First Claim
Patent Images
1. A buffer tube folding mechanism, comprising:
- first and second collars hingedly attached to one another, wherein the first collar is configured to couple to a first buffer tube through a coupling mechanism and the second collar is configured to couple to a second buffer tube through the coupling mechanism, wherein the buffer tube folding mechanism is configured to permit each of the first and second buffer tubes to receive a buffer in a closed position of the buffer tube folding mechanism;
first and second closure mechanisms configured to releasably mate; and
a buffer retainer mechanism configured to partially narrow the circumference of the first collar when the first and second collar mechanisms are not mated.

Abstract
An innovative design described in this application retains the buffer and recoil spring within the folded portion of the buttstock or buffer tube so the stock can fold. There are alternative ways to retain the buffer and recoil spring within a folded buttstock. The bolt carrier is not physically attached to the buffer and recoil spring. A folding stock assembly which contains the buffer and buffer spring within the folded portion of the stock for a firearm that uses a direct gas impingement system.
