Introduction: Red Dot Sight
You might need to edit your sight based on the dimensions of your laser pointer.
Step 1: The Base
The hole in the front and sides are necessary to be able to use the sight, so make sure you include them. Also make sure that the pointer is sideways, otherwise the trigger won't work. The piece of paper is optional, I only needed it to make it show more laser so that it will be brighter. You might not need this depending on your pointer.
Step 2: The Trigger
You don't need that specific piece, so long as it can go two bricks deep.
Step 3: Turning It On
To activate the sight, push the trigger on the side in. To turn it off, pull it out. This was my first instructable, so tell me how I did!
