Introduction: The Basic Shot Weapon (BSW) + Mods

First of all I would like to thank TheDunkis for this idea. 

Basically, this gun uses a firing pin that is like a charging handle and the elastics are attached to the front. This means more realism. The yellow connector on the front of the pin also means that the pin can fire multiple rounds, not too far off one of Oblivitus' ideas for a mag-fed shotgun. 

Anyway, this is a great fun-gun, and is very satisfying to fire. I hope to make it war-worthy with mods, possibly make an underslung variant and a pump-action mech. It also kinda looks like a Covenant Plasma Weapon from the Halo Series. 

It is design for close-range Power, not blistering range. 

Here are the stats:

Range: 25-30ft from one band, any more and I risk self-destructing the pin
Spread: 4-5ft
Mag Capacity: 9 shots, 3 bullets each slug.
Length: 32cm

Features

>New Firing Pin Mech

Here is version 1 in action




Step 1: Main Body

Pretty Simple. Note the special joining technique on Picture 4.

Step 2: Top Rail

This top rail is super-strong, so follow carefully. 

Step 3: Bottom Rail

This has to be done in layers, because the middle layer has a hole for the trigger block.

Step 4: Handle

This handle uses a strange way to connect it to the body- Pay Attention!

Step 5: Trigger

Easy...

Step 6: Magazine

This is more tricky. The front of the mag will be loose, you will strengthen it later.

Step 7: Foregrip and Handle Guard

The middle layer is different- Pay Attention!

Step 8: Top Layer

The final layer, YAY! It is exactly the same as the bottom, just without the white/blue rods.

Step 9: Strengthening/ Extra Bits

These are crucial in order to keep the gun strong. 

Step 10: Banding/Loading

Look at how the pin is made, follow it exactly.
Use a small band on the mag.
Use a stretchy band on the pin.
Pull back the grey gears, and pull the trigger to fire (duh).

Step 11: Optional Stuff

These Y clips are optional, you don't need them, they just make the gun look better and smooth design up.

Step 12: Finito!!

Go have fun!

Step 13: Mods

I will post any of my mods and your mods here, just leave a picture in the comment box below.

CuddlesMcT (author)2012-06-29

i love this, mainly because it looks like a plasma cutter from dead space

TigerNod (author)2011-12-04

I built it today. I love it. I used it not in a war yet and I have no trigger time behind it, but I can tell you what I think about it.

Beutifull gun, sweet firepower. It shoots very far (1 64' RB) for a shotgun. Feeding does not always go perfect. But it is better than some other shotguns. Love the looks and feel, but handle is a bit short. A pump would make it even better but I think it is not nessecary. The problems other people talk about are there but there are always problems on guns and on shotguns even more. I like it, keep up the good work.

TheFoofinator (author)TigerNod2011-12-04

Thanks. I got real lazy at the moment so I might have a redo at this, and take on the suggestions of others.

author
TigerNod (author)TheFoofinator2011-12-05

I have a suggestion. That gears on the side keep falling off, because of the bands. That is maybe a problem.

author
TheFoofinator (author)TigerNod2011-12-05

I know, it is a problem. I hope to get rid of the firing pin altogether and replace it with a rail. Stronger and it won't nee those gear. I have had an idea in my head that may work.

author
TigerNod (author)TheFoofinator2011-12-09

I wish you good luck then. ;-)

author
TheFoofinator (author)TigerNod2011-12-11

I have made it, now it can take 4 bands, but as soon as one thing breaks, I fix the issue, then another part needs reinforcing, so it won't be up this week. I have literally had to gut it and rid of virtually all of the rail area, only the trigger remains off this one.

author
TigerNod (author)TheFoofinator2011-12-15

You are working hard on it, are you?

author
TheFoofinator (author)TigerNod2011-12-15

Yes, when I have time this week. The main problem is the fact that all the impact of the pin is on the 2 red connectors, meaning that the rail at the front has to made like a rock. I've tried using yellow and a white rod on each side to reinforce it, but the pin then doesn't let the ammo load right. I may have to completely redo the front end : /

author
TigerNod (author)TheFoofinator2012-01-02

If that is needed to make it work as good as you can, go for it.

