A firearm sling includes a shooting rest. The shooting rest may include a bifurcated cavity filled with deformable media. The bifurcated cavity defines a trough along at least a portion of a length of the shooting rest. The firearm sling may be coupled to a firearm to facilitate carrying the firearm over a shoulder or across a torso, the shooting rest providing padding for comfort in carrying the firearm as well as a support for the firearm to improve marksmanship.

A pistol chassis is disclosed which may include a lower housing, an upper housing, a proximal enclosure, a distal sleeve, and a proximal accessory. The distal sleeve, lower housing, and upper housing may be secured together to form a tubular member for receiving a pistol. The lower housing further may include a distal segment, a proximal segment and an intermediate segment. The distal segment may include a pistol frame receptacle and a trigger guard enclosure. The proximal accessory may be a folding stock. The pistol chassis may house a pistol to produce a firearm apparatus.

A holster system that comprises a holster and an accessory configured to be fixed to a mounting rail of a handgun. The holster has a holster body with a pair of opposing wall portions defining a cavity. A retention mechanism of the system has a blocking portion movable between a blocking position and a non-blocking position. The blocking member at least inhibits removal of the handgun and accessory if the handgun and accessory are urged rearwardly before a thumb receiving portion is depressed. The blocking portion is on a spring member that is deflected by an elongate exteriorly extending sliding member that has a cam surface that selectively deflects the spring member from the blocking position.

A firearm carrier that is design and configured to hold a firearm. In one embodiment, the firearm is a pump-action (or slide-action) firearm, such as a scattergun. The firearm can have a rear portion with a pistol grip, and a forward portion with a barrel and a pump-action (or slide-action) receiver. The firearm carrier can be secured to a user's waist and leg, and then the firearm can be removably secured to the firearm carrier. Advantageously, the firearm carrier is configured to receive a portion of the barrel of the firearm and can thus be secured to the firearm carrier. The firearm can also be rapidly removed from the firearm carrier should the user desire to remove the firearm from the firearm carrier.

A sling that can be attached to any rifle, long gun or case, with a single main section of webbing running the entire length of the sling, routed through a linearly moveable quick release buckle, then looped through an oval ring fixed to one end of the sling, back through another oval ring attached to the quick release buckle and back towards the fixed oval ring to form a compound S-shaped adjustment loop with three layers of webbing, laying one on top of the other, giving the sling additional length when expanded, while also enabling it to be fully retracted. The quick release buckle can linearly move along the full length of the sling with the quick and easy manipulation of the buckle.

Sling sliders have a body defining an elongated sling strap passage configured to receive an elongated sling strap, the elongated sling strap passage defined at least in part by an elongated bar having opposed ends, the elongated bar defining an elongated cord passage extending between the opposed ends of the elongated bar, a cord received in the elongated cord passage, and the cord having a received portion within the elongated cord passage and a handle portion extending outside the elongated cord passage such that the handle portion operates to exert a motive force on the body. The sling slider may be a triglide. The body may have three parallel bars, and the elongated bar defining the elongated cord passage may be positioned between a second bar and a third bar. The body may define a pair of elongated sling strap passages on opposite sides of the elongated bar.

Representative implementations of devices and techniques provide a thigh mount assembly, to mount and to support an implement (such as a handgun, for example), an implement holster (such as a handgun holster or shell, for example), or the like, along with one or more accessories (duty pouches such as magazine carriers, a baton holder, a pepper spray canister, flashlight, or other carriers or accessories, for example) in a variety of configurations while worn on a person. Alternately, the thigh mount assembly may be used as a support for additional accessories (e.g., weapons, tools, instruments, supplies, etc.) as desired, such as accessories that are desired to be carried on the person. The assembly includes one or more removable or permanent attachment devices that may be used to temporarily or permanently attach the one or more accessories, as well as multiple attachment points that may also be used in like manner.

A support hook assembly is configured to support a rifle worn by a human. The support hook assembly has a clip having a front plate connected to a pair of clip legs. A hook attachment block is joined to the front plate and further has a first pin slot and a second pin slot. An upper hinge knuckle recess, a first lower knuckle recess and a second lower knuckle recess are joined to the front plate adjacent to the hook attachment bloc. A hook has an upper knuckle and a lower knuckle. A pin is inserted through the upper knuckle, the first pin slot, and the lower knuckle. The hook is adapted to support the rifle worn by the human.

A process for making nanoparticles of biocompatible materials is described, wherein an aqueous reaction mixture comprising cerous ion, ethylenediaminedisuccinic acid, an oxidant, water, and optionally citric acid, is provided along with temperature conditions to directly form within the reaction mixture, a stable dispersion of cerium oxide nanoparticles. Biocompatible nanoparticles comprised of cerium oxide, ethylenediaminedisuccinic acid, and optionally citric acid, are described. An increase in catalase-like enzyme activity is demonstrated by cerium oxide nanoparticles prepared with citric acid and ethylenediaminedisuccinic acid.

A gun cleaning apparatus includes a cleaning tool and a storage case. The cleaning tool has a cleaning section and a pull cord having a distal end for pulling the cleaning section through a gun barrel. The storage case is configured for enclosing the cleaning tool. The storage case includes a substantially hollow container defining a rim at opening thereof, and a removable lid positionable between a closed configuration and an open position. The removable lid includes a handle section for gripping by a user to assist with pulling the cleaning tool through the gun barrel in the open configuration and configured to engage the rim in the closed configuration, and a connection section extending from the handle section, the connection section defining an elongated slot and a cavity for securing the distal end of the pull cord therein.
