Picture of Angocoellum Mirrored Sighting Device
Very soon after finishing my previous project I realized a need for this device.

What was happening was the front (and only) sight on the rifle was a bit lower than where my head is when firing the rifle so when I looked at it there was a subtle angle between where I was looking and where the actual barrel was pointing. At extreme short range this was not much of a problem but if I moved about 15-20 feet back (still quite short given the range of the rifle) I would have to aim the rifle about 8 inches lower than where I wanted my projectile to hit. (In my video on the other project I shoot at a section of palm tree with spraypaint. I hit the center with no issues but I had to point the sight at the bottom of the outside circle to hit the center)

Obviously I needed to do something about this since moving forward or backwards would affect the aim and while this is fine for archery, a rifle ought to be more consistent.

What I decided to do was to bounce my line of sight off of two mirrors so that in the end, I had, in effect, a horizontal line from the sight to my eye instead of the angled one.

This is all good and well but there's still the issue of looks . . .I couldn't simply slap a couple of mirrors on and call it quits so after getting the basics designed I made sure to do a couple of things to keep with the steampunk theme.

If you like this please rate and comment! If not, please let me know what you think I ought to do differently so that I can improve in future endeavors!''

Come with me now and I will show you how I made this and how you can use it to develop your own!

The Springfield 1903 sniper scope was basically a telescope.

i love it. very functional. however i spy a problem. unless you mark one of the mirrors, probably the bottom one for looks, you will be able to twist the point of aim all over those mirrors. say if you pointed your gun just a little to the left or right, your sight will still show up, but it won't be centered, and will shoot off. same is for up and down. what i would do is take the bottom mirror and paint a black ~v~ (like an rear iron sight) shape at the height of the front sight. this way, you can line up the horizontal and vertical axises. (if you plan to do this, when finding the height to paint, take into acount the angle of the mirror. see picture.)

a more adventerous (and somewhat unrelated) idea is to mount the bottom mirror on an adjustable frame, so that you could turn a screw and lift the mirror higher. this would give you elevation control, and allow you to aim further.

Excellent idea! so far i've been making sure the barrel is aligned with the sight but that's iffy at best. Definitely will make that mod!
id totally use this... if i wasn't making a minigun accuracy's not that important when youre spraying a wave of metal..
does this really work?

yes this is fully functional
Once again, an awesome build! I never would've thought to make a periscope for a rifle. Kudos on a novel and artistic solution.

i wouldn't use it .. i cherish my lego to much (it my only outlet of crativity ...and anger)

Ingenious use of lego... And i have so much of that kind of lego technic. I'm going to have to get spray-painting my lego :P

heh glad to be an inspiration

OMFG you Used lego in it Who da thunk it
Kaelessin (author)  Articas6 years ago
lol yup! those gears fit together really well so I figured I'd repurpose them

Very nice we need some more steampunk things on instructables.

Your skill amazes me.
Kaelessin (author)  Mattrox6 years ago
well my hobby is ceramics which requires a lot of working with my hands so they get lotsa practice. XD thanks!
It needs a fake axel or something.

thanks for the comment . . .where do you think would be good?
The gears don't seem to actually be connected to the mirror in any meaningful way. I think the gears should extend onto the axel the mirror pivots on.
Kaelessin (author)  Fenris The bbw6 years ago
good point! I'll see what I've got lying around

uh yeah...excellent use of lego here. Paint is convincing
Kaelessin (author)  shooby6 years ago
thanks! the black base coat and a light touch of rub n buff makes the paint easy!
