Introduction: "Project Nine - RX"

Picture of "Project Nine - RX"

Check my Sipriani Rifle V2 too!

Here it is!
My mysterious, new, Project Nine Reversed C-Bow!

Range is about 60 to 70 ft!
It functions great and looks as it works, fantastic!
This idea for a reversed crossbow started about 6 months ago...

I already had a Project Nine lying around but it was ugly, it failed to work sometimes, and the handle wasn't anywhere near comfy.
This one is the best version yet!
Heres some pro's and no's:

-Crazy Range
-Looks great
-One or two handed use
-Small for it's power

Sights are only accurate at a small range (10 ft)

You likey?
Lets get to building then, shall we?

Step 1: Handle

This part is needed since the trigger is stuck to the handle, so build it!
Build it once.

Step 2: Supportive Parts

These are needed for added strength,
Making it more durable.

Step 3: Sight

This one is just for looks.
Not needed for added strength or something.

Step 4: Trigger

The thing that holds the bullet in place before you want to shoot it.

Step 9: Supportive Parts (2)

Build it twice.

Step 10: The Rubberbands

These are the best ones for the job.
Get these and it will function perfectly.
You can use other RB's but it will function the best with these.

Step 11: Assembly

how do u fire it?

Kona-chan (author)2013-06-19

try next time to put a better sight on it,
The sights are lazy and aren't that good
try a scope or something

BleSam112233 (author)2013-06-17

How, exactly, does the reversed crossbow method work? ~BleSam112233

beanieostrich (author)2011-04-04

Hey Viccie.B1993, That gun is very EPIK =D I usd it as an uspiration for my Reversed Crossbow Pistol. You should see mine =D

didexo (author)beanieostrich2012-06-03

How do you know thats Viccie.B1993?

beanieostrich (author)didexo2012-06-03

All he did was change his name. And the original comment makes me look immature, so many caps locks and smiles in it.

Skreetsha (author)beanieostrich2011-04-20

Cheers! :)

wabawaba (author)2011-06-13

I build it than converted it to a oodammo pistol

Darthpuppy (author)2011-06-04

Wow, that is unrelated.

glugnar (author)2010-09-06

anyone else notice he has a hard time showing how to make each step?

Skreetsha (author)glugnar2010-09-19

You try 'n make a good Instructable, then you can complain.

glugnar (author)Skreetsha2010-09-29

hey its not my fault you cant show how to build each thing better

Skreetsha (author)glugnar2010-09-30

It isn't my fault you're a naggy prick either.

glugnar (author)Skreetsha2010-09-30

im not naggy i just state the facts

DJ Radio (author)glugnar2010-10-02

It's not a fact, it is opinion- I find the instructions clear and I can easily build this gun with them.

glugnar (author)DJ Radio2010-10-03

no its a fact that i think they are bad instructions

The Jamalam (author)glugnar2010-10-24

It's not actually. It doesn't take a genius to comprehend these, and you are clearly below average intelligence if you find it hard to build this.

glugnar (author)The Jamalam2010-11-05

No I'm not have you ever thought I might have a seeing problem?

The Jamalam (author)glugnar2010-11-07

Well then, you should have problems seeing all instructions in which case, and have no reason to moan at viccie.

Skreetsha (author)The Jamalam2011-04-21

Lol, thanks for sticking it up for meh :P

The Jamalam (author)Skreetsha2011-04-22

No problem :) How are you?

Skreetsha (author)The Jamalam2011-04-23

Good, despite the fact i have my main exams coming up in about 2 weeks.
Shaking the f*cking pulp out of me it is :S
And you?

The Jamalam (author)Skreetsha2011-04-23

I've spent this entire easter break revising because of my exams :/ Next week I have 2 extra days off so I'll be using those to revise too, and then the week after I have exams. It's a bad system in my opinion.

Other than that, I'm doing ok :P

You done any knexing lately?

Skreetsha (author)The Jamalam2011-04-23

Nahh, i've become a real Motorstorm addict.
And LittleBigPlanet 2 for that matter :P
At the moment i'm recreating vehicles from Motorstorm on LBP2, then make some tracks for 'em, make a main menu that takes you to the levels, and blamo! Promote it on and i might just get it MM-picked.

killersir751 (author)glugnar2010-12-12

i have a problem with my left eye (can't see completely out of it),
yet i could easily build this (in 2 hours (i'm a slow builder but fast learner))

DJ Radio (author)glugnar2010-10-03

It's a fact that you THINK they are bad, but the thought that they are bad is your opinion.

Skreetsha (author)DJ Radio2011-04-21

Pro's got each other's back ey DJ? :P

DJ Radio (author)Skreetsha2011-04-22

Zomg you're back.

Skreetsha (author)DJ Radio2011-04-23

I've never left, i just 'stayed in shadows' so to speak :P
Any new guns mate?

Skreetsha (author)2011-04-21

Lol, thanks mate, scope isnt that good though, but good enough, hehe.


beanieostrich (author)Skreetsha2011-04-21

Scope made it look MUCH better (in my opinion)

Knexman15 (author)2011-03-17

this is AWSOME!!!!!!!

Skreetsha (author)Knexman152011-03-18

Why thank you :)

glugnar (author)2010-09-06

you mean the trigger?

rrr67 (author)2010-01-24

omfg this is the hardest part.              


DracoUltima (author)rrr672010-07-23

not funny.......

redmaker (author)2009-03-26

do you like linkin park?

H1T4TCH1 (author)redmaker2010-07-14

i do like it ;)

Pizzapie500 (author)2009-08-18

Omg this is probably the hardest part of making it.


ol987986 (author)Pizzapie5002010-04-07

i havent got enough pieces i mite stop making the gun because of this step...

Pizzapie500 (author)ol9879862010-04-07


ol987986 (author)Pizzapie5002010-06-04

oh boy do i get a cookie?

knex shooter (author)2010-05-09

 Viccie - this or your NB-4, they both look good... but what in your opinion is better ? 

Dirtyboyy (author)2010-03-15

it's good .. bud change 90 to 95 ft to 60 to 65ft ..
because the rod can't get take much rubberbands ..
max 3 .. so 95 feet can't be reached ..
i don't want to slash this gun because it's a good gun ...
it's only the range .. bud i give you 5*

sprout_less (author)2009-09-06

4*s because i did not get anywhere close to 90 feet range

Pizzapie500 (author)2009-08-18

Lolz i had to put 3 #64 rubber bands how do u strech the rubber bands so far?

mettaurlover (author)Pizzapie5002009-08-28

Pizzapie500 (author)mettaurlover2009-09-02

Oh i thought he used #64s

mettaurlover (author)Pizzapie5002009-09-02


am_gers2k7 (author)2009-01-22
