Introduction: B.Z.A.R.

Picture of B.Z.A.R.
This is my Assault Rifle, the BZAR. It features a removable speed loading mag, meaning that the mag can be pre-loaded, and then inserted into the gun. The Speed Loading part means that the mag can be loaded without ever taking out the pusher, or pulling off the bands. This makes this gun extremely fast to reload; just pull off the empty mag, and clip in a new one. Plus, if you're out of mags, they're easily reloaded, or you can just push four more bullets into the chamber, and use it as a micro-mag.


  • Size: 15.2" x 5.9"
  • Range: ~ 30-40 ft.
  • Accuracy: Consistent
  • Pc. Count: Med. High
  • Mag Size: 7 (11 with extended mag)

The cameraman (author)2012-06-16

james4 (author)2011-04-15

i know what b.z.a.r. stand for big z's assault rifle

matsermetsuiker (author)2009-12-23

 good gun!
but the gun isn't good for long range shots

Big Z (author)matsermetsuiker2009-12-23

Thanks man! Try putting a couple more bands on for extra range, it can handle a fair amount of pressure.

rootbeer96 (author)Big Z2010-11-11

i made iron sights mad beast u have pistol sights or rifle by one attachment

Merugop (author)Big Z2009-12-28

 lol i cant get the ramrod in place with 6 rbs

Actually, you could make a stock that slots into the bottom of the handle if you make it completely hollow in there, and have the grey two-slot be a yellow to attach it firmly.

mettaurlover (author)2010-08-06

Made one; I now have a slightly oversized pistol-I only made it to the mag and a white and red past that so it has some accuracy. Great range, but I'm almost out of parts to use as ammo due to mag size.

MegaMetal8 (author)2010-03-23

im gonna make dis tonight


K1TK4T 117 (author)2010-03-19

jackdb1998 (author)2009-08-15

best gun that I've made!!! I have been looking for a gun with a mag like this for weeks

 me too

Big Z (author)jackdb19982009-08-15

Thx, i'm glad you found one!

jackdb1998 (author)2009-12-21

ive recently been running low on knex pieces cos i have used loads on my new chain gun turret and i have taken apart nerly all of my other guns but i refuse to dismantle this bcos its just sooooo gooood!

if u havnt made it yet then  make it now

Alien Terminator (author)2009-11-28

 Can I make a suggestion?

Have the ram rod be sharpened. If the ram is not sharpened and there is too much power, the ram rod will slide into the grey connector and the two pieces will be clipped together. That means taking apart the gun, and fixing it every time. A sharpened rod would not clip into the grey connector.

That's my advice, but it's only for those who want it.


J Moneyman (author)2009-09-06

stuff to do: stick it in ur mouth and pull the trigger and see how strong it is!

knex_mepalm (author)J Moneyman2009-10-21

I shot my right leg with over 300 knex guns to test the power, so far the highest is sr v2. It hurts. Because most of the range of knex guns is floating range which means it doesn't hurt after a few fett.

altair ibn la ahad (author)2009-10-03

whats it shoot

Big Z (author)altair ibn la ahad2009-10-04

Grey clips

J Moneyman (author)2009-09-06

looks comfy!

Big Z (author)J Moneyman2009-09-07


knexguy (author)2009-08-15

I like the handle, I think Extreme Builder made a gun which loaded via a mag and the handle? Could work on this.

smilee (author)knexguy2009-08-24

No banana inventor I think. (been a long time since I could say his name!)

Big Z (author)knexguy2009-08-15

Yes, if modded, the handle could be used as a spare mag, you'd just have to pull the ram farther back. NikAwesomes NASA can be used that way too.

chopstx (author)2009-08-14

wow! this gun is great! i think it would be better if it had a stock...... this gun truely is bzar! 4*

Big Z (author)chopstx2009-08-15

Lol, thx

chopstx (author)Big Z2009-08-15

do you think you could try to add a stock? if not i am gonna make one.

Big Z (author)chopstx2009-08-16

There's really no room to add one, if I kept the pistol grip it would be in the way of the ram, and the connection point would be too weak anyway. If I used a rifle grip, the handle would be too angled, and your hand would be in the way of the ram.

chopstx (author)Big Z2009-08-16

oh. i see. alright, thanks anyways!

Bartboy (author)2009-08-15


Big Z (author)Bartboy2009-08-15

Thanks, whats with the "....."?

Bartboy (author)Big Z2009-08-15

Could be better, but it's still cool.

Big Z (author)Bartboy2009-08-16


cerj (author)2009-08-15

reminds me of the R700 bolt-action sniper

NickAwesome (author)2009-08-13

Good Man.

Big Z (author)NickAwesome2009-08-13

Good Man Indeed.

knex_mepalm (author)Big Z2009-08-14

how does the removable work

Big Z (author)knex_mepalm2009-08-14

See step seven. It uses clips to hold it in, and a pin to release the bullets into the chamber.

knex_mepalm (author)Big Z2009-08-14

thx i made it and its awesome!!

Big Z (author)knex_mepalm2009-08-15

Np, and thank you too!

Big Z (author)cj814992009-08-14

Oblivitus (author)2009-08-14

Nice handle, it's a cool gun too.

Big Z (author)Oblivitus2009-08-14

Thanks, I was tired of sticking extra parts on the sides of handles, just so they would be comfortable.
