Gas-operated guns with demountable and interchangeable barrel sections and improved actuation cylinder construction

Abstract

Gas-operated automatic and semi-automatic guns are improved by having a bisectional barrel with demountable and interchangeable muzzle sections wherein the breech section has a rifled bore and by having an actuation cylinder mounted to the receiver instead of the barrel. The muzzle sections are connected to the breech section via a tapered plug that locks into a tapered socket of the breech section. A port in the tapered plug joins with a port in the tapered socket to deliver gas from the barrel bore to the actuation cylinder and the tapered plug port in each interchangeable muzzle section is sized to provide automatic control of the proper amount of gas to cause the gun to function at its best rate based on the ammunition, silencer and length of the particular muzzle section selected by the user.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] This invention relates broadly to gas-operated automatic and semi-automatic guns, especially rifles. More particularly, it concerns such guns that comprise (a) a bisectional barrel with demountable and interchangeable muzzle sections and (b) an actuation cylinder mounted to the receiver instead of the barrel. [0003] 2. Description of the Prior Art [0004] There is a recognized need for guns that can easily change barrel length and that can facilitate the use of non-standard ammunitions in battle conditions. This invention provides improvements in gun construction that supply these needs with greater weapon reliability and adaptability than has been attainable with prior known guns. [0005] It is known to construct guns with bisectional barrels in which the breech section bore is smooth and the muzzle section bore is rifled. Thus, U.S. Pat. Nos. 4,546,564 and 4,660,312 disclose such bisectional barrels in which the rea...

AI Technical Summary

Benefits of technology

"The invention is a new type of gun that has improved performance and accuracy. It has a unique design with a bisectional barrel that can be joined with different muzzle sections to achieve different velocities and flight patterns for projectiles. The gun also has a flexible tube that isolates the barrel from the mechanical system, keeping it clean and reliable. The actuation cylinder is directly mounted to the receiver, improving the gun's function and reliability. The invention also provides a method for mounting the barrel to the receiver, keeping it as a separate entity and improving accuracy. Overall, the invention provides a new level of performance and accuracy for guns."

Problems solved by technology

This load on the barrel results in unwanted barrel movement at the time the projectile leaves the muzzle causing serious dispersion of the resulting shots.

The drawback to the M16 design is that it dumps that gas directly into the working mechanism that has historically been a detriment to reliable functioning.
