An improved receiver such as for bolt action firearms has an integrally formed reinforcing feature or blade situated below the ejection port. This blade extends longitudinally from the proximal receiver bridge to the distal receiver bridge and may continue into the barrel boss region. Functioning like an arch bridge, the reinforcing blade significantly enhances the structural rigidity of the bolt receiver at its weakest point around the ejection port, reducing flexion during firing and minimizing fatigue. The blade tapers in thickness both laterally away from the receiver's centerline and longitudinally toward the distal end, optimizing material usage while maximizing structural benefits. The bolt receiver is preferably fabricated as a single, monolithic structure using metal 3D printing technology, which allows for the integral formation of additional features such as a Picatinny rail on the top surface and a recoil lug at the distal end portion. These integrated components collectively improve the receiver's functionality, durability, and versatility.

To allow a reflex sight to be mounted to the slider of a handgun and removed without the need for tools, an adapter shoe may be secured to the slider to provide an interface between an optics-ready recess of the slider and a mounting element that forms part of the reflex sight assembly. The adapter shoe may provide a dovetail track that engages complementary dovetail features of the mounting element. A push button retention mechanism may be biased to lock the mounting element within the adapter shoe. Actuation of the push buttons may retract the retention mechanism and allow the reflex sight assembly to slide out of the dovetail track.

A sight and accessory mount assembly for a firearm having a rail includes a sight mount configured to carry a sight, and an accessory mount configured to carry an accessory. The accessory mount extends rearwardly from, and is pivotally connected to, the sight mount when the sight and accessory mount is attached to the firearm rail. The accessory mount is rotatable between a first end position and a second end position relative to the first sight mount, wherein in the first end position the accessory mount and an accessory that may be carried by the accessory mount are aligned with the sight mount and a sight that may be carried by the sight mount, and in the second end position the accessory mount and an accessory that may be carried by the accessory mount are pivoted away from the sight mount.

A linear shaped charge electro-explosive (LSCe) device integrates an initiator and booster charge on the backside of a main charge and solid V-shaped liner. The initiator is responsive to an electric stimulus to produce a shockwave that detonates and propagates through the booster charge to magnify the shockwave, which in turn detonates and propagates the main charge to further magnify the shockwave that collapses the solid V-shaped liner and projects forward a shaped charge jet. A wave shaper may be positioned in the booster or main charge to flatten the wave front into an approximately planar wave front when the magnified shockwave interacts with the V-shaped liner. The wave shaper and main charge and possibly all components energetic and non-energetic, except the initiator, may be formed using additive manufacturing. Alternately, only non-energetic components may be formed using additive manufacturing. The device may be formed into a linear, are or ring-shaped form factor. Additive manufacturing enables device scaling and optimal device function resulting in enhanced shaped jet output beyond those of traditional LSCs.

A device may include a set of payloads and a mechanism. The set of payloads may be configured to interact with at least one of an airborne device or a component of the airborne device via at least one of physical entanglement, sensor obscuration, or surface adhesion. The mechanism may be operable between an inactive state and an active state. The mechanism may be configured to transition to the active state in response to inductive energy generated by relative motion through a magnetic field during launch, and deploy the set of payloads based on at least one of one or more elapsed times during travel of the device along the trajectory, one or more positions of the device along the trajectory, or one or more distances traveled by the device along the trajectory.
