This will teach you how to make a simple airsoft-scope from just garage tools & tape!
Step 1: Grab a Peice
Grab a piece from your tools that goes to a wrench like the one shown in the picture,
Get one big enough to fit your whole eye into.
Step 2: Putting on Cross-Hairs
Either get Black tape or Black Paper,
Then cut it into strips & tape it over the end like in the picture...
Step 3: Getting It on Your Gun...
If you don't like the color of your scope, paint it!
Now, to get it on your gun, you can either hot glue it on like shown in the picture, or tape it on...
Step 4: Look Through Your Scope!
Now that you have it, look through it!
