Abstract: A method for making an improved projectile 360, 460 by defining a discontinuity, groove or trough in a distal ogive section of the projectile to provide an external ballistic. effect uniforming surface feature (e.g., nose ring groove 369, 469) which makes an unsupported gap in the ogive profile that beneficially affects the flow of air over the front half of the ogive. The improved bullet's external surface discontinuity feature (369 or 469) creates effects in the flowfield that dominate any dynamic effects from bullet-to bullet manufacturing inconsistency and resultant differences in dynamic behavior.

Abstract: An aiming apparatus for a firearm has a frame, a plurality of visible and/or invisible light generators connected to the frame, with each light generator operable to propagate planar and/or non-planar light in the forward direction. Each light generator utilizes shaping optics to create straight or curved lines of light. Straight lines of light propagating in a forward direction will create a plane of light, while curved lines of light propagating in a forward direction will create non-planar light. A plurality of planar light oriented in a non-parallel, overlapping relationship creates a straight intersection line of light, while a plurality of non-planar light orientated in a non-parallel, overlapping relationship creates a straight or curved intersection line of light. When projected against a target surface, a plurality of planar lights creates a projected cross shape, which may have an intersection point.

Abstract: The present invention provides a novel gas impingement and recoil mitigation system for firearms that includes separate systems that reduce recoil, muzzle rise, and user fatigue and includes a system that is of variable size to match the size and caliber of firearm to which the system will attach. The system can attach to a variety of firearms through an appropriately sized standard barrel connector. As propellant gas is redirected through a ported barrel, the force of the over-pressure wave caused by the propellant blast impinges on a piston-like weight-and-spring mechanism, which thrusts forward with a force that is opposite in direction from the typical backward force that causes muzzle rise and recoil. Numerous additional aspects are disclosed.
