enclosing a recoil spring and a rod;
wherein the housing is mounted on the bolt carrier, wherein a top face of the bolt carrier has integrated receptacle compartments, the integrated receptacle compartments allowing for the housing to rest upon the bolt carrier inside the upper receiver assembly; and
wherein the housing contains;
a counter bore shoulder against which the recoil spring rests; and
a hole in the front of the housing through which the rod protrudes.

Abstract
In embodiments, a modular rifle includes a lower receiver assembly, an upper receiver assembly, and a coupling mechanism. The upper receiver contains a bolt carrier and a housing enclosing the recoil spring and rod. Within the housing is a counter bore shoulder against which the recoil spring rests. Integrated into the top face of the bolt carrier are compartments, upon which the housing is mounted. Holes in the front of the housing and the upper receiver assembly accommodate the rod. Containing the recoil spring and rod within in the housing mounted to the bolt carrier allows the modular rifle to have a folding, collapsible, or otherwise non-fixed stock. Attached to the rod is a retaining tab, the depression of which allows for the release of the upper receiver from the lower receiver for disassembly of the rifle.
