Abstract: A precision targeting system for a firearm has an image capturing scope, a processor, and an actuator. In one embodiment, a user indicates when he wants to lock onto the target, and then readjust his aim after receiving feedback from the system. In another embodiment, the system automatically locks onto the target. After lock on, the system compares successive images, and determines if the target has moved in the firearm sight. If movement has occurred, the system calculates the degree of the movement, and sends appropriate signals to an actuator which corrects the aim of the firearm. The system thereby converts reasonably good aim into precision aim.

Abstract: A firearm apparatus and a method of firing ammunition therefrom, where the method utilizes a barrel (12) having a breech end surface (40) and immovably affixed to frame (10), a stand pressure surface (32), and a cartridge container (16) with a cartridge case (26) therein and countermass main body (18) movable in opposite directions. Gas from a deflagrating propellant moves the movable members and applies directionally opposite forces upon the breech end surface (40) and the stand pressure surface (32), which results in the force cancellation and ensures that the barrel (12) remains stable during firing. This solves the problem of the angle of departure and contributes to a high accuracy of shooting.

Abstract: A magazine for a firearm having a magazine well has a body with the chamber for receiving ammunition. The body has an upper opening to the chamber, and has a contact portion with adjustable screws that contact a surface in the magazine well. Adjustment of the screws is used to establish a precise selected position of the magazine with respect to the receiver, permitting adjustment of the feed height, feed angle and ejector position. Four screws are provided, one at each corner of the upper surface of the magazine.

Abstract: A paintball marker has an inline cylinder that includes a gas governor that reduces gas flow from a compressed gas source to a valve area when the bolt is in a firing position; this increases efficiency in the marker because only the required air is used to fire the paintball. This bolt operates independent of the valve pin, which increases cycle speed and enables the governor to open and close at an optimum time in the firing cycle. Further, when the bolt/piston is recocking, the gap between the valve pin and governor valve pin enables low pressure gas driving the piston to start pressurizing the cylinder and driving the piston rearwards without resistance from the high pressure gas. The marker also allows a user to remove the inline cylinder without the use of tools, and gives the user a convenient carrying handle for holding the paintball marker, which is commonly called a “snatch grip.
