Video is not working right now(at least for me).  Just right-click and hit "watch on YouTube"

The R-SAR (rail-system assault rifle) introduces a new type of firing system: the knetix rail system. This system is rubber-band efficient because there is less friction between the bullet and the barrel, because the bullet does not come into contact with the other ammo and most of the barrel until it is fired. Unlike other guns, this one uses more of a bolt system than a ram system, meaning there is nothing sticking out when you load it. It is very fun to just play around it.

Updates include a safety, more efficient barrel, and a more efficient trigger system

-contained firing pin
-good power (50-60ft with the rubber bands i used; you can use more)
-very original
-sounds SICK when you pull back the bolt
-8 round mag
-very accurate

-bolt will snap if too much pressure is put on it
-uses 3 broken pieces



Step 1: Outer Frames, Supports, and Trigger *updated*

This step explains how to make the outer frames, the supports, and the trigger.

1. The two outer frames-make these
2. Make these
3. Connect with blue rods to form the stock/handle support (blue rods on handle do not have to be cut but it makes the handle much more comfortable
4. Support-any kind of spacer will work for the middle
5. Make these
6. Connect to form butt
7. Get these
8. Cut rods :(
9. Connect to make trigger
10. Attach supports to one frame, hold onto the other frame
11. Safety
12. Secure tan clip (pic taken after gun was finished)
Is there a piece count?
plzzzz can i probably buy on of these out of kex i rly rly wont this gun but i only have a box of 5000 knex parts and i used them up makeing my knex arsinal and this would be perfect for my set but i dont wont to brake them up ill pay anny thing lol
is it possible to short this to like a pistol?
Unfortunately no because its length allows the rod to accelerate and shortening it would result in dramatic loss of power.
the pictures and steps are out of order fyi
i fixxed it YAY!!!!!!
complex looking but very nice handle meh... but 4.5*
i've made it, it was very difficult but i got it, AWESOME man only when you load it he gets stuck between the two orange peaces ;D
BLAH! Can you help out with this? :l Cause the updated one ive noticed is different because of the trigger mechanism and stuffles. Im having a hard time figuring out the trigger, the 2 grey rods at the bottom of the gun and the barrel >__<"
Wait, you don't understand the pics, or it isnt working?
Why isn't this featured? Multiple times. 5*.
cool ! 5* and fav.
Thanks man I appreciate it!
dude i built the gun and the rods just go out of the sides of the magazine, and when i take the ram all the way back, the bullet doesn't load, beacuse its stuck behind the ram even when it's loaded all the way....... PLEASE HELP !!!!!!!!!! <br>
mine doesn't work properly :(. The &quot;bullet&quot; pops out from under the cut red rod :/
where do you buy knex?
http://cgi.ebay.com/KNEX-BUILDING-TOY-DAYCARE-26000-PLUS-PIECES-HUGE-LOT-/390220757249?cmd=ViewItem&amp;pt=LH_DefaultDomain_0&amp;hash=item5adaf83901#ht_787wt_754 There if you need any K'nex here's 26000 peices if you have $900 in spare change
try hoby city or knex.com
If this gun shrunk in the middle do you think you could fire smaller rods
&nbsp;the instructions are wayyyy difficult to follow.<br /> <br /> 0.5*<br />
&nbsp;Well no one else had a problem.
is the ammo SUPPOSED to not even get out of the barrel, or did I do something wrong?
my parents said i could have my knex back tommarrow and i could not get my own gmail
Took away your k'nex? Thats harsh.
i know :(
Wyd they take it away?<br />
to tell the truth, i actually cant remember!! That was awhile back and i forgit why!! It was probably something to do with school....<br /> <br /> LOL
oops i didn't look at the date on it :&nbsp;)<br />
&nbsp;no problem!!!
If it involved school, just become a threat to the stability of your house so they won't take it away. That's what I&nbsp;did. Enough types and sizes of tools to take apart a 747, minus the blow torch.<br />
Yeah. I could dismantle anything in my house. Easily.<br />
Yeah... Bad idea for <em>anyone</em> to piss em off; I have about a hundred pounds of wrenches and more pointy tools lying around in my room. I count the D-TAB as a tool.<br />
What?&nbsp;I use it as a shotgun seeing as I&nbsp;don't have the pieces to make the turrets on hand.<br />
why can't you get your own gmail? ill set up an accy for you on gmail, just give me the username you want and ill make it for you. also gonna need your name for accounting purposes.
coulds u do that for me????? thankyou sooooooooooooooo much idk u can make a username just use the word kevin and tennis thankyou sooooooo much ps respond to this in the morning cause i have to go to bed my parents are strict tonight srry... And thanks again . kevin
i messaged you with the link to make an account for it; just use that.
ok ill make one but my parents will wonder why they arent getting barrrages of instructables emails
just transfer your *current* account to the gmail account, then make a second account using your parents address. or, if that doesn't work(the making a second accy with the address) tell them that you made a free account on gmail so that their inbox wouldn't be cluttered anymore. they'll actually &lt;em&gt;thank&lt;/em&gt; you for making one if you normally get a ton of ibles mail.&lt;br/&gt;<br/>
begged my parents all day and they finally said yes!!!!!!!!!!!!!!!! ill make one tonight and ill email you the new email adress
you made it yet? i dont have anyone new in my contacts or a message saying you did...
No cause when my dad came home he dissagreed with my mom, then he yelled at me, and told me I could only use my moms :(
trust me:if your dad thinks you're not mature enough to get your own email, side with your mom. anyway, females will always win in fights against males; they don't have the equipment we do downstairs to kick...
The only time dads win is when your mom is actually supporting what you do.<br />
&nbsp;true dat
yyyyeeeeeeeppp.<br />
you don't have to send me amil; if you use the link i PM'd you, you'll be automatically added into my contacts and ill be added to yours.