Happy new year! ;-)

use a blue rod like seleziona did

author
mulletman6 (author)2011-10-06

Made this, thought it was really good, but it didn't really shoot very well :/

author
JJ8090 (author)2011-09-25

Well done for posting it and BTW its EPIC

author
Johnhall44 (author)2011-09-16

Another idea is that you cut paper caps into squares and glue them onto the back of the ammo so when you shoot it sets of the caps.i used this on a knex dragonov that shot yellow rods

author
Johnhall44 (author)2011-09-16

tie a short piece of string between the shots to limit the spread and make bola rounds

author
tubanator-2.0 (author)2011-08-17

I made this but since i didn't want a shotgun type weapon i made it single shot and i think my ram/bolt is different i opted out of gears for just rods. and my handle like moved up alot? maybe just me but i changed that and i have to say it shoots pretty good with 2 bands but the row of oranges like pops out alot on mine? any idea what it is?

author
knexinglemon (author)2011-07-09

when you pull back the grey gear does the firing pin stick out??

author

The back? Yes it does. You could make the back end longer so it doesn't but it then looks silly

author
apples!!!!! (author)2011-07-09

This is neat. I like its overall look, too.

author
james4 (author)2011-05-06

this gun + stock = epic knex shawt gun

author
TheFoofinator (author)james42011-05-07

Thanks man. Could you make a stock? I don't have enough yellow connectors to make one... Also this is designed so it is modifiable hence 'Basic' shot weapon.

author
jamesdude (author)TheFoofinator2011-07-04

I would but I probably don't even have enough pieces to make the gun itself. Lol.

author

When I get to make this I'll make a stock.

author
james4 (author)TheFoofinator2011-05-08

i could make a stock but i dont have a camera tht has usb connection D:

if you add a few mods and a stalk... you got a vector kriss.

MegaMetal8 (author)2011-05-18

Woo done

author
TheFoofinator (author)2011-05-17

Use 1. It may seem underpowered, but this mechanism can't take much bands, unless you super glue the grey gears and green pins on. I can't really help it though, I didn't design the mech. I only used 1 band in the video, so you should see what kind of range its getting (not much) It's a shotgun it doesn't matter.

author

Use epoxy or just somehow fuse the trigger pieces together XD

author
MegaMetal8 (author)2011-05-17

Building, just finished step 5. Ill try and have a picture by Friday.

author
MegaMetal8 (author)2011-05-15

Considering building, Are all 5 female sockets necessary?

I'Ve got 2

author
TheFoofinator (author)MegaMetal82011-05-15

The ones at the front may be necessary (this is the bit that takes the impact), but the rest can be replaced with greys, perhaps a little tape on the back to make sure the rails are secure.

author
MegaMetal8 (author)TheFoofinator2011-05-15

Ok Thanks

author
TheFoofinator (author)MegaMetal82011-05-16

Actually, you don't even need the front ones, seeing as they are held by the mag pusher's elastics.

author
MegaMetal8 (author)TheFoofinator2011-05-17

Ok may build soon.

author
TheFoofinator (author)2011-05-16

What was wrong? How many elastics?

author
Raz1r Knex Bull3t (author)2011-05-08

Hey, I built the gun and made an easier loading mech, do you want me to post pics of it?

author

Yes please I'll add them into the ible.

author


Here they are, but note the broken yellow connector on the mag instead of the orange, and make sure you switch out those yellow connectors at the bottom of the thing that flips out with red connectors. Also note the three tan connectors with the broken white rod in them connected to the two red connectors at the bottom at the mag, also string a rubber band through where shown. Also the orange connector with the green rod on it is the new ammo for the gun I made.

P.S. If you want to flip the thing out to load it you have to pull out the top white/black rod to flip it out and reverse it to lock the thing in place.

I'll add the pics. What are the tan connectors for at the bottom?

author

It keeps the red connectors separated from moving around to much. Plus it acts like a lock for the thing that flips out.

author

I'll get started on the pics right now. My mod uses two broken pieces that are needed though if you don't mind. The rest just strengthen the part for me.
