| 61 | Folding stock adaptor for military-style assault rifles and a method for its use | US15665045 | 2017-07-31 | US10113832B2 | 2018-10-30 | Zachary Law |
| The present folding stock adapter can be used with many types of military-type assault rifles that typically comprise a receiver extension, buffer and action spring. The present folding stock adapter can be used to add a folding capability to a standard stock allowing it to fold against a rifle's receiver when the weapon is not in use, thus reducing the overall length of the weapon. This reduction in length can facilitate its maneuverability, storage and transport in cramped quarters. The present device can also allow for the quick unfolding of the stock in order to allow the weapon to function and be fire normally. | ||||||

| 68 | Gun Barrel Optimized for Supersonic Projectiles | US14733999 | 2015-06-09 | US20160363403A1 | 2016-12-15 | Don Duane Kopecky |
| This patent is for an apparatus which increases the muzzle velocity and energy of a supersonic projectile for a given set of ballistic conditions. When a projectile is fired from a barrel, there is typically a great deal of available energy still remaining in the combustion gas. This energy is released from the muzzle without being used when the projectile exits. Friction between the barrel and projectile, and the length, cost, and weight of the barrel limit the amount of energy which can be transferred into the projectile. This apparatus may constitute an attachment to the end of a pistol, rifle, or other gun; it may be a modification to the barrel of a gun; or it may be incorporated into an entirely new barrel for a gun.The apparatus consists of a non-contact section, and a diverging section followed by a straight, constant area section, and optionally followed by a short converging section. The apparatus works by providing the optimal geometry for the air in front of the projectile to exceed sonic velocity. The sonic shock wave is then moved out in front of the device, which reduces the air pressure at the front of the projectile and increases its acceleration. Additionally, as the projectile enters the device it loses physical contact with the walls so friction is eliminated. With a supersonic projectile, the combustion gas behind it must travel at supersonic speed to move around and past the projectile and this produces very large wave drag. So even though there is not a tight seal between the projectile and the wall, the expanding gas still exerts considerable accelerating force on the projectile. Also, the gas that does flow around the projectile produces a hypersonic jet of air exiting the device ahead of the projectile, in effect blazing a trail through the air for the projectile to follow.Furthermore, in the non-contact section the wall friction is negligible while the fluid friction is significant which causes the projectile to absorb more available energy from the propellant. | ||||||

| A folding pistol is balanced so that it is held making three points of contact with the user's hand, resulting in more stability when discharged. When held by a user, the invention puts the gun bore axis in close alignment to the center axis of the user's forearm; reducing barrel jump and improving accuracy. A folding rear activation arm when in the closed position mechanically blocks the hammers preventing unintentional discharge. | ||||||

| 74 | Breach lock | US13210416 | 2011-08-16 | US08474171B1 | 2013-07-02 | Alan Simmons |
| The breach lock is for use in securing open the breach of an assault rifle during cleaning of the bolt action and the breach between uses of the assault rifle. The breach lock includes a notch along a top of the breach lock and a hole along the breach lock, which define a length. The breach lock is inserted between the upper receiver assembly and the lower receiver assembly so as to prevent any rotation there between. The notch bolts to the upper receiver assembly whereas the hole employs the pin of the assault rifle to engage the lower receiver assembly. The breach lock is simple in installation and removal with use of an assault rifle, and prevents unwanted collapse between the upper and lower receiver assemblies, which would otherwise pinch or injure the hand and fingers of an end user when cleaning. | ||||||
