Abstract: An archery arrow is provided to include a shaft that is tubular and includes an exterior surface and an opposing interior surface, with an insert secured to the shaft. The insert can define a hole configured to join a component, for example, a broadhead with the arrow. The hole can be round and concentric with the exterior surface of the shaft, and in some cases non-concentric with the interior surface. The insert can be adhered to the shaft and later machined to define the hole to provide the concentricity of the hole and the shaft exterior or an associated outer diameter. When a component such as a broadhead is joined with the arrow via installation in the hole, the component can be centered relative to the shaft exterior. A related method of manufacturing an arrow is provided.

Abstract: An expandable broadhead is provided with a ferrule defining a slot within which one or more blades are moveably mounted to a pin. A retainer in the slot can secure the blades in a closed mode when an arrow associated with the broadhead is shot from an archery bow. The retainer can include a dimple and a blade can include a retainer hole within which the dimple nests to secure the blade. The retainer hole can be common with and/or extend from a mass reducing opening defined by the blade. The dimple can ride over contours of the blade on a path to enter the hole with significantly less force than that to release the dimple and retainer from, and deploy, the blade. The slot can increase in depth beyond the dimple to reduce frictional engagement of the blades with slot sidewalls during deployment. A related method is provided.

Abstract: An archery bow is provided including opposing limbs and a riser. The riser can include a riser handle and one or more primary riser elongated elements extending away from the handle to respective limbs. The primary riser elongated elements can be straight, elongated round or other shaped tubes, rods or bars constructed optionally from a composite or other material. Vents can be included in ports of the riser to facilitate escape of air when riser elongated elements are installed in those ports. The riser can include one or more connector lugs disposed between tube portions to facilitate attachment of accessories to the elongated elements. The elongated elements can be bonded, adhered or otherwise fixed to the riser handle, struts, lugs and/or limb pockets, which can be constructed from a metal such as aluminum, titanium or an alloy, and which can handle significant moments and forces transferred via the elongated elements.

Abstract: An aiming device is provided including an illumination device and an optical element wherein the illumination device projects a primary dot and at least one secondary alignment dot distal from the primary dot to aid a user in obtaining a view of the primary dot when the aiming device is in an aligned mode, the primary dot is visible within a field of view of the user, but the secondary alignment dot is not visible. When the aiming device is in a misaligned mode, the secondary alignment dot is visible to the user, but the primary dot is not. The secondary alignment dot provides instruction to the user to realign the aiming device relative to the field of view of the user so that the aiming device transitions to the aligned mode. A related method of operation is provided.

Abstract: An archery bow assembly is provided including an open sided spacer which is mountable to an axle on an archery bow and removable therefrom without removing the axle entirely or partially from a limb of the archery bow. The spacer can mount on the axle adjacent a cam rotatable on the axle, and can include an outer perimeter and an axle aperture. A recess can extend inward from the outer perimeter to the axle aperture so that the axle aperture and recess form a continuous opening. The spacer can be of a C-shape or E-shape. A cup spacer having an outer rim can capture the open sided spacer to secure it to the axle, yet still allow removal from the axle without removing the axle from the limb arms adjacent the cam. Related methods also are provided.

Abstract: An aiming device is provided including an illumination device and an optical element wherein the illumination device projects a primary dot and at least one secondary alignment dot distal from the primary dot to aid a user in obtaining a view of the primary dot when the aiming device is in an aligned mode, the primary dot is visible within a field of view of the user, but the secondary alignment dot is not visible. When the aiming device is in a misaligned mode, the secondary alignment dot is visible to the user, but the primary dot is not. The secondary alignment dot provides instruction to the user to realign the aiming device relative to the field of view of the user so that the aiming device transitions to the aligned mode. A related method of operation is provided.

Abstract: An archery bow is provided including a cam rotatable about an axis, a bowstring disposed in a bowstring track of the cam having a plane of rotation perpendicular to the axis, and a power cable that is displaced along the axis toward the plane of rotation to concentrate a force of the power cable near a force of the bowstring along the axis to inhibit twisting of a limb, when the bow is drawn. A related method of use is provided.

A recess can extend inward from the outer perimeter to the axle aperture so that the axle aperture and recess form a continuous opening. The spacer can be of a C-shape or E-shape so that it can be frictionally pressed onto the axle and removed therefrom without removing the axle from the limb arms adjacent the cam. Related methods also are provided.

Abstract: An archery training aid is provided including a body and a finger rest extending outward at an angle from a base. The finger rest can include a finger rest surface configured to engage one or more fingers of a hand. The base can be configured to be placed in engagement with a first lateral grip surface of a bow grip so that the finger rest surface is disposed at a first angle between 25° to 65°, inclusive, or between 30° and 50°, inclusive, relative to the first lateral grip surface. A related method of use is provided to impair or prevent bow torque imparted by an archer's hand on a bow.

Abstract: A grip for a weapon is provided and can include a user engagement area including a first surface on the weapon, a first layer including an aerogel, the first layer disposed adjacent the first surface, and a first engagement member disposed over the first layer in the user engagement area. The first engagement member includes an exterior surface that engages an appendage of a user when the user holds the weapon. The first layer including the aerogel insulates the first engagement member so that thermal energy transfer between the user and the weapon is impaired. The weapon can be an archery bow, a firearm or any other weapon including a grip or portion that is engaged by an appendage of a user.

Abstract: An aiming device is provided including a body, an optical element joined with the body that has selectively displayed thereon a dot visible to a user along a first line of viewing, and a power indicator distal from the optical element, where the power indicator emits illumination along a second line of viewing, offset from the first line of viewing. The power indicator can alert the user via the illumination that the dot is or is not displayed on the optical element, without the user needing to directly view the dot along the first line of viewing. The illumination emitted by the power indicator can be of a first visible wavelength range, e.g., blue, and the dot can illuminate in a second visible wavelength range different from the first visible wavelength range, e.g., green or red, so the likelihood of confusing the power indicator with the dot can be reduced.

Abstract: An aiming device is provided including a body, an illumination device associated with the body and an optical element, where the illumination device is operable to selectively display a dot on the optical element being visible to a user. The optical element can include an upper edge and a lower edge, and the dot can display closer to the upper edge than to the lower edge, in some cases in the upper half or one third of the height of the optical element. The device can include a protective frame to which the optical element is joined, and the optical element upper edge can be unconcealed by any part of the protective frame above the upper edge, falling within an open top span of the frame. The optical element can be removable and replaceable relative to the protective frame, with a retainer plate temporarily securing the element to the frame.
