Weapon sight
An adjustable firearm sight includes a body made of a flexible and resilient material. The body includes an elevation arm connected to the body and extending proximally therefrom to a sight portion, where the elevation arm and the body comprise a monolithic structure. A cam body below the elevation arm has a cam surface in contact with a bottom surface of the elevation arm, where the cam body is rotatable to change a vertical position of the sight portion. Also disclosed is a front sight assembly where a sight element is disposed in a longitudinal bore through a sight body. A proximal end of the longitudinal bore has a reduced size. At a distal end, a retention pin is disposed in a retention bore that extends transversely to and intersects the longitudinal bore such that the retention pin occupies the longitudinal bore to retain the sight element.
1. An adjustable sight for a firearm, the sight comprising:
a body made of a flexible and resilient polymeric material, the body defining longitudinal gaps to define an elevation arm connected at its distal end to the body and extending proximally to a proximal end portion, wherein the elevation arm and the body comprise a monolithic structure and wherein the elevation arm is disconnected from the body along the longitudinal gaps; and
a cam body below the elevation arm, wherein the cam body is adjustable to change a vertical position of the proximal end portion of the elevation arm.
2. The adjustable sight of claim 1 , wherein the cam body is rotatably adjustable.
3. The adjustable sight of claim 2 , wherein the cam body has a generally cylindrical geometry and extends crosswise to the elevation arm.
4. The adjustable sight of claim 3 , wherein at least one end portion of the cam body is received in a recess defined in the sight body.
5. The adjustable sight of claim 3 , wherein the cam body defines one or more flats on an outer surface thereof, each of the one or more flats corresponding to rotation of the cam in an amount from 5 to 30 degrees.
6. The adjustable sight of claim 5 , wherein at least one end of the cam body defines a tool recess and wherein the body defines an opening to the tool recess.
7. The adjustable sight of claim 6 , wherein the tool recess is selected from a slot, a plus, a hexagon, a square, a triangle, and a star.
8. The adjustable sight of claim 1 , wherein the elevation arm defines a slot extending axially along a top surface thereof.
9. The adjustable sight of claim 1 , further comprising an aiming portion configured to be removably attached to the proximal end portion of the elevation arm.
10. The adjustable sight of claim 9 , wherein the aiming portion comprises a left aiming indicator and a right aiming indicator.
11. The adjustable sight of claim 10 , wherein the aiming portion defines a channel extending axially through a top of the aiming portion and positioned between the left aiming indicator and the right aiming indicator.
12. The adjustable sight of claim 1 , wherein the elevation arm and the body define a living hinge.
13. A handgun slide comprising the adjustable sight of claim 1 .
14. A handgun comprising the handgun slide of claim 13 .
