Airsoft Gun Sight

This thing is inspired by the "see all open sight" by "Oversight Shooting Technologies". Although, the concept has been adapted for use with airsoft guns. The sight is adjustable (using M3 screws) for both elevation and azimuth. When mounted to a KWA kriss, 100 shots were fired and the zero has not been lost. I have not played an airsoft game with the sight though, and given the current design, it is unlikely to survive one without design improvements. I am currently designing the second revision to address the BB-resistance issue. and to lower the overall profile of the sight.

When using the sight, the target should be aligned with the top of the triangle's uppermost apex. After that, the rest is up to the user.

There are three printed parts and an assortment of hardware in addtion to a single lens. The parts are as follows:

1x RP Reticle Carrier

1x RP Sight body

1x RP Rail Adapter

(The above RP parts benefit from printing in PLA. Stiffness is beneficial when dealing with optics and other systems where alignment is a requisite for accuracy)

2x M5 Nut

2x M5 screw

1x 19mm diameter convex lens (Not sure which focal length I used) Perhaps Edmund's Industrial Optics can provide one Stock# 74-310 may be useful, but I've yet to try it.

1x 34mm M3 screw (to tighten rail adapter to gun rail)

1x 25mm M3 screw (for azimuth adjustment)

1x 12mm M3 screw (for elevation adjustment)

1x 20mm M3 screw (as a reticle carrier pivot)

2x M3 nuts

1x M3 Nylock nut (to secure azimuth adjustment screw)

RC silicone fuel tubing for use as a spring to apply pressure to the various components

Lexan / acrylic to supply light to the reticle (I did not have the edge-glow style acrylic used by the "see all" people. So I milled out two squares of lexan and glued them together to get the height I needed. I then mirror polished the side that the reticle is applied to.

The reticle shown here is made by applying a bright highlighter to a piece of paper then using an inkjet printer to apply the reticle pattern on top of the highlighted section. The reticle pattern in then cut out using a #11 X-Acto blade. The resulting paper reticle pattern is attached to the lexan light block using a glue stick. (Elmer's "disappearing purple" school glue).
