Abstract: A delayed blowback system for a firearm is provided. The system includes a bolt with two detent members operatively coupled within the bolt, each detent member comprising a detent. The system further includes a recoil spring guide rod having two matching recesses on opposing sides of the recoil spring guide rod, wherein the bolt and the two detent members are coupled to and slidable along the recoil spring guide rod between a firing position and a recoil position. The firing position includes the detents resting in the matching recesses on the recoil spring guide rod in response to a round being fired, the bolt moves back and pushes the detent members back, wherein by nature of a geometry of the detents and the matched recesses, the detent members outward in opposite directions and perpendicular sliding along the recoil spring guide rail in the recoil position to complete a recoil cycle.

Abstract: A lower receiver that may be right hand or left hand configurable is provided. The lower receiver includes a static ejector that can be easily configured for right hand or left hand positions within the same lower receiver and a magazine button assembly having a left magazine button and a right magazine button that are operatively coupled together so that either magazine button can be pushed to release the magazine. This allows the gun builder to use this one lower receiver to build a right or left handed rifle.

Abstract: 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.

Abstract: 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.

Abstract: 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. A buffer may be included as part of the configurable blowback bolt to shorten the stroke based on the caliber of ammunition being fired with the configurable blowback bolt system.
