Firearm sights and assemblies
Sights of the present disclosure comprise a housing supporting an optical sighting element, such as one or more lenses or iron sights. A first lateral side of the housing has a laterally-extending protrusion and a lead-in portion forward of the laterally-extending portion. In some arrangements the lead-in portion is laterally-inward of an outermost surface of the laterally-extending protrusion and has a surface roughness of less than 50 μm. In some instances, the laterally-extending protrusion has a width of at least 1 mm and the lead-in portion has a length of at least five times the width of the laterally-extending protrusion.
1. A firearm sight, comprising:
a housing having a rearward end, a forward end, a left lateral side, a right lateral side, a bottom side, and a top side;
the housing defining a lens opening that forms a window to look through the housing along a rearward end to forward end direction;
wherein the housing has a portion that extends at least partially around a perimeter of the lens opening and to a first height above the bottom side;
wherein the top side of the housing at the rearward end is a second height above the bottom side, the second height being less than the first height;
wherein said portion has a rearward-facing side and a forward-facing side, the rearward-facing side having serrations and being separate from and spaced forward of said rearward end;
wherein the serrations are defined by v-shaped grooves extending along a direction from a left lateral side of the housing to a right lateral side of the housing; and
wherein the forward-facing side is free of serrations.
2. The sight of claim 1 , wherein the serrations are positioned around at least half of the perimeter of the lens opening.
3. The sight of claim 2 , wherein the rearward-facing side is positioned rearwardly of the lens opening.
4. The sight of claim 1 , wherein the rearward-facing side is oblique to the bottom side of the housing.
5. The sight of claim 1 , wherein serrations positioned above the lens opening are positioned forward of serrations positioned laterally outward of the lens opening.
6. The sight of claim 1 , wherein the serrations comprise elongate peaks having lengths, widths, and heights.
7. The sight of claim 6 , wherein the lengths of the elongate peaks extend along a direction extending from a first lateral outer surface of the housing to a second lateral outer surface of the housing.
8. The sight of claim 6 , wherein elongate peaks are separated by valleys; and wherein the valleys have widths equal to the widths of adjacent peaks.
9. The sight of claim 1 , wherein the peaks are truncated.
10. The sight of claim 1 , wherein the rearward-facing side is sloped such that a top portion of the rearward-facing side is closer to the forward end and a bottom portion of the rearward-facing side is closer to the rearward end.
11. The sight of claim 1 , wherein the top side at the rearward end defines a groove extending along a length of the housing.
12. The sight of claim 1 , wherein said forward-facing side has an upper portion, a lower portion nearer said bottom side than said upper portion, and an intermediate portion positioned between said upper portion and said lower portion; and
wherein said upper and lower portions of said forward-facing side are positioned further forward than the intermediate portion.
13. An optic for a firearm, comprising:
a portion defining a closed-perimeter viewing window visible from a rear of the optic;
the portion extending around the closed-perimeter viewing window to a first height above a bottom of the optic;
wherein a top of the optic at the rear is a second height above the bottom, the second height being less than the first height;
wherein said portion extending around the closed-perimeter viewing window has a rearward-facing side and a forward-facing side, the rearward-facing side having serrations and the forward-facing side being free of serrations;
wherein a rearward-facing surface at the rear of the optic has serrations;
wherein the serrations are defined by v-shaped grooves extending along a direction from a left lateral side of the housing to a right lateral side of the housing.
14. The optic of claim 13 , wherein the top side at the rearward end defines an elongate groove extending along a length of the housing.
15. The optic of claim 13 , wherein serrations at a bottom of the rearward-facing side are positioned rearward of serrations positioned at a top of the rearward-facing side.
16. The optic of claim 13 , wherein an uppermost portion of the forward-facing side is positioned further forward than a portion of the forward-facing side below the uppermost portion.
17. The optic of claim 16 , wherein a lowermost portion of the forward-facing surface is positioned further forward than the portion of the forward-facing surface below the uppermost portion.
