Introduction: The El Diablo Assualt Pistol R-45

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

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

Step 2: Trigger

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

Step 3: 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

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

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

Step 9: 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

Have problems?
Post a comment with the problem.

Max Capacity Mag: 12 shots.

Step 12: 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

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

Step 14: You're Done!!!

Well you've built yourself a El Diablo Assualt Pistol R-45.

Have freaking much fun with my knex gun!!!

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)

johnguackmbl made it!(author)2010-06-24

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

MR.J67 made it!(author)2010-12-26

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 made it!(author)2012-05-20

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 made it!(author)2012-05-12

like, maybe this?

Skreetsha made it!(author)2012-05-20

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.

gbmaster137 made it!(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

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 made it!(author)2010-11-21

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

webby427 made it!(author)2010-02-20

Shaitan666 made it!(author)2010-10-22

SDW071 made it!(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 made it!(author)2010-08-29
