Patent number: 9574843Abstract: An apparatus for correcting trajectories variations of projectiles launched from a firearm is disclosed. The apparatus includes a control circuit for determining an appropriate impulse to be imparted into a projectile based on the measured velocity of the projectile, at least one steering coil, and a pulsed-power supply for discharging an amount of energy commensurate with the determined impulse to the steering coil such that a set of magnetic fields is produced to impart an amount of corrective kinetic energy into the projectile as the projectile passes the steering coil.Type: GrantFiled: February 27, 2014Date of Patent: February 21, 2017Assignee: MAGNETOSPEED LLCInventors: Garet L. Itz, Weston D. Petersen, Alex J. Sitzman

Patent number: 9574845Abstract: A gun for propelling a projectile, such as a scent compound enclosed in an spherical shell, into a hunting environment comprises a frame housing a compressed gas reservoir in fluid communication with a trigger valve that is operatively associated with a manually-actuable trigger to momentarily open the trigger valve. A projectile barrel and a sound barrel are each in fluid communication with the compressed gas reservoir when the trigger valve is open. The sound barrel includes a pneumatic game call. The pneumatic game call is selectively removable from the sound barrel and replaceable with at least one other pneumatic game call that produces a different game call. A distal end of the projectile barrel preferably includes a plurality of scoring blades fixed therewithin, such that upon exiting the projectile barrel the shell of the projectile is scored by the scoring blades.Type: GrantFiled: February 10, 2016Date of Patent: February 21, 2017Inventors: Robert Wyne, Rosemary Corbey

Patent number: 9574846Abstract: A receiver having an integral stock connector component that extends along the receiver; two extension rod/rail apertures formed through the integral stock connector component, wherein each extension rod/rail aperture is formed so as to slidably receive an extension rod/rail extending from a buttstock, such that each extension rod/rail is slidably movable within one of the extension rod/rail apertures; wherein each extension rod/rail comprises a rod channel and two or more rod dimples/detents formed along the rod channel; and a latch that is movable between an engaged position and a disengaged position, wherein when the latch is in the engaged position, a protrusion portion urges latch elements into the rod/rail apertures a distance that seats the latch elements into the rod dimples/detents, and wherein when the latch is in the disengaged position, the protrusion portion allows the latch elements to retract from the rod dimples/detents and into the rod channels.Type: GrantFiled: March 5, 2015Date of Patent: February 21, 2017Inventors: George Huang, Jeffrey S. Cross
