Introduction: Storm 221 V2.4 Battle Sniper

Picture of Storm 221 V2.4 Battle Sniper
Here it is. My yellow rod mag fed Battle sniper. It was built with large scale multiple floor knex wars in mind, and just nicely, fits that purpose very nicely.

The Storm 221 incorporates a new size magazine which is just outside the width of a yellow rod, minimising Magazine friction from the old design. The mag is sadly not removeable, but makes up for this in the fact that there is hardly any trouble whatsoever in transition from mag to mag well.

This shoots about 95 ft with 3 rubberbands, one on its own and the others tied together. I couldn't try with more on, because I'm using them on my *gasp* secret project! No sneak previews yet, but you'll see when it gets posted.

Its accuracy is very good too. From a range of 30 ft, I can hit a cardboard target that is about 50cm2 almost all the time.

Version History:
  • V1.0 I rebuilt the 221 again with hopes of making a V2.
  • V2.0 Ok, I Added a magazine, like the one in the 220 V2. It fired significantly shorter distance. I didn't like this. (Jamalam cat is NOT amused)
  • V2.1 I modded the mag well to have less friction and more power. It worked out better, but for a sniper, I decided that 40 ft was not enough.
  • V2.2 I decided at this point to build it a new body, which worked out great, but for some reason after this the range was lowered by over 12 ft. I still have no idea why. Between this version and the V2.3, I managed to fire it and blow up the mag, destroying an orange connector :(. Yerjoking, this was the version I showed you on MSN, and the pics are in the intro for everyone else.
  • V2.3 I wanted the range back to proper standards. I started on a new mag design using green rod horizontal intervals instead of white rod horizontal intervals. For this to work, I also modded the mag well. This, I found, shot 95 ft. I am happy!
  • V2.4 I just made some minor touch ups to the looks, added a bipod, and posted here!

Range of 90 ft.
Accuracy to within 25 cm off target from 30 ft.
Has yet to jam, the bullet always leaves the barrel.

When you move fast, you can't aim at all.
Hurts when it hits you.

This is good in war situations, because you can snipe from many angles. It is slightly lighter than the 220 V2 - which was built more to scare people witless in a war situation because of its hugely unnecessary bulk - which allows this to be fast aimable and more agile so you can run for cover. I love it. I haven't tried it out just yet, but I might show you a quick war video when i get friends round.

War gun - Primary - 4/5. It has a reasonably large magazine, but not enough to hold out very long. Because it is not removeable, each of the yellow rods have to be loaded in separately, or else in a clip with a post it note on the side. The power is great for primary, and this should be formidable.
War gun - Secondary - 5/5. The storm 221 V2 has incredible range for a mag fed gun. If you go to a window, in a tree, or on the ground with a bipod, you are sure to be a formidable enemy. I would use this as a secondary.
General - 5/5. I love it. I just play with it all the time.

You like this? Let's get building this beast, shall we?

EDIT: after i got #64 rubberbands, the proper range is 60 ft max.

Step 1: Handle, Trigger, Stock and Firing Pin.

Picture of Handle, Trigger, Stock and Firing Pin.

This is a large step, so pay attention to the pictures and check what you are doing.
1) Build this part.
2) Close up on Firing pin.
3) Build this part too (sorry about the shadow).
4) Add these to part 3.
5) Build these parts as well.
6) Add them to Part 3
7) Complete the stock, and build the part in the corner.
8) Add this on to complete the step.

Step 2: Body and Barrel, Part 1.

In this step, you will Build all of the necessary parts that will go inside of the gun to fire it.
1) Build this twice, one without the orange connectors or bluerods.
2) Build these 3, and get a green rod.
3)Put this on now to save complications.
4-7)Build this. Hopefully you can see what is going on.
8-9)Build this too,
10)Put it on!
11)Build this.
12)Build the noted bars.
13)Attach grip
14) Build the barrel. When you put it in, you can put spacers on, but they aren't needed.
15) Finish by adding the barrel and the sight top.

Step 3: Body and Barrel, Part 2.

Just put the side on the thing you have just built.

Step 4: Connecting the Halves.

Here, you will have the majority of the gun finished. Good luck!

Step 5: Bipod (optional).

Picture of Bipod (optional).

Build all you see in the pictures. I found out, if you replace the orange connectors that connect the bipod mount to the grip with hinge connectors, you can fold this in to keep it compact. This is purely optional, you don't need to build this if you don't want to.
1)Build the Bipod Base.
2)Attach to the main gun.
3)Build this too.
4)Complete the Bipod.
To work the bipod, Move the yellow connector with the green rod on it up to close it, and down to open it. Have fun for a while, looking at this amazingly awesome device. Then, remember there is still one step to go. Keep going for about... 5 minutes more, then proceed.

Step 6: Banding the Gun, Loading and Firing.

Picture of Banding the Gun, Loading and Firing.

Collect the rubberbands in the picture. There should also be a small thin one there, but you can't see it. Put the rubberbands where you see them in the picture.

I almost forgot, put this blue rod into the gun behind the sights for strength... I forgot to put it in, lol

.To load the gun, place some yellow rods in the magazine. I find that about 5-7 work best, but I wouldn't do more than that, because the mag pusher will bend and break.

Then, pull the firing pin on the right side of the gun back. The trigger should lock, and the magazine pusher will go up a bit. Pull the trigger, and watch the mayhem take place!

