## Abstract

Certain embodiments described herein are directed to a folding buttstock assembly that comprises collars that can reversibly engage each other. In some instances, one or more collars may comprise a gasket to reduce the likelihood of debris entering into the components of the buttstock assembly or firearm components. In other instances, a wiper or cleaning device may be present to remove debris during operation of the weapon.

## Claims

### Claim 1

A buffer tube folding mechanism, comprising:
a first collar and a second collar hingedly attached to one another, wherein the first collar is configured to couple to a first buffer tube and the second collar is configured to couple to a second buffer tube,
wherein the first collar and the second collar are configured to releasably mate; and
a buffer retainer mechanism configured to partially narrow a circumference of the first collar when the first collar and the second collar are not mated.

### Claim 2 (depends on 1)

The buffer tube folding mechanism of claim 1, wherein the buffer retainer mechanism is configured to operate manually.

### Claim 3 (depends on 1)

The buffer tube folding mechanism of claim 1, wherein the buffer retainer mechanism is configured to operate automatically.

### Claim 4 (depends on 1)

The buffer tube folding mechanism of claim 1, wherein the first collar and the second collar are manually latched, released, or combinations thereof.

### Claim 5 (depends on 1)
