Benefits of technology

This patent describes a firearm mechanism that has a bolt carrier with a cavity and a buffer with a cavity. A weight travels between the two cavities and a damping mechanism is used to control the movement of the weight. The buffer cavity has a reduction in cross-sectional size, which may be continuous or constant along its length. The shape of the buffer cavity may be constant or vary along its length. The invention provides a firearm mechanism that reduces recoil and noise during firearm use.

Problems solved by technology

While a high firing rate has certain benefits, there can be drawbacks such as decreased accuracy and increased ammunition consumption.
It has been discovered that ambient conditions and firearm accessories can impact the cycle rate of firearm action mechanisms.

Abstract

In some embodiments, a firearm mechanism comprises a bolt carrier comprising a bolt carrier cavity, a buffer comprising a buffer cavity and a weight arranged to travel between the bolt carrier cavity and the buffer cavity. The buffer cavity comprises a damping mechanism comprising a reduction in a cross-sectional size of the buffer cavity. In some embodiments, the damping mechanism and weight comprise a valve arrangement arranged to pressurize the buffer cavity and damp kinetic energy carried by the weight.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to automatic machine guns and fire control mechanisms.[0002]Automatic repeating firearms generally have high firing rates. For example, M4 and M16 machine guns can fire 700-900 or more rounds per minute. While a high firing rate has certain benefits, there can be drawbacks such as decreased accuracy and increased ammunition consumption.[0003]There remains a need for firearm mechanisms having variable rates of fire. There remains a need for novel firearm mechanisms, and a need for mechanisms that can slow the firing rate of available automatic firearms.[0004]It has been discovered that ambient conditions and firearm accessories can impact the cycle rate of firearm action mechanisms. For example, barrel muzzle attachments will often trap more heat in the action mechanism and increase firing rate. There remains a need for firearm mechanisms that are less pervious to cycle rate change due to conditions and accessories.[0005]All US ...
