Introduction: Atchisson Assault Shotgun (AA-12)

Picture of Atchisson Assault Shotgun (AA-12)
Hey guys. This is (obviously) my K'NEX Atchisson Assault Shotgun (AA-12). This gun has been attempted at once or twice by other K'NEXers, like Seleziona, but has never really been done. So today I bring you mine. I am not going to say that it is so much better than Seleziona, because that is for others to decide, but I want to offer this for you guys as an alternative. =D

This gun, first off, is fantastic. It shoots probably 60 ft. (slugs, not shotgun shells), feels great, and is nice and hefty. It has some similarities to Seleziona's AA-12 (see here) but mine is mostly out of my head. Mine is quite a bit more accurate than his was, considering he had no fake barrel, his sights were..weird, and his had no trigger guard (which is something I have noticed in many of his guns). But, anyhoo, lets move on to pros and cons...

Seleziona: AA-12
BlackShadow12: SWAT 556 (his drum mag)

Good range: 60 ft.
Great looks (just compare it with the pics of the real thing)
Nice 'n hefty
Has fake barrel
Sights work nicely but...
Gun is comfortable to hold
Has fake CH (Charging Handle)
Handle is comfortable
Has GREAT details, like the bump on the trigger guard, and has triangular-like handle guard
About the right length
Has drum mag

Sights are not entirely right
Charging handle could be better
Drum mag is not tilted...

All and all this gun is pretty cool (IMO), so tell me what you think. =D

:o so pwetty :D

Thanks bro. Why don't you post stuff?

I would be posting things but i don't have a camera or phone D: just an old DS and this computer (of course :3 ) and neither have a built in camera.

Ah, that really is too bad. =(

So it really stinks cuz i have a few thoughts of how i can make a pump action spas 12 with realistic mag D: If i had one id post a few pics of my ideas.

Hi, here are the pictures of my AA-12. I think i built everything right and it shoots pretty far, not tested ranges yet, sorry for the rubbish quality of the photos, as I do not have a decent camera. Tell me what you think, thanks again.

Dude, you should post a review of it in a separate 'ible, I think that would be awesome. =D You did a great job. =D

yeeeeeeaaaahhhhhhhhhh!!!!! all we need is a working drum mag!

didexo (author)CODawesome2013-05-18

Some guy named Vortex made one for blue rod.

True dat. Do you like the AA-12?

No. I love it for reeal

Good. =D

Very nice! Wish it had a real drum mag but it works fine. The intro pic reminds me a lot of the background I use sometimes.

Thanks man. =D

No prob. Since you made this, what do you think of the chances of a triple barrel shotgun? They're marketing one on the cover of Home Defence magazine (If I remeber right...)

nerfrocketeer (author)JonnyBGood2013-04-14

I think that's called a hydra... 8)

JonnyBGood (author)nerfrocketeer2013-04-14

Well that's a close Nerf concept of it. I think the Hydra has seven barrels, if I remeber the game correctly.

nerfrocketeer (author)JonnyBGood2013-04-14

Oh... I guess my mind was just boggled for fear of all the ponies and bronies watching me... <:(


JonnyBGood (author)nerfrocketeer2013-04-14

Don't worry about it, they don't bite.....much.

They don't bite.......but, it must be admitted, they do lick. *is now scared*

XD. I forgot that one! *Looks behind back*

Oooooooohhhh the TRAUMA!!! why are links always so dang TEMPTING!? my sane life is over... €(

Moar links!
this one isn't ponies, I promise)

Awww I can't watch it on my phone whatever it is. :( maybe I'm lucky... O.o

Well, it's sort of a combination between Rick Astley and Nirvana. They put the musical track of 'Smells like teen spirit' under the vocals of 'Never gonna give you up'

Runs with hands in the air screaming!!! AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!

The chances of a triple barrel shotgun? Well, in real life, it would be a great idea. In K'NEX...I don't know if it would work. You might get a triple barreled anything, but getting it to shoot "pellets" might be difficult.

Was thinking about the same. The mag part would be difficult as well if it used one

Please post

Sorry bro, but it is broken. I am glad you like it though. =D

Element Force (author)2013-04-15

omg thats the best shotgun on the site so far!!! even with drum mag awsome! I like it XD!!

Thanks man. I am glad you like it. =D

no problemo =D

Johnhall44 (author)2013-04-12

Holy crap. If only you could incorperate votus's(I think thats his name) drum mag into this =D

XD, glad you like it. =D Whose drum mag?

His name is Vortus, It could only use rods as ammo but it is neat, hard to work with though.

Ah, I see. Do you have a link for me?

Thanks. =)

I see dr richtofen gave you the link. Its a very interesting design to work with,I found that it works best on a gun like the calico carbine that has the mag on top. =D

The most difficult part of putting the mag on the gun is adapting it to fit, I managed to fit it it on my project a2 once and tried to turn it into a c mag but that didnt work out too well.
