Abstract: A firearm accessory mounting rail with an integrated back up sight system including an elongated Picatinny rail having longitudinally spaced apart first and second end regions and a transverse profile. A first sight element has a visual marker substantially centrally positioned. A second sight element has laterally spaced apart visual markers. A substantially centered longitudinal channel extends along the upper surface of the rail between the first and second sight elements. The firearm may be sighted by visually aligning the marker of the first sight element between the markers of the second sight element, the visual alignment being at least partially through the longitudinal channel. The sight elements may be defined completely within the transverse profile of the rail so as not to interfere with the normal attachment of any accessories to the rail and may be adjustable for windage and/or elevation. The visual markers may be illuminated by light gathering fiber optic or tritium elements.

Abstract: A method for mounting a bipod support to a forearm stock of a firearm or other bipod mounted device permits a user or shooter to selectively allow panning (or altering the aim point along an azimuth), tilting (or altering the orientation of a device relative to a horizontal line) and canting (or orienting a device at a selected rotational orientation relative to an axis of rotation). The bipod support includes lockable controls for selectively limiting panning, tilting and canting in a manner which lets the shooter or user easily respond to changing situations when in the field.

Abstract: A gravity deploying bi-pod leg set is provided which automatically locks into position when fully deployed by a gravity slide lock.

Abstract: A sub-caliber bullet with an aerodynamic shape has long-range accuracy due to a high muzzle velocity and reduced time of flight to a target. The bullet has a forward portion, a mid-portion and an aft portion. The forward portion has a density in excess of 10/cm3 while the mid-portion has a lower density. The bullet has an aspect ratio of at least 5:1 and a diameter, d, that satisfies a Power Law equation: d=D*(x/L)n where D is a maximum bullet diameter, L is the length, x is a distance rearward from a nose of the bullet and n is a Power Law exponent that is between 0.5 and 0.75. In some embodiments, a blind bore extends into the mid-portion from the aft portion and a sustainer propellant within the blind bore ignites as the bullet exits a gun muzzle to provide a velocity boost and to overcome aerodynamic drag.

Abstract: The present invention's stratified composite material system of armor, as typically embodied, comprises a strike stratum and a backing stratum. The strike stratum includes elastomeric matrix material and inventive ceramic-inclusive elements embedded therein and arranged (e.g., in one or more rows and one or more columns) along a geometric plane corresponding to the front (initial strike) surface of the strike stratum. More rigid than the strike stratum, the backing stratum is constituted by, e.g., metallic (metal or metal alloy) material or fiber-reinforced polymeric matrix material. Some inventive embodiments also comprise a spall-containment stratum fronting the strike stratum. The inventive ceramic-inclusive elements geometrically describe any of various inventive modes, including: first mode, having a flat front face and a textured back face; second mode, having a pyramidal front section and a prismatoidal (especially, prismoidal, e.g.

Abstract: A rifle recoil absorbing strap assembly for absorbing rifle recoil from a rifle, the strap assembly preventing the bruising of a shoulder when firing the rifle and without having to permanently mount the strap assembly on a target shooting bench, a table or a horizontal support member. The strap assembly includes an elongated, flexible, horizontal first strap member with adjustable and releasable fastener. The adjustable and releasable fastener is used for securing together a first end and a second end of the first strap member. Also, the strap assembly includes a flexible, vertical second strap member with a first end and an opposite second end. The first and second end of the second strap member are adapted for receipt around a front portion of the rifle and secured thereto for preventing upward movement of the rifle when firing. Further, the strap assembly includes a rifle butt cradle adapted for receiving and securing a rifle butt of the rifle therein.

Abstract: According to the present invention there is provided an armor array for protecting a body to be protected from an incoming projectile having an anticipated impact direction. The armor array is constituted by at least a first and a second armor cassette, each comprising a top base plate and a bottom base plate sandwiching therebetween an expandable layer. The first and second armor cassettes are spaced apart by an intermediate depressible panel having a top and a bottom face, such that the bottom base plate of the first armor cassette faces the top face of the intermediate depressible panel and the top base plate of the second cassette faces the bottom face of the intermediate depressible panel. The armor array is constructed such that upon expansion of the expandable layer, caused by the impact of the incoming projectile, at least one of the bottom base plate of the first armor cassette and the top base plate of the second armor cassette is urged towards the intermediate depressible panel and depresses it.

Abstract: A pulse detonation wave engine (PDWE) detonation system provides for optical ignition. The detonation system has a plurality of detonation banks, where each detonation bank has a plurality of detonation chambers for receiving a fuel/oxidizer mixture from a propellant source. An optical ignition subsystem generates a plurality of optical pulses. The detonation system also has an optical transport subsystem for transporting the optical pulses from the ignition subsystem to the chambers, where the optical pulses ignite each fuel/oxidizer mixture such that the chambers detonate in a desired order. This allows the banks to be sequentially detonated and the chambers within each bank to be simultaneously detonated, without the increased tankage and toxic ignition associated with conventional approaches.
