Introduction: Lego Red Dot Sight [Functional]

Picture of Lego Red Dot Sight [Functional]

Plastic sights on your Lego gun can be pretty lame huh? But with this simple, realistic, and easy-to-build red dot sight, you can add some more realism to your gun!

So I wanted to make a sight but I didn't want to do it the convention way of using a windbreaker screen for the glass part and then drawing a dot with a red shapie or something. So I thought of using a clear disc inside a tire with a red part for the dot instead. And this is the outcome! Hope you enjoy building and tell me what you think!

Stick to the image notes and you should be ok.

Looks great, do you know if you can attach it to a Knex gun?

This is very good quality. Probably is better then any of the other lego red dot sights on the site.

Thanks! I was thinking about making other types of optic sights!
