## Abstract

A receiver and a method for manufacturing it are disclosed. The receiver contains an assembly pivotally coupled with the lower receiver, a buttstock coupled with the assembly, wherein the assembly is configured to move from a locked position to a folded position and back to the locked position.

## Claims

### Claim 1

A lower receiver comprising:
a stopper movable between a blocking position and an open position, wherein the stopper prevents rearward movement of a bolt carrier when the stopper is in the blocking position, wherein the stopper allows rearward movement of the bolt carrier when the stopper is in the open position; and
a buffer assembly, wherein the buffer moves the stopper to the open position when the assembly is in a locked position.

### Claim 2 (depends on 1)

The lower receiver of claim 1 further comprising an assembly coupled with the lower receiver; wherein the assembly is configured to move from a locked position to a folded position and back to the locked position.

### Claim 3 (depends on 2)

The lower receiver of claim 2, wherein the assembly is pivotally coupled with an upwardly extending lobe.

### Claim 4 (depends on 3)

The lower receiver of claim 3, wherein the upwardly extending lobe is integral with the lower receiver.

### Claim 5 (depends on 1)

The lower receiver of claim 1, wherein the buffer assembly abuts the stopper when the assembly is in the locked position.
