Check my K.F.T 540 - DA too!

This is it!
My Auto-Loading Knex Gun!
The El Diablo Assualt Pistol R-45
This is one of the best weapons to use in knex-combat, since it's light-weight, one-handed and has a good long handle.
It has a non jamming mag with an internal mag pusher, decent range, (30 ft) and a comfy handle.
Now, i'm just gonna tell some pros and no's:

- internal mag pusher.
- 12 shots.
- reliable.
- great fun.
- pretty powerful.
- pretty accurate.
- looks cool.

- if not built correctly, it will have a few errors.

You Likey?
Let's build then, shall we?

Step 1: Mag Pusher

Picture of Mag Pusher

The original mag pusher wasn't good so pic 2 shows the jam-free pusher.

Step 2: Trigger

Picture of Trigger

this part is to hold the ramrod back, before it fires.

Step 3: Magazine

Picture of Magazine

This part is to hold the bullets while they're waiting to get fired.

The original mag wasn't good either so pic 2 shows how you make this gun completely jam-free!

Step 4: Top Part

This part is for strength

Step 5: Top Parts (2)

This part is for strength too.
build 2 of these.

Step 6: Handle

Picture of Handle

This part is for strength and for a firm grip.

Step 7: Thingy (???)

Don't know where this is good for...........
i guess only for looks.

Step 8: Barrel

Picture of Barrel

one of the longest building times on this gun, the barrel.
i guess you know what this is for.

Step 9: Ramrod

Picture of Ramrod

This part is to shoot out the bullets.
i recommend you use a invisible rod like shown since, they are stronger than greys and blacks.

Step 10: Assembly

If you have questions, ask them at the specific step.

Next Steps:

- (Re)Loading step - 11
- Rubberband Emplacements + Rubberband Mag Mod - step 12
- Mods - step 13

Step 11: (Re)Loading

Post a comment with the problem.

Max Capacity Mag: 12 shots.

Step 12: Rubberband Emplacements + Rubberband Mag Mod

Picture of Rubberband Emplacements + Rubberband Mag Mod

Having Trouble?
Ask it in a comment.

Pic 4 is the rubberband mag mod.
it will never stop lifting the mag when you put the bands like that.

Step 13: Mods

Picture of Mods

I already showed them but here they are again for some clarification.

Step 14: You're Done!!!

i cut my skin during the process of making it but your gun is the best ive made so far

imducky98 (author)2014-12-18

Skreetsha, someone on youtube made a video of this (video date Oct 25 2008) and yours is made by Oct 6, and this person claimed this pistol as his and its clearly not his because your date is older his date is younger and this persons youtube name is dirt661. (just letting you know)

elwoodknight (author)2012-08-26

Skreetsha (author)Millawi Legend2012-05-20

Now SkreetshaOfficial, i make music via LBP2. Lol

johnguackmbl (author)2010-06-24

If I was building this, could i not build the "for strength" parts?

MR.J67 (author)johnguackmbl2010-12-26

i made all the parts and followed all the step's to see how the gun fires and works. this is what i got " i wasent able to pull the ram rod back, and had a hard time with the trigger, everytime i pulled the trigger it would snap off and break" so i give this gun a 3.8 rate because it has a good shell but the intereor could use some work... good gun tho MRJ.67

Skreetsha (author)MR.J672012-05-20

That is not due to the way how it has been created by me, that is how it was assembled by you.

for the ammunition, i like the idea of it being pushed up, but it's a pain on my fingers to just take it off and then put it back on, especially in the midst of battle.

what i'm suggesting is a little hole, just big enough to put a rod in.
this makes reloading faster, and saves my fingers from so much punishment.

clara3 (author)clara32012-05-12

like, maybe this?

Skreetsha (author)clara32012-05-20

Yeah that works too. I for one don't even have it anymore, but I would've maybe suggested that as a mod in this Ible.


stevedude123 (author)2012-02-13

Timstoop (author)2011-07-25

Skreetsha (author)Timstoop2011-07-25

Cheers lad, keep on gunnin'

gbmaster137 (author)2011-06-07

first gun i build, took me about 4 hours to build thanks to how "well organized" my knex pieces were, and i also didn't have the pieces in the right color (the yellow connectors are grey in mine for example)and i haven't shoot it cause i have no rubber bands and no money to buy them

DaBoss459 (author)2011-05-26

hey guys, i cant figure out how you put that wretched orange peice on that jacked white peice, THE AGONY, I GIVE UP ON KNEX, !@#$% YOU, Viccie.B1993, thanks for killing my dreams, you crazy @#$%&!

knexman2001 (author)2011-02-06

Dude I built this and it gets jammed... alot

DracoUltima (author)knexman20012011-02-06

Clip off the end off the ram by about 1/2 a centimeter.

Shaitan666 (author)2010-10-21

r the grey pictures that 1 slot connecter with a hole or the 2 slot connecter 45 degree angle

loonley (author)Shaitan6662010-11-21


Killbunny (author)2009-12-12


I found the grey to be a very unsatisfying trigger, as its curved surface would not hold the ram rod back, rather guide it through. I found myself having to hold the trigger out to keep it from firing. SO, instead of the grey with the black "claw", replace it with an orange.

loonley (author)Killbunny2010-11-21

that is right and handy if you dont have the claws!

webby427 (author)Killbunny2010-02-20

use stronger/tighter elastics but good point

Superpoopa (author)2010-11-03

this was my first knex gun

jack3939 (author)2010-09-07

the triger does not work any ideas?

irock2009044 (author)jack39392010-10-31

The trigger system does work. Obviosly u made it wrong cuz I made it and it worked perfectly. Didn't need to mod anything either.

Shaitan666 (author)2010-10-22

i figured out the barrel but where doies the trigger go it doesnt fit anywhere it just falls out

Shaitan666 (author)2010-10-21

i dont understand picture isnt clear

Shaitan666 (author)2010-10-21

im having problems making the barrel the picture isnt very clear could u post another

knex1111111111 (author)2010-10-16

I used as an aimer.

knex1111111111 (author)2010-10-16

I'm done man. The entire gun is hard. Now you put this rocket science in?:)

bennyboy96 (author)2010-10-03

im out of them black pieces which connect the orange pieces at the top to the white ones. what else can i use?

footballdevil (author)2010-09-29

Just one word for : AWESOME

SDW071 (author)2010-09-18

How do you attach the trigger? I can't get the ramrod to hold still. it keeps pushing the trigger down. also ho do you load it? the blue rods keep jamming.

knex1111111111 (author)2010-08-29

I like it. Now my sister dosent bother me anymore.

jmm72 (author)knex11111111112010-09-03

iownu136 (author)2010-06-17

Skreetsha (author)iownu1362010-06-20

Why bother telling us, lol.

iownu136 (author)Skreetsha2010-08-11

felt like it! btw soz for the late reply

spijk860 (author)2010-08-01

I made this gun with a stock and a longer barrel that was not hard you have done within one hour

Skreetsha (author)spijk8602010-08-03

Ok, seriously, if you are gonna troll about you upgrading my gun with more friction and making it heavier, please just don't comment at all.
