Patent number: 10274278Abstract: Various embodiments are provided to implement an attachment for a firearm that operates as a flash hider, a muzzle brake, and/or to mount, e.g., a sound suppressor, to the firearm. In one example, a firearm attachment includes a base adapted to couple to a muzzle end of a barrel of a firearm. The firearm attachment includes a plurality of longitudinal tines that extend forward from the base. The base includes a plurality of apertures disposed rearward of the tines and that extend from a bore within the base through an outer circumfery of the firearm attachment. The apertures exhibit a first diameter at the bore and a second larger diameter at the outer circumfery. The apertures are adapted to impart thrust to the firearm attachment in response to combustion gases passed from the bore through the apertures to compensate for muzzle rise associated with the firearm.Type: GrantFiled: January 14, 2016Date of Patent: April 30, 2019Assignee: SureFire, LLCInventors: Barry W. Dueck, Michael Voigt, Karl R. Honigmann

Patent number: 10088259Abstract: Various techniques are provided to assemble, manufacture, and operate firearm sound suppressors. In one example, a sound suppressor for a firearm includes a baffle; a spacer abutted to the baffle; and a circumferential laser weld joining the baffle and the spacer. In another example, a sound suppressor for a firearm includes a plurality of baffles; a plurality of spacers; a substantially tubular housing surrounding the baffles and the spacers; wherein the housing and the spacers define an annular volume surrounding the spacers; an aperture in a circumfery of at least one of the spacers; and wherein the aperture is adapted to direct combustion gases in a radial direction from within the spacer into the annular volume to reduce ejection port flash of the firearm. Additional suppressor embodiments and related methods are also provided.Type: GrantFiled: January 14, 2016Date of Patent: October 2, 2018Assignee: SureFire, LLCInventors: Barry W. Dueck, Dennis Radgowski, Kavan Brown, Karl R. Honigmann

Patent number: 8973481Abstract: In one example, a firearm sound suppressor includes a housing, a baffle, and an inner sleeve adapted to be disposed within the housing and to substantially surround the baffle. The inner sleeve includes a sidewall adapted to slide against the housing to permit the inner sleeve with the baffle to be selectively inserted into and removed from the housing without the baffle contacting the housing, and a longitudinal split extending through the sidewall and between front and rear ends of the inner sleeve to permit the sidewall to flex to permit removal of the baffle from the inner sleeve. Other embodiments are also contemplated.Type: GrantFiled: October 28, 2013Date of Patent: March 10, 2015Assignee: SureFire, LLCInventors: Barry W. Dueck, Karl R. Honigmann, Brooke C. Smith, John W. Matthews

Patent number: 7321175Abstract: Embodiments of the present invention relate to a linear actuator in which the play and backlash in the linear motion of a stepper motor is reduced through the use of a torsion spring coupled to the stepper motor splined shaft. Also, embodiments of the invention include a controller designed for holding in the hand or mounting to a table with a bi-directional self-zeroing control knob which controls actuator speed and displacement. A flash memory unit may be included in some embodiments in order to save position information and other information about the linear actuator when power to the linear actuator is stopped.Type: GrantFiled: January 24, 2005Date of Patent: January 22, 2008Assignee: Newport CorporationInventors: William Culpi, Thomas K.
