My SAR-5 (Sniper Assault Rifle - 5)




About: I used to build K'nex guns. I'd like to think I've grown to be quite good at it, however, I've lost most of my interest in K'nex over my first couple of years in High School, but I do occasionally still come...
this is a gun i made in 1 day... i always wanted to build my own sniper rifle or assault rifle. i have tried a few times... 3 actually, but it was never even close to being good at anything (accuracy, strength, comfort, shape, range, sturdiness, size). last week i was just like on a crazy roll of building awesome guns (of my own of course, not from the internet), and i feel this gun is just the peek. i built 5 guns (including this one) 3 of which (also including this gun) i have posted instructables for (the first 2 weren't all that good (they were the SEGV-1, which i mentioned on the SEGV-2 instructable, and the AKG (Awesome K'nex Gun, although it turned out to be much less awesome than i thought it was))). i call it a sniper rifle because of its accuracy, shape and power; i call it an assault rifle because it has a magazine (a removable one too), it is very comfortable, therefore good in assaulting enemy bases in k'nex wars, it is also easy to load,  like most assault rifles, and also, it's shaped like one. i really like giving my guns 3 letter names (if there is a fourth letter and it is v for version at the end it still counts as 3 letters), if i can do it with 1 vowel, preferably in the middle, i would, and i like adding numbers at the end, sometimes telling what version it is, and sometimes just a number. in this case (5), i used my lucky number because this gun is my greatest creation so far and it is truly amazing ! i hope you enjoy this gun as much as i do, because i LOVE it !!!!

@@@EDIT: i made a v2 for this gun, i'm just not sure if i'm going to post it... the upgrade includes: a much sturdier, bigger, more comfortable stock/butt, a comfier handle, also a small trigger stop that prevents the trigger from all the way back and accidentally exiting the barrel, a much easier to load, bigger, stronger ram that can use more bands, therefore making it much much stronger (i got it to shoot 119ft this time) and increasing the accuracy by a pinch (because of the improved strength), and last but not least, i changed the ram guide a bit to fit the new improved ram.
if i get 10 comments asking me to post the upgrade, i will.@@@

@@@DOUBLE EDIT: i made a v3 including a whole much much better new magazine mech. the two most distinguished and most important changes are that the new magazine is now curved (cool) and instead of having to put a stick through the magazine every time you load it and insert it into the gun, now it locks and unlocks automatically with an internal mech. the idea for this amazing change i got from the "knex concepts" instructable by oblivitus. awesome idea by him, awesome result by me. check the instructable... it's awesome. like i said before, i'm lazy about making instructables so if 10 people comment asking me to post v3 (including v2), i will. (if you like the gun, comment... the v2 and v3 changes are simply awesome... you won't regret it (and yeah... i like saying awesome, 'cause i'm awesome))@@@

NOTE: the magazine is the same as the magazine in my A.R.M. Gun, which you can reach here . if you have any difficulties (which i don't think you should) with loading the magazine, or inserting it into the gun, you can also find out how to do that in my A.R.M. Gun instructable.

amazingly accurate (0.5 sq. in. from 13.5ft distance, 1 sq. in. from 30ft distance, and about 3 sq. in. from 50ft distance)
very strong (CAN cut perfectly through 7.... YES 7 (!) sheets of paper)
excellent range (got it to shoot 97ft with 7 doubled up regular bands @@@EDIT: 119ft with 12 doubled up bands@@@(imagine what it could do with #64 bands))
looks GREAT, shaped like a real rifle
removable magazine (my own mechanism invention, used also in my A.R.M. Gun)
very easy-to-use ram
mag-ram never ever breaks, it stops just before where the ram goes
real, non-breakable trigger
very comfy handle, angled 45 degrees
amazingly comfortable, easy-to-use and accurate iron sights
all of the gun is very sturdy
never jams
flat, smooth, and therefore VERY comfortable butt/stock, also placed at a very good distance from handle (not too far, not too close)
comfortable cheek rest for aiming
ram guard, makes the ram a whole lot sturdier
nothing ever breaks (so far at least, for me)
uses only 2 broken parts which are not a must
relatively (to a full sized rifle, that is) doesn't use much parts

uses a lot of dark grey/1-slot connectors
the 2 2-slot, straight connectors used for loading that are on the ram are not at the same level (one is slightly behind the other), and some people might see that as a bad thing (it honestly doesn't bother me at all, but, you know, criticizers...)
@@@EDIT: the new ram on the v2 uses a much better loading mechanism, therefore this con is no longer important.@@@

7. the gun from the top
8. the camera looking through the iron sights
9. 1st person view of the gun

@@@LAST EDIT: this is my last edit on this 'ible and/or gun. it's a video of the v4, the final version of the gun showing it's mods and it's superiority next to the previous versions.

5. attach like so (optional)
6 . attach like so (optional)
7. make these
8. make these
9. attach like so
10. attach like so
11. attach like so
12. make this
13. attach like so

Step 2: Outer Shell

1. make these
2. make these
3. get these (8 blue spacers and 2 cut grey rods (if you don't want to cut your rods, get only 4 blue spacers, and drop the grey rods))
4. attach like so
5. attach like so
6. put the blue spacers onto the rods at the top as shown
7. attach like so, keeping the blue spacers between the Y-connectors on both rods

Step 3: Stock & Cheek Rest

2. make these
3. make this
4. attach like so
5. attach like so
6. attach like so
7. get these

Step 4: Front Barrel

1. get these
2. attach like so
3. attach like so
4. attach like so
5. attach like so (this is one barrel unit. i recommend making 8, like i did)
6. 8 barrel units connected
7. on the unit one before last, on the top in the middle row of 2-slot straight connectors, don't put a black/green rod, and in the same place on the last unit, put a Y-connector as the front sight
8. get a lot of dark grey/1-slot connectors (optional)
9. add them on all of the blue rods to make the barrel stronger (after a few dozen shots, the barrel sometimes gets a little spacey, and that makes the bullets change course, making the gun much less accurate. you can just strengthen the barrel every once in a while, but i would rather do it this way) (optional)
10. on the first unit, attach 2 black/green rods and 4 grey rods as shown

Step 5: Ram & Ram Guard

1. make a very simple ram by connecting a ball joint socket with a grey/ black (preferably black) rod, and taping it tightly

3. make this
4. insert as shown

Step 6: Putting It All Together

1. this is what you should have by now
2. attach outer shell to main body as shown
3. do the same on the other side, and attach the top of the outer shell (the back sight) to the other side
4. get a band
5. put it on the trigger as shown on both sides
6. get these
7. attach like so
8. get these
9. attach like so
10. get these
11. attach like so
12. insert ram into back of main body and attach ram guard to outer shell as shown
13. double up two bands as shown
14. put however many doubled up bands you want on to the ram like so and attach on both sides as shown
15. another view of the bands
16. get these (7 2-slot straight connectors)
17. attach like so to back of ram guard
18. attach cheek rest to back of main body
19. attach stock to back of ram guard and back of cheek rest as shown
20. attach front barrel to the front (DUH !) of the outer shell
21. HURRAY !!! you're done !!! this is what you should have. for anything to do with the magazine, read the intro page description, and for any further help, suggestions, or anything you can think of, please comment on the intro page. also don't forget to rate, check my other instructables, and if you like my work, to subscribe to my account.

    It can't be because the gun uses low-caliber ammunition by knex standards. Most snipers use heavier high caliber ammo for optimum accuracy, and better penetration. In knex longer rods are generally more stable in flight for longer distances.

    ok... 9 more comments and i will... sorry it's just i'm kinda lazy and need some moral and inspiration to go posting more pics...
