Abstract: A torsional fastening assembly provides a pin that leverages torque from a torsion spring and a pair of deviated free ends to fix a slotted nut in a locked threaded position. The pin includes a torsion spring that diverges into a pair of legs having free ends. A first free end includes a hump, while a second free end includes a generally 90° bend. The torsion spring exerts a torsional force on the pin that biases the pair of legs to diverge. The legs pass through a slotted nut and a threaded bolt. The hump and the generally 90° bend are engaged around the respective threads of the slotted nut and the bolt, such that the slotted nut is restricted from rotating relative to the bolt. The pin is fabricated from stainless steel to enhance tensile strength and inhibit rust. A cap conceals the pin and the slotted nut.

Abstract: A universal tactical mount (10) is adapted to attach to a firearm barrel (18) and to have a plurality of firearm accessories (41, 42 and 43) mounted to it. The universal tactical comprises a plate (11) divided into an upper portion (12) and a lower portion (13) and an opening (16) on the boundary between the portions sized to tightly circumscribe the firearm barrel, thus fixedly mounting the universal tactical mount to the firearm. The plate further includes at least one mounting station (30, 31 and 32) adapted to fixedly hold a firearm accessory, such as a light source (e.g., laser, visible light or infra-red).
