Introduction: El Asesino 750

Picture of El Asesino 750

Check out my new gun. This is a 6 foot, 3 inch knex gun that is capable of shooting 100 feet. It is very strong and I am only using 1 strand of rubber bands. If you were to use 2 strands of 25 rubber bands you could add more than 50 feet to the range. EVERY STEP IS 100% NECESSARY. WITHOUT A STEP IT WILL BREAK COMPLETELY APART. Please build this before you rate it. Comment and rate please. PS. El Asesino 750 means The murderer 75.0 inches. Yes I took all of the photos in my tent because I didn't have a big enough place anywhere else.

Step 1: The Stand/Bi Pod

Picture of The Stand/Bi Pod

This is absolutely necessary, no questions asked. It can be used as a bi pod too because it tilts forwards and can easily be controlled with one hand.

Step 2: The Barrel

And the longest step.

Step 3: Barrel Case

This is the outer covering for the barrel. Use my foot and the light so you know where you are when the camera moves over. It is confusing so it may take a while to build.

Step 4: Rubber Bands

You need 2 strings of about 25 to 30 rubber bands. WOW

Step 5: Connection

The best part.

Step 6: Loading and Firing

I do not have a picture but you need to move your hands in a pattern down the barrel passing the rubber bands back and forth untill you get to the bottom. After loading it 20 times I can now load it in under 30 seconds.

Why are you trying to copy the knex super sling on youtube? I dont think you saw it, but its better than this.

Can you post a video of it please

I think there was one on IAC's board. I found it. Here it is

TigerNod (author)DJ Radio2009-04-02

There is a very big difference. The el assesino uses a rail. The super sling has no rail (which is better because there is less friction) There is one thing I can say about the super sling. That Uber-Awesome monster of a knex gun has the best range of all knex guns so far. (and parhaps also the worst accuracy)

Bartboy (author)TigerNod2009-04-26

No. 350 feet of range i s not the best. There have been ones that shoot further.

TigerNod (author)Bartboy2009-04-27

Which one is the best then? How far does it fire? (I can imagine a knex gun that shoots over a kilometer, omfg)

Jesus. (author)TigerNod2009-05-04

benfoxg's B.S.R rapter shoot's 450ft!!

I_am_Canadian (author)Jesus.2009-06-02

With help of a rocket motor...

Jesus. (author)I_am_Canadian2009-06-02

no with the help of a rocket motor it shoots 1000ft with out the rocket motor it shoots 450ft

Electroinnovation (author)Jesus.2009-12-11

lies. Do you know how far 450 feet it? thats 1.5 football fields!! even a real gun has trouble shooting that far! it is phisically impossible for rubberbands to retract fast enough to shoot a porjectile that far. he obviously lies and anyone that made it exaggerated because thay thought it was a great gun.

Jesus. (author)Electroinnovation2009-12-11

Well, how about lowney's claim, that killerk's SR V2 shoots 500 feet, i mean come on. 

Electroinnovation (author)Jesus.2009-12-11

complete BS. I built it and i got about 100 feet. With a little tweaking i got it up to 150 feet but 500, never EVER going to happnen.

 Exact thing happened to me All his guns are bs

ok good im not crazy

I_am_Canadian (author)Jesus.2009-06-02

My bad.

TigerNod (author)I_am_Canadian2009-07-20

Lol, I understand what you are trying to say there Canada's guy :-).

I_am_Canadian (author)TigerNod2009-07-26


Jesus. (author)Jesus.2009-09-20

and killerks sr v2 shoots 500ft!!!!!!!!!!!!!!!!!!!!!!

An Villain (author)TigerNod2009-07-19

actually rails are better for accuracy.

TigerNod (author)An Villain2009-07-20

True. Did I stated that it isn't better for accuracy then?

An Villain (author)TigerNod2009-07-20

no, all you said was no rails are better for less friction, i am making a supplimentary statement, not a contradictory statement.

TigerNod (author)An Villain2009-07-20

Sorry, I understand now (Lol I don't even know what the words supplimentary and contradictonary mean but I think I can guess what it means)

An Villain (author)TigerNod2009-07-20

supplimentary means i add information to the sentence that is already there and contradictory means i disagree with the sentence and show what i think is correct.

DJ Radio (author)TigerNod2009-04-02

the 350+ feet range was because the gun was pointed at a 45 degree angle. I want to see it shoot flat.

Holy crapload of bad words. It is beautiful. Sniff sniff.

not mine.

Who made it then?

knexrule100 i think

idk. it wasnt posted here, only on youtube.

The Jamalam (author)DJ Radio2009-02-16

why? He didn't copy its completely different.

Acrually I have no clue whay you are talking about.

pls (author)DJ Radio2009-02-16


charlie farthing (author)2009-09-20

why have you yoused blue rods for the bullit chanel

to save pieces

mettaurlover (author)2009-03-29

hmm... when i get more knex, i might make a tank and use this as its gun...

That would be awesome, but it would have to be some big tank! lol A six foot gun translates to about an 8 foot tank.

barrax (author)mettaurlover2009-04-10

XD how... much...knex?!?!

mettaurlover (author)barrax2009-04-13

a LOT.

Miles Tails Prower (author)2009-04-17

May build and put some minigun-ish handles on it... Then I can carry it.

wehe-tehe (author)2009-03-12

Nice. You do know that was already brought up. Look below.

charlie farthing (author)2009-02-19

Electroinnovation (author)jollex2009-02-17

To some people but to others it is a great bargaining device as well as a huge powerhouse.

Electroinnovation (author)2009-02-16
