Picture of Knex RBG: Plasma pistol
Real plasma pistol.tiff
 A Knex repeater RBG, resembling the Halo Plasma Pistol.
Plasma Rifle
Pros:
-Semiautomatic
-Comfortable
-Looks and fires like the Halo Plasma Pistol
-Small and light. Hide it in a hollowed out textbook :D
Cons:
-Not really semi-auto since it may occasionally fire a burst of two rubber bands, even if the trigger is pulled once.
-Uses a modified piece.
Suggested use: Primary/ Secondary RBG
Similarities and differences between Plasma Pistol (according to Halopedia)
-Both may not fire projectiles when low on ammunition (this one may not fire if the rubber bands are too long, or not enough are loaded).
-Both are semi automatic 
-Both have a similar shape.
-Accuracy is similar.
-Does not home in on a target.
-Half the length and height of the real plasma pistol. 
-Only holds about 10 projectiles, not 200 (If you think of this as shooting overcharged bolts, this is a similarity)
-Both have the potential to stun (when aimed at the face for this one)

I dont like things like this breaking your pieces to make something you'll keep for about 2 weeks
charge11595 (author)  Fr-Pa-Co4 years ago
I have nothing against your belief and totally agree with it. I have a used (preowned) set of knex, and any broken pieces I use were already broken by the previous owner. If you have broken pieces already, why not break them further to make the useful?

well, it took a while to make but its finally done, i also made the heat vent and got that working 2. now i have a plasma pistol, a plasma rifle and my own custom energy sword whish is far sturdier and better looking than any others on the internet (no im not boasting, im just saying)

that took me ages to make cus instructions arent very good but AWSOME gun
do you have to cut the peices
charge11595 (author)  knexinglemon5 years ago
Yes, unless you can think of something else, like biting them into the right shape... :P

I think i would love this gun but, the instructions are so confusing, need more angels.Thanx=P
charge11595 (author)  DutchxGuy5 years ago
You should see my plasma rifle (CLICK HERE). If those instructions are easier, i could change the plasma pistol instructions to be similar to the plasma rifle.

 i have made this and modded it to have the "OverHeat Lid thing" when you have empty plasma (no more ammo loaded) the top will pop up, when you load a rubberband it will go back down!
charge11595 (author)  SonicX 225 years ago
 COOL! Please post a pic and send me the link!
 its kinda easy to make.

i can try to tell you because i took it apart due to low rubberbands (only about 3).

1 get 2 green connectors and 3 yellow rods and 2 Y Connectors.

2. slide the green connectors on both sides on the blue rod thats above the trigger.

3. attach a yellow rod on each green connector so its facing the front of gun.

4. attach a Y connector on each green connector so its facing the top.

5. attach the last yellow rod on the Y connectors.

6. get a strong rubberband

7.load it on the gun NOTE: the rubberband must go over the yellow rod.

8. shoot.

if the steps was too hard then il make this gun again and show a picture
charge11595 (author)  SonicX 225 years ago
I'm not too sure i got it please show me a pic, and ill add it to my ible.

vog1155 years ago
how do you put the trigger in
This step is very confusing. can u add a pic from a different angle? can't understand the one that's top-down. thx
charge11595 (author)  llamadudeguy5 years ago
Sorry, but my camera is out of battery, and I can't fin the charger, so I can help you nor post more instructables for a while. Try the last pic. If that doesn't help, maybe ask someone else.

Dude, what would be cool if the top folded up(in-game reference) and that how you reload.
charge11595 (author)  davison1125 years ago
 SonicX 22 made that mod in a comment above.

charge11595 (author)  KnexFreek5 years ago
 Thanks, but I need to upload a video of how to reload; )
please explain the visual similarities between the in-game model and this.
charge11595 (author)  Landon Sullivan5 years ago
Try downloading the free trial or demo of "Halo: Combat Evolved" and see for yourself. :)
News flash, I have the full version, and this looks only moderately similar.
