This invention relates to the field of golf putter design. After the golfer has assumed his putting stance, the Eyelignment putter incorporates features that provide a golfer specific visual feedback related to whether the golfer's eyes are correctly aligned with the golf ball, the putter-head, and the intended target-line. This visual feedback is not available in current putter designs. Current putter designs may have design features that help a golfer aim and align a putter's face to the golf ball and along the intended target-line, but current designs provide no visual feedback related to whether the golf ball and putter-head are actually properly aligned, and no feedback related to the alignment of a golfer's eyes. The Eyelignment design provides golfers visual feedback to help golfers consistently achieve the proper alignment of their eyes to the putter-head and the target-line and does so while the golfer is taking his putting stance.

A sighting system for a firearm and related methods are disclosed. The sighting system has front and rear flip-up sights, wherein the front sight comprises a flip-up portion having an aperture through which a sight post can partially extend; a knob comprising one or more notches on a first side and the sight post extending from a second side; at least one detent arranged to face and interact with the one or more notches. The knob is configured to rotate about a first axis, where the rotation causes the sight post to move in a first direction along the first axis; tilting of the knob in a second direction based on the detent interfacing with the notches; and tilting of the sight post in the second direction, thereby forcing at least a portion of the sight post to press against the aperture, or a combination thereof.

Described herein are a shotgun optic plate cover, and methods for making and installing same as well as retrofitting existing shotguns to accommodate the shotgun optic plate cover, with an integrated rear sight to enable either optics enhanced, or non-optics enhanced aiming capabilities for shotguns.

A firearm sight has a body having an attachment facility configured to connect to a pistol having a forward target end and a rear end. The body has a forward end and an opposed rear end associated with the forward and rear ends of the firearm. The body defines a bore with a forward opening and a rear opening. An elongated insert is received in the bore and has a rear end and a forward end. The insert and body have an insertion limiting facility configured to admit insertion of the insert with the rear end of the insert inserted via the forward opening of the bore, and to prevent passage of the insert beyond a limited insertion amount. The insertion limiting facility may include the bore defining a step, a greater bore width forward of the step and lesser bore width rear of the step.

A rear sight and related assembly are disclosed. The rear sight has a notch component coupled to a base portion. The notch component includes a notch forming a channel through the notch component, the channel having a channel direction. The base portion has a first flange having a first aperture and a second flange having a second aperture couple coupling with an optic mount. The assembly of the rear sight includes the rear sight coupled to the optic mount. The apertures of the rear sight are configured to concentrically align with mounting holes of the optic mount. The optic mount is configured to couple to a slide of a firearm.

In some embodiments, an apparatus comprises a first body and a second body aligned upon an axis. The first body comprises a first sight window and a first side edge, a second side edge and a base edge defining the first sight window, and a first central indicator. The second body comprises a second sight window and a first side edge, a second side edge and a base edge defining the second sight window, and a second central indicator. The axis extends through a center of the first sight window and through a center of the second sight window.
