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 sight for a firearm, comprising:
a lens and a housing supporting the lens;
wherein the housing has a forward end, a rearward end, a top side, a bottom side, a first lateral side, and a second lateral side;
wherein the first lateral side extends between the forward and rearward ends and includes at least one laterally-extending protrusion having a height measured along a direction from the bottom side of the housing to the top side of the housing, a width measured along a direction from the first lateral side of the housing to the second lateral side of the housing, and a length measured along a direction from the rearward end of the housing to the forward end of the housing;
wherein the first lateral side has a lead-in portion having a length measured along a distance from the forward end of the housing to the rearward end of the housing, the length of the lead-in portion being at least five times the width of the laterally-extending protrusion and extending forward from the laterally-extending protrusion;
wherein the lead-in portion is positioned laterally-inward of an outermost surface of the laterally-extending protrusion; and
wherein the lead-in portion has a surface roughness of less than 50 μm.
2 . The sight of claim 1 , wherein the height of the laterally-extending protrusion is greater than the width and the length of the laterally-extending protrusion.
3 . The sight of claim 2 , wherein the length of the laterally-extending protrusion is greater than the width of the laterally-extending protrusion.
4 . The sight of claim 1 , wherein the laterally-extending protrusion has a forward-facing surface and a rearward-facing surface; and
wherein the forward-facing surface is concave towards the forward end of the housing.
5 . The sight of claim 1 , wherein the length of said lead-in portion is at least six times the width of said laterally-extending protrusion.
6 . A sight for a firearm, comprising:
a lens and a housing supporting the lens;
wherein the housing has a forward end, a rearward end, a top side, a bottom side, a first lateral side, and a second lateral side;
wherein the first lateral side extends between the forward and rearward ends and includes a first laterally-extending protrusion having a height measured along a direction from the bottom side of the housing to the top side of the housing, a width measured along a direction from the first lateral side of the housing to the second lateral side of the housing, and a length measured along a direction from the rearward end of the housing to the forward end of the housing;
wherein the height of the first laterally-extending protrusion is greater than the width and the length;
wherein the first lateral side has a lead-in portion having a length measured along a distance from the forward end of the housing to the rearward end of the housing, the length of the lead-in portion being at least five times the width of the laterally-extending protrusion and extending forward from the laterally-extending protrusion; and
wherein the first laterally-extending protrusion has a maximum width of at least 1 mm positioned at least 5 mm rearward of the forward end.
7 . The sight of claim 6 , wherein the length of the first laterally-extending protrusion is greater than the width.
8 . The sight of claim 6 , wherein the first laterally-extending protrusion has a forward-facing surface and a rearward-facing surface; and
wherein the forward-facing surface is concave towards the forward end of the housing.
9 . The sight of claim 6 , wherein the lead-in portion does not extend laterally outward beyond an outermost surface of the laterally-extending protrusion.
10 . The sight of claim 6 , wherein the length of said lead-in portion is at least six times the width of said first laterally-extending protrusion.
11 . A firearm sight, comprising:
a housing having a rearward end, a forward end, and bottom side, and a top side; and
an optical sighting element comprising a lens supported by the housing;
wherein the housing has a portion that extends at least partially around a perimeter of the lens; and
wherein said portion has a rearward-facing side and a forward-facing side, the rearward-facing having serrations.
12 . The sight of claim 11 , wherein the serrations are positioned around at least half of the perimeter of the lens.
13 . The sight of claim 12 , wherein the rearward-facing side is positioned rearwardly of the lens.
14 . The sight of claim 11 , wherein the rearward-facing side is oblique to the bottom side of the housing.
15 . The sight of claim 11 , wherein serrations positioned above the lens are positioned forward of serrations positioned laterally outward of the lens.
16 . The sight of claim 11 , wherein the serrations comprise elongate peaks having lengths, widths, and heights.
17 . The sight of claim 16 , 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.
18 . The sight of claim 16 , wherein elongate peaks are separated by valleys; and
wherein the valleys have widths equal to the widths of adjacent peaks.
19 . The sight of claim 11 , wherein the peaks are truncated.
20 . The sight of claim 11 , wherein the forward-facing side of the portion is free of serrations.