Thanks for looking at my instructable, and building my gun if you did, good luck and have fun with the gun!

i like but show more and a list of parts

XxMechTechxX (author)2011-09-20

what the heck it keeps jamming the mag seems uneven one bullet jams the other every time i cant fix it

XxMechTechxX (author)2011-09-20

so again are you a lefty are you a lefty Jamalam

The Jamalam (author)XxMechTechxX2011-09-20

I'm righty, I just prefer having the bolt close to me so i con't have to take my hand off the handle, i can support guns using the stock and handle, and the foregrip isn't as necessary.

XxMechTechxX (author)2011-09-20

hey Jamalam are you a lefty because i am and this gun is perfect. i always get fristrated because the bolt is on the other side and i have to spend an hour trying to put the bolt on the other side...(im getting ahead of myself) So again

Are you a lefty

old chilly (author)2009-07-17

An Villain (author)old chilly2011-07-22

No, This is child's gun. You are going to need MUCH BIGGER GUNS!

shieldsam (author)old chilly2011-01-22

Furloy (author)old chilly2011-01-04


The Jamalam (author)old chilly2009-07-18

Wow, hell yes! You have to otherwise I will find you! jk ;)

old chilly (author)The Jamalam2009-07-18

skyfaller (author)old chilly2010-11-17

Hmm, im guessing you took this from somebody elses pic, Example Google.

Then, you posted it and said it was yours, because stepping on that accidentally is pretty hard.

shieldsam (author)old chilly2010-11-16

1 word:


I like it.

out of curiosity, is it just a gatling gun that you can hold? Cause I know they take forever to load.

Merugop (author)old chilly2009-09-18

Looks like the bazooka from Gears of war and its waaaaaaaaaaaaaaaaaaaay to big

Lowney (author)old chilly2009-09-06

How many barrels does it have?

mr.guy (author)old chilly2009-07-20

I just drooled all over my key board

MiniBr1t (author)2011-06-18

u said this gun was good yet when i made it, it wasnt working very well, i followed every step and built it all correctly yet nope it didnt show anything good mine shot about a couple of metres

The Jamalam (author)MiniBr1t2011-06-19

This gun works fine when it's built correctly. I can't help you if you don't give me a description of the problem.

shieldsam (author)2011-01-22

ive made a mod for removable mags, should i post?

The Jamalam (author)shieldsam2011-01-22

By all means, I've been looking for something like that. Thanks :)

shieldsam (author)The Jamalam2011-02-12

youtube vid here, modded beyond recognition. :)

shieldsam (author)The Jamalam2011-01-29

update: ill post it when i get a chance, just editing video for youtube. link coming soon.

shieldsam (author)shieldsam2011-01-23

I would post, but I need to perfect it slightly. The yellow rods in the mag keep getting caught, so can you give any tips. What rubber bands did you use on the pin?

knexsniper1 (author)2009-05-23

that magazine, can it accomodate yellow rods? also, what about it is not removable?

The Jamalam (author)knexsniper12009-05-23

It's made for yellow rods, and you cant use it like you would an uzi clip or handle magazine. It is a fixed inside internal one, like early rifles. Take the KAR98K for example. Its magazine is fixed inside. You load in the shells separately or on a stripper clip. This is like that.

DJ Radio (author)The Jamalam2009-05-25

lol stripper clip

DJ Radio (author)The Jamalam2009-05-29

sorry, it just sounds.... eww.

Vynash (author)DJ Radio2009-05-29


knexsniper1 (author)The Jamalam2009-05-25

oh, ok

Furloy (author)2010-07-24

im sorry jamalam but this does not work. i built it and the orange connectors ontop of the mag(the frontmost one) keeps getting in the way and when it doesnt the bullets dont leave the barrel. i am giving it 0.5 because a gun can look good, but when it doesnt shoot it is bullsh*t.

Furloy (author)Furloy2010-07-24

EDIT: ok sorry a peice in the mag wasnt snapped in and now it shoots like crazyness thanks jamalam gun rocks five stars!!!!

PieMaster777 (author)2010-07-06

awesome gun, i dont believe the second no is a con tho lol

joey99 (author)2010-06-29

Love the funny bunny

joshualater (author)2010-03-04

how do those to yellow rods connect to the legs of the bipod? ( I don't have those weird orange pieces so i dont know what they do)

The orange piece is the same thing as a yellow half circle. its just got a little nob on the flat part. there is a white rod with a gray connector on it. the gray connects to the yellow. :D A Little late i know.

MiniBr1t (author)2010-06-13

it jams all the time and i cant even get it too shoot 40ft wtf how can u even pull the thing back

MiniBr1t (author)2010-06-12

do u need the light grey connector cause i cant really see how it goes on

MiniBr1t (author)2010-06-12

hey when r u posting the secret project or have u already

Jesus. (author)2010-04-03

"Cockage" LOL!!!!! :-P
(sorry I had to)

camka14 (author)2010-02-07

Whats the piece count?

matrix828 (author)camka142010-03-05

2nd. lol

rec0n (author)2010-02-05

I just built this gun, and it's great.

FlutterTree (author)2010-02-01

OK, I'd like to have a word with the smart a** who came up with the whole "cocked" thing.

FlutterTree (author)2010-01-24

I find that it's a good thing that this gun hurts when it hits you 'cause when I have knex wars my team might get outnumbered but the other team will cowar in fear if they know the gun stings when it hits you... MWAHAHAHAHAHAHAHA!!!

finmonster (author)2009-12-05

post a peices list and ill make and rate 5*
