Cheap Red-Dot Scope




This is a cheap red-dot scope I made using house-hold materials. The only thing you might need to buy is electrical tape.

Step 1: Materials

These are there materials you will need:
1 toilet paper roll
1 Roll of electrical tape (scoth tape can be used, ut will look much better with solid black tape)
1 Pair of Scissors
1 Sharpie, color of your choice (Red for Red-Dot, I used Green in this one)
1 Saran wrap roll
1 Gun to mount it on (I used my Airsoft UTG MK23)

These are house-hold materials, except maybe the electric tape.

Step 2: Putting on the Saran Wrap

Cut a peice of Saran Wrap approx. 5 inches by one foot and straighten it out. Take the Saran Wrap and cover one end of the tube tightly. Grab the tape (this part is tricky, it took me 3 tries) and secure the tape so it is tight, and not loose on any areas. I then like to cover the entire roll with the tape, just so it looks cool.

Step 3: Drawing the Dot

Take the Sharpie you chose and draw a dot or other crosshair on the Saran Wrap that you put on. I chose a plus and dots. You could also cover the side of the roll with wrap and make a dot on one and a circle on the other, that's up to you. You can also use a ruler to find the exact center, but it doesn't work good.

Step 4: Attachment

To attach the scope, I simply taped the scope to the gun. If you gun is real, a spring airsoft gun, or a gas/electric blowback, make sure the tape stops "on the slide" or you will tape the slide to the gun, which isn't good. Make sure the scope is relatively lined up with the iron sights,and enjoy!

    that is actulally not gonna be an acurate redot sight because the scope lenses that a red dot sight have lase emitters that converge in the order for this to work you would need a laser apparutus that can be zeroed in for the right distance.for example that wouldnt work for a high powered rifle because it was show wher the scop is pointed it wouldn tdeal with the arc of the bullet thats how long range shots take place .you got one thin right about this

    dude hes making like a 10 cent scope and your criticizing it. I dont think any one here that is actually making it is gonna care if there spring m16 cant hit a target on the left nipple from 60 feet away.

    stop being so cynical, its a pistol so its for short range and its supposed to be cheap cos not all of us can afford $50 lazer sights.

     You'd be better off using the Iron Sights already on your pistol. In order for this thing to be even remotely accurate you could at least put another piece of seran wrap on the rear of the scope and draw another + sign lined up with where the gun hits at a certain range, this "scope" won't be accurate unless you're exactly behind it.

    yeah but he is just trying ot explain that this isnt even gonna be close to as acurate as a red dot sight because it ISNT a red dot sight its an aperture sight

    dude this is made to be a cheap solution for those w/out a scope give him a break id like to see you make a perfectly accurate scope for like $2. really.

    230 FPS with .20 gram BBs 290 with .12 gram BBs. It's a great gun,only 20 bucks comes with two mags and a silencer, but i recommend using .20 because .12s curve up way too much.


    Reply 9 years ago on Introduction

    Doesn't go that much further up than that. If 290 is horrible, you can't call 320-350 fantastic, can you?

    No but you can call 450 fantastic, no offense but ya 290 sucks. Like i would not be able to use it for anything but a boomerang because i doubt you can feel the bullets when you get hit. my first gun was a crappy mini uzi that you can not feel 3 feet away shooting you right in the chest
