A rifle intelligence system includes a sensor module comprising an enclosure configured to be removably secured to a firearm; a processor disposed within the module enclosure; and a plurality of sensors disposed within the module enclosure and communicatively coupled to the processor. The plurality of sensors is configured to generate shot attribute data associated with operation of the firearm and to wirelessly transmit the shot attribute data to a mobile computing device. The shot attribute data includes at least acceleration of the firearm along a bore axis and a temperature measurement of the barrel of the firearm.

The inventive technology comprises a novel thermal indicator system that incorporates one or more thermogenic compounds that may be applied to a gun component and indicate the temperature of a gun component during and after use. This novel thermal indicator system may indicate the temperature at which the gun component will cause burns, is unsafe to store, or if a pre-determined threshold temperature has been reached resulting in a loss of firing accuracy, as well as imminent, or actual component failure.

A blaster for shooting projectiles that includes a housing that defines a housing interior, and a variable velocity barrel assembly positioned in the housing interior. The variable velocity barrel assembly includes a barrel that defines a barrel axis and a barrel interior. The barrel includes an exit opening at a distal end thereof. At least a first opening communicates the barrel interior with an exterior of the barrel. The first opening is defined through a side wall of the barrel. A slider member that includes a cylindrical portion that surrounds the barrel is movable axially along the barrel between a maximum velocity position where the cylindrical portion covers the first opening and a minimum velocity position where the slider member does not cover the first opening.

An upper receiver assembly for a firearm having an upper receiver with an integral barrel nut, a handguard assembly and a barrel nut assembly with a barrel and lock nut is provided. The barrel is received by the upper receiver and is secured directly to the upper receiver using the lock nut. The upper receiver also includes an integral handguard mounting member to which the handguard assembly may be directly attached. The upper receiver assembly allows the user to attach both the barrel and handguard assemblies directly to the upper receiver, independently of one another.

A system and method for the determination of an optimal ammunition round based upon a barrel length of a given firearm and resulting ammunition. The ammunition is preferably provided in a pair of rounds for a given caliber and bullet optimized for a range of barrel lengths, wherein a user can select a preferred round for a given firearm based upon the barrel length.

A firearm training barrel for a replica gun, the gun having a slide and a magazine with a follower. The barrel includes an extended or extendable member positioned or positionable to simulate the presence of one or more pellets in the magazine, whereby the replica gun can be fired even after the magazine's follower has reached the top of the magazine.
