The Bischoff 720 A.T.S (Accurate Targeting System)




About: Favourite games are LittleBigPlanet2 and Gran Turismo 5. Favourite music genre is drum and bass, but my current favourite song is Gorillaz - Clint Eastwood. I mainly build replicas of godly cars on LBP2. Su...

Check my Scorpion 360 C.D.M too!

Here it is: The Bischoff 720 A.T.S

This is my biggest and most sweet knex gun, and the shooting system is inspired on Killerk's firing system
It has a range of at least 175 ft and the accuracy is up to 110 ft!
I think it's my personal best because of the range.
Very fun when sniping on targets.


-Kick ass design
-Can pierce a bucket from a distance of 3.5 m
-True trigger
-Two handles
-Very accurate
-Very powerful


-The bipod isn't foldable

For short:
It's a very recommandable sniper rifle.

Step 1: Collecting Materials

12 greys
8 reds + 1 red (bullet)
7 yellows
29 blues
114 whites
108 greens

110 yellows
44 greens
18 light greys
28 oranges
22 greys
32 reds
6 whites
2 dark blue

1 tan clip
2 metallic blue clips
3 y-shaped connectors
8 blue spacers
2 gray spacers

Also needed:
2 rubberbands
1 snapped rubberband
1 small rubberband
normal tape
duck tape

This is what you'll need to make the gun.

Step 2: Upper Stock

This part isn't necassery but it makes the stock a lot more resistance proof.

Step 3: Bullet Holder

This part is for letting go of the bullet when you pull the trigger.

Step 4: The Barrel

The most time consuming and finger torturing part of the gun, but it's necassery.

Step 5: The Trigger

This part is very necassery, assuming that it locks the bullet in place

Step 6: The Bi-Pod

This part isn't necassery but it comes in handy when sniping because you will have a stable base to aim.

build it twice.

Step 7: Rubberband Shooter

This part is to tie the rubberband in place and so that you can pull back the band.

Step 8: Stock

This part is pretty important for looks, strength and, it makes a comfortable handling when shooting.

Pic 5 needs to be built twice.

Step 9: Barrel Bars

This part is required because if you would'nt put it on, the barrel would be all shaky and that's a less accurate shot, which is annoying.

Step 10: Handle Bars

These parts are for a more comfortable handling of the gun.
and they spare you some painful fingers.

Step 11: The Bi-Pod 2

Connect the two bi-pod sides as shown.

Step 12: Putting Together the Barrel

pic 2: bullet holder + barrel
pic 3: put them together
pic 4: barrel + barrel bars
pic 5: put them together
pic 6: rubberband holder + barrel

Step 15: Ammo

The bullet is a red rod with a tan clip on the front and duck tape on the back for some stabilising when in the air.

Step 16: How to Put on the Trigger-rubberbands

Put the rubberbands as shown.

Step 17: How to Load

Put the firing band behind the tan clip.
pull it back.
click it on the y-shaped connector.

    yo victor,can i use your siprani mech on a pistol im making, pretty plz?
    it has a range of 70 foot and ill give u credit in the intro

    After Building your siprani rifles and liking the simplicity of them i decided to build this one and i only have one thing to say about this gun...
    IT'S AWESOME!  first off i love the presure trigger i have never seen one of those incorperated into a knex gun before. The only thing that scares me is the firing mechanism, lets just say i have had tons of self inflicted injuries due to the miss fire of the sr- v1 LOL! but this one seems pretty stable with pressure trigger and all. Lastly how do you make those fins on the bullet? i have tried before to make them and they always make my bullet curve in the wrong dirrection.
