Abstract: A turret is configured to adjust a position of an alignment stage coupled to the turret. The turret can include an adjustment knob configured to be actuatable in a plurality of adjustment directions to adjust the position of the alignment stage. The turret can further include a lock configured to prevent movement of the adjustment knob in the plurality of adjustment directions. The adjustment knob can be configured to be actuatable to transition the adjustment knob between a locked state in which the lock is engaged and an unlocked state in which the lock is released. With the adjustment knob in the unlocked state, the adjustment knob is actuatable in the plurality of adjustment directions.

Abstract: A locking rail mount including a body mounted adjacent to a mounting rail and a clamp screw extending through a channel defined by the body and across the mounting rail. The clamp screw includes a screw head having a surface facing toward the mounting rail with locking elements having a surface relief geometry. At least one compression spring is positioned between the body and a rail clamp that pushes the rail clamp toward the surface of the screw head. The surface of the rail clamp includes locking elements having the surface relief geometry that are complementarily arranged with respect to the locking elements of the screw head. When the clamp screw is tightened, the locking elements of the rail clamp and screw head are aligned to lock the rail clamp and clamp screw together to prevent unintended rotation of the clamp screw.

Abstract: A rail mounting assembly for mounting an accessory to a rail of a firearm includes a base portion arranged to support the accessory. The assembly includes a lock nut receiving recess on a first side portion and a moveable clamp on a second side portion where the side portions cooperate to grip the rail. A crossbar extends between the side portions such that the crossbar is movable relative to the moveable clamp. A lock nut is threadably engageable to an end of the crossbar proximate to the first side portion and a lock plate is positioned within the lock nut receiving recess between the lock nut and a spring disk when the lock nut is threadably engaged with the crossbar. The lock nut receiving recess is shaped to prevent rotation of the lock plate while allowing rotation of the lock nut.

Abstract: A sight magnifier assembly is configured to be releasably secured to a rail feature of a firearm to be used with a sight assembly to enhance a downrange image. The sight magnifier assembly includes a base configured to be releasably secured to the rail feature of the firearm and a housing rotatably coupled to the base. The housing is configured to support sight optics used to enhance or improve the downrange image. The assembly further includes a mechanism configured to enable the rotation the housing with respect to the base between a use position in which the sight optics is configured to be used with the sight assembly and a stored position in which the sight optics is moved so that the housing and the sight magnifier assembly is nearly completely obscured from the operator by the sight assembly as viewed along a longitudinal axis.

Abstract: An optical assembly includes a housing having an interior region, a first lens disposed within the interior region of the housing, a second lens disposed within the interior region of the housing, the second lens being spaced from the first lens, a spacer disposed within the interior region of the housing between the first lens and the second lens, the spacer being fabricated from glass material, and a retention assembly configured to engage the second lens when assembled to retain the first lens, the spacer and the second lens in place. The housing may include a port providing fluid communication from an exterior of the housing to the interior region of the housing. The optical assembly further may include a filler material disposed in a space defined by an exterior surface of the spacer and an interior surface of the housing via the port.

Abstract: A sight mount for use with an electrically powered sight is provided. The sight mount includes a lower portion connectably securable to a mounting surface, an upper portion supportive of the sight and comprising electrodes connectable with sight circuitry and a central portion integrally interposed between the lower and upper portions. The central portion includes a body formed to define a cavity securably receptive of a power supply such that the power supply couples with the electrodes to power the sight.
