Introduction: Pineapplebob's Sniper Rifle

Picture of Pineapplebob's Sniper Rifle

This is a sniper rifle made out of knex. It is over 3 feet long and shoots farther than 120 feet. Please comment. PLEASE RATE. Be sure to check the yellow squares on the pics, for they have important information. I got this gun to shoot through a few cola cans and mulitple pieces of cardboard without sharpened rods. I got it to shoot through 16 pieces of cardboard and still, it kept going. This gun's effective range is 110 feet, however it can shoot up to 200 feet. Also, i got it to shoot through 5 cola cans. Once again, i didn't use a single sharpened rod. I did use a sharpened rod when it came to the 16 p;ieces of cardboard, though.Another good side to this gun is that the magazine is really easy to load, so there is no struggling when you're using it to play against your friends (however, i do suggest lowering the power a bit so you do not injure your friend greatly.)

Step 1: The Barrel

Picture of The Barrel

This is the barrel of the gun. It is almost exactly like Gorkem's barrel but it has a different end to it.

Step 2: The Cover

Picture of The Cover

This is a cover to the barrel. It shouldn't be that hard to understand. Don't build the hidden magazine yet.

1: The Completed Cover
2+3: Make Two Of These
4: Make These
5: Attach Them Here
6: Slide The Third One Through Here
7: Attach The Second Frame. Add the connectors
8: Make two of these
9: Attach one here
10: Attach one here too

Step 3: Brace

This keeps the wheel on the barrel sturdy.

Step 4: The Magazine

Picture of The Magazine

This is a hidden magazine. I made it hidden because i didn't like how the magazines on other sniper rifles jutted out of the barrel.

1+2: Loading
3: Make These
4: Add The First One Here
5: Add The Second One
6: Attach A Red Connector Between The Two Magazine Sides

Step 5: The Center

This is the center of the gun.
1: Build This
2: Add It Here
3: Make 5 Of These
4: Connect Them Like So
5: Make This
6: Attach It Here
7: Make This

Step 6: The Handle

3: Make These
4: Connect Them Here
5: Make Two Of These
6: Make Three Of These
7: Attach It Like So
8: Finished Product
9: Attach Handle Where Shown

Step 7: The Trigger and String Attachments.

Picture of The Trigger and String Attachments.

The trigger is the same as the one on Gorkem's sniper rifle. The string attachment is the same, too.

Step 8: The Stock and Butt

Picture of The Stock and Butt

The stock is quite short. The butt is very comfortable and fits right under your arm. It is strong, so you can lean against it.

Step 9: Loading and Firing

1: The Firing Pen is a gray rod with an orange connector on it. Add two rubberbands and stretch them from the orange connector to the end of the barrel.
2: Tape the orange connector so it will stay sturdy.
3: Slip a string through the hole in the orange connector and double knot it.
4: Add four blue rods in the magazine as shown in step 4.
5: Attach a rubberband onto the block trigger.
6: Grab the string and pull it back. The string pulls the firing pen back. When the firing pen is back far enough, the block trigger will fall down into place, blocking the firing pen from moving back further into the barrel. At the same time, the blue rod from the magazine should fall down onto the tan connectors.
7: Pull the real trigger, pulling back the block trigger and launching a blue rod at anything infront of you. (I am not responsible for who or what you launch this at. Any injuries will be you own fault. Do not shoot at animals.)
8:Repeat until magazine is empty, then refill.

Skreetsha (author)salbabob2008-08-25

lol why??? we build, we shoot, we have fun, thats it! whats wrong wth that?

salbabob (author)Skreetsha2008-08-25

i admit now that knex guns are frankly AWESOME(this one included) but still you have to have a lot of time and patience for this kind of thing which most people dont have and look at I_am_Canadian's cannon thing ITS INSANE it must have taken forever to build and it used like 3,00 piecesces (its awesomely awesome though) my point is- how can serious knex builders have time for anything else?!

bighead5454 (author)salbabob2009-06-26

if this uses 400 sumthin pieces i think IAC's cannon would use a lot more

Hiyadudez (author)bighead54542010-02-09

It used about 2,900 pieces.

finmonster (author)salbabob2010-01-04

i can build most of the things i do in 2-3 hours

Skreetsha (author)salbabob2008-08-26

well i normally build 2 hours when its a normal week and then my dad makes me do something else but now that i have vacation im building and shooting all day long

salbabob (author)Skreetsha2008-08-26

I guess its pretty fun, but i mean don't you get tired of it? plus how much money have you spent on knex so far

Skreetsha (author)salbabob2008-08-26

i guess like 245 euros (im dutch)

salbabob (author)Skreetsha2008-08-26

hmm thats a pretty small amount ebay? how many pieces do you have?

lol. 17000, no joke.

I have 14000 pieces, not very much!!

builder968 (author)salbabob2009-01-28

i have ~6,000 now.

Skreetsha (author)salbabob2008-08-26

i never bought on ebay i have only bought boxes in stores

salbabob (author)Skreetsha2008-08-27

i see how many pieces?

Skreetsha (author)salbabob2008-08-27

4 blue boxes is 1700 pieces 2 red ones dont know how much pieces but im guessing 500 so thats like 2200 pieces

lol. 17000 for me.

Lol, i now have:
6 blue boxes = 6 x 428 = 2568
4 red boxes = 4 x 324 i believe, = 1728
All 6 OCC choppers = 125 + 134 + 90 + 145 + 153 + 120 = 767
1 Starburst Spinner Set = 457 i believe, = 457, DUH!
That counts up:

5520 piecs :D

salbabob (author)Skreetsha2008-08-27

sweetness do you mostly build other people's guns or make your own designs?

Skreetsha (author)salbabob2008-08-28

i create my own designs with sometimes someone elses trigger system

salbabob (author)Skreetsha2008-08-28

preety cool guns:) :D

Skreetsha (author)salbabob2008-08-28

thank you :)

builder968 (author)Skreetsha2009-01-28


I still have time left in the day to do homework ( a lot), 45 min of piano (each day), 2 hours of guitar (each day), and skateboard (tue. - fri.).

permission to use handle good sir for my soon to be sniper

go ahead. Looks like it has a good frame.

you can see it at my account under instructables

i don't really spend tooo much time on my knex. Maybe 30 min to 1 hour twice a week. Pieces just come from eBay.

So I guess its just a buildup of a little time each day?

I_am_Canadian (author)salbabob2008-08-25

Oh its pretty easy.

salbabob (author)I_am_Canadian2008-08-26

mikstr2 (author)salbabob2009-11-06

i spend like, 5 hours a day on knex guns and i have over 5000 peices

knexsniper1 (author)2009-03-07

Hi, I built this gun, and not to sound rude or anything, but it was not worth it, it was to hard to load, i broke a whole bunch of pieces, and it would not fire more than 30 or 40 feets, regardless of how many #64 rubberbands i put on it. if you can think of another gun that has a huge range and accuracy, that would be cool. Thanks!

An Villain (author)knexsniper12009-07-31

i have a nice crossbow (knex) i can post pictures but i cannot post an instructable right now it is compact and can support my weight sitting on it.

randomocity (author)knexsniper12009-07-24

Lowney (author)2009-05-11
