Introduction: MHMG

This is my Masterdude Heavy Machine Gun (MHMG). It is made for power and shooting a lot of ammo in not a lot of time. It shoots the same ammo as my MBSR and has a hi-cap magazine. It also has a large bi-pod and can have a strap.

Pros:
-Semi-auto
-Strap compatible
-Bi-pod
-Strong
-Trigger guard
-Large ammo
-Hi-cap magazine

Cons:
-Uses too many pieces for some

More Instructables by me.

Step 5: Loading and Firing

To load, take the blue rods at the ammo feed off and hook the rubber-band at the end of the barrel and the spokes at the back as shown in the images below. Then place the blue rods back into place and then load the magazine as shown with the ammo shown. Add the ammo pusher made in the gun component step as Part D.

Image 1: Standard ammo.
Image 2: Armour piercing ammo. White rod at tip can be sharpened but I advise against it.

Very good gun, looks creative and very good.
Also, I'm gonna buy more knex but all I have to spent is £20.
Where would you reccommend buying knex?
The actual knex store (www.knex.co.uk), Amazon or any other sites (I don't trus Ebay.

google knex user group, they sell every knex piece ever made for really cheap. i got about 500 pieces for less than £10

author
killersir751 (author)shieldsam2011-07-31

Awesome, thanks.
I will check it out.

Knex user group !

I have already checked out knex user group and they do have a few good deals/offers, I don't think i'm gonna buy any.
I'm quitting K'Nex and moving onto modding NERF guns/blasters.

Thanks.
I find garage/yard sales to be a good source but I don't know if you would be able to find any near you. I myself also don't trust Ebay but Amazon could be a good choice. I'd choose a tub of K'nex, not a set, and not one with those K'nex bricks because they are useless (well atleast for me).

killersir751 (author)Masterdude2011-07-27

You really do think like me, but I don't know anyone in the area that I live in that does garage/yard sales.
I don't find the bricks useful either.
I will try Amazon and try to find the best deal.

This is a really cool gun.How far does it shoot? 5*

Masterdude (author)~KnexBuild~2011-07-18

I'm not sure, I made it over a year ago.

Er... How does this fire more shots per second that any of your previous guns?

author

It doesn't. It just has a greater ammo capacity and shoots larger ammo (hence the "Heavy").

author
Fred the evil puppet (author)2011-04-22

Wait a minute, the RBG wheels only hold
8 shots. The mag hold about 30. Please explain?

author

If you keep on pulling the wheel back when loading, you can put more than one rubberband per place on it.

if it's semi auto it's not a machine gun...

author
Masterdude (author)Mr. Muggle2010-05-04

Well, it's my version of a machine gun. I tried to add a motor to it to make it full auto in a way but the motors I have are too weak and even when I modded it to 6 batteries from 2 it was to slow to be practical.

author

Is this a machine gun or not?!

author

If a machine gun is fully automatic, then no, however if it's a gun which can obtain a high rounds per minute and has a large ammo capacity, then yes.

author

I don't understand.. Is it semi auto, full auto or what?

author

It's semi, not full, auto.

author
Fred the evil puppet (author)2011-02-28

So you're telling me...
This is a powerful, non chain fed, good looking,
Mobile , not too many pieces Knex gun.
5* and if I could, 5000000*!!!!!!!

author

Well, I'd probably have to disagree on the number of pieces. It Does use quite a lot of pieces.

author

Not for me!

author
Fred the evil puppet (author)2011-02-28

How many shots in a mag

author

I don't remember exactly but probably about 30, more or less.

TheChemiker (author)2010-05-03

Sooo, another overdone rubberband gun, right?

author
Masterdude (author)TheChemiker2010-05-04

Ummm...Yeah.
I usually try to get as much power as possible out of my guns.

author
TheChemiker (author)Masterdude2010-05-04

With this is it power or size?

author
Masterdude (author)TheChemiker2010-05-05

Kind of both. Maybe not as strong as my sniper (MBSR), but it uses large ammo and it is rather large ammo.

author
Masterdude (author)Masterdude2010-05-05

Larger than most of the guns I make use except for my MBSR.

Millawi Legend (author)2010-05-05
