Lower receiver

Provided is a fast cycling/low recoil pistol caliber carbine assembly. The carbine assembly may include an upper receiver, a lower receiver, a feed ramp, a bolt stop, a magazine, a control mechanism comprising a control lever, a control base, a control pivot pin, and a control spring, an ejector, a gap filler member. The assembly provides last round bolt hold open, trigger finger actuated bolt release, short stroke cycle, barrel ramp, ambidextrous magazine release, and uses Glock magazines.

Carbine assembly

Provided is an attachment system for coupling a mobile computing device to an optic device. The optic device may be, but is not limited to a scope, binoculars or the like. The attachment system operates with attachment devices and mounting device with apertures that provide a means to couple a mobile computing device to the optic device in such a way that the attachment system provides a line-of-sight between a camera of the mobile computing device with the lens of the optic device. This allows the camera of the mobile computing device to capture images and video using the high power zoom functionality of the optic device and the convenience of the mobile computing device.

A configurable blowback bolt system is provided. Embodiments include a two-part configurable bolt assembly having a bolt carrier and a configurable bolt that allows for use with various calibers of ammunition, both rifle and pistol. The configurable bolt may also eject cartridges to the right or left side of the rifle by moving the extractor to one or the other side of the bolt.

An upper receiver assembly for an AR style rifle is provided. The upper receiver assembly includes an upper receiver body with a channel formed in a side of the body. Further, the assembly includes a bolt carrier operatively coupled within the upper receiver body. A bolt is coupled within the bolt carrier, wherein a cam pin is coupled to the bolt and extends through an aperture of the bolt carrier. The assembly also includes a side charger having a charging handle that extends through the channel of the upper receiver body. The side charger also includes a bolt carrier engagement member. The bolt carrier engagement member engages the bolt carrier and moves the cam pin in response to pulling the charging handle toward the butt stock of the weapon. This results in charging the rifle.
