Picture of AP4 K`nex Gun by Oblivitus
K'nex Gun Name: AP4 (Assault Pistol 4)

Description: This is a small, sturdy k'nex gun that works flawlessly. This instructable will show you how to make the AP3, the AP4 mods are on step 7.

Influences: I designed the entire gun except for the back handle, which I took from Killerk's Magnum and then I modified it.

Power: 3/10
Accuracy: 6/10
Rate of Fire: 7/10 (cock and fire)

Size: 7"(inches)x11"(inches)
Capacity: 9 rounds (6 when attaching pre-loaded clip)

Features: AP1:Realistic Trigger, AP2:Detachable Clip, AP3:"Iron" Sights, AP4:Safety

1: AP4
2: AP3
3: AP2
4: AP1

You can build the AP1, 2, 3, or 4 depending on how many parts you wish to use. NOTE: THE AP4 PICTURES ARE ON STEP 7.

Step 1: Pictures Of The Magazine

Step 2: Pictures Of The Back Handle

This is the only part of the gun I took from someone else.

Step 3: Pictures Of The Barrel

2: The Support Rail With Iron Sights

BTW: Use duct tape at the back of the firing rod.

Step 4: Pictures Of The Trigger

1: The Trigger

You will need to use some sort of strong glue at the top of the trigger piece connecting the orange 180 degree connector with the tiny black, special connector.

Step 5: Loading/Cocking/Firing

Picture of Loading/Cocking/Firing
1: Pull the elastics off of the clip feeder.
2: Pull out the clip feeder and fill the clip with gray one slot, one k`nex rod hole, connectors.
3: Replace the feeder and then the elastic bands.
4: Hold on to the top of the clip with thumb pressed on the second blue rod from the front, on the top supports.
5: Pull back the firing rod pull.
6: Press the trigger while gripping the clip with other hand.

Remember that if you fire while there are no rounds remaining in the barrel, the top of the feeder will break because it will get hit with the firing rod.

Step 6: The Detachable Mag

1: Add a few layers of scotch tape to a short (3rd smallest size) blue connector.
2: Put in the side of the mag near its top.
3: Fill mag with 6 rounds
4/5: Pop the back, then the front of the empty mag out of the gun.
6/7: Pop the back, then the front of the full mag into the gun.
8: Pull taped rod out.

You are now fully reloaded!

Step 7: The AP4

1: Left
2: Right
3: Top
4: Bottom
5: Left Side Of Mag
6: Front Side Of Mag
7: Safety
8: Trigger

ur hurting ur own rating not good handle instructions either 1/2 star off
Oblivitus (author)  I3uckwheat7 years ago
It's pretty simple, it's KILLERK's handle, and plus you can make the bottom however you like.
I hate that when people can only make it from what you have presented to them, and they can't just make something on their own if they can't see the right pieces for something simple like... "I can't make the barrel because at the front I can't see if it's a yellow or an orange connector."
Oblivitus (author)  Trauts7 years ago
Yep, every gun I make from this site looks like a mod of the original before I even start messing with it, lol.
I modded the handle for the TBAP and the trigger, and it looks different, the rest looks the same, maybe other ppls mods are internal...
i can do somithing els i just was in a bad mood
Oblivitus (author)  I3uckwheat7 years ago

why is the bottom of the mag different?
Oblivitus (author)  ILIKEPIE3336 years ago
Will you be building this?
still haven't built it
Oblivitus (author)  ILIKEPIE3335 years ago
Lol, I don't care anymore, the AP4 is crap, I only kept this instructable to prove that I was the first one to make a pin pull magazine and safety.
Oblivitus (author)  ILIKEPIE3336 years ago
I made it thicker to make the outside pieces lock in place instead of only the middle pieces being connected, allowing for more flexibility, the way it was in the AP3.

This gun, my moddified version of Jollex's DD-27 v2.1 is soon to come!
Hwy Oblivitus, What is the best gun on this site that uses moderate peices? I need to build one for a war.
oodassault pistol by the jamalam, has everything, true trigger, looks, feel, mag, compact, sturdy, and lightweight.
sorry, the dunkis.
Oblivitus (author)  happybirthday6 years ago
Build my Beast Pistol or Ultra Pistol if you can't.
I forgot to mention it has to have a really good range
True trig?
Oblivitus (author)  Storm9506 years ago
My AP5 is coming soon!
Oblivitus (author)  Storm9506 years ago
It has better sights, the safety is easier to pull on, it is more powerful, it has a new chamber design that keeps ammunition from falling out of the barrel or into it to far, extra stabilization has been added at the back for the firing rod, the firing rod can now be cocked faster, and there are a couple of other small improvements.
when's it a-coming along?
Oblivitus (author)  Oompa-Loompa6 years ago
Probably after the Beast Pistol.
Oblivitus (author)  Oompa-Loompa6 years ago
Get used to that name, lol.
Sounds good!
Oblivitus (author)  Storm9507 years ago
I just finished my instructable on it, check it out.
Oblivitus (author)  Storm9507 years ago
Yep. It's in the red box. I covered the rest of the mechanism up to make it look more realistic.

looks a bit like a killerk magnum.
Oblivitus (author)  An Villain6 years ago
That' probably because it has the same handle. This was my first instructable by the way, the gun isn't very powerful at all, but I thought that it was at the time when I had nothing to compare it to.
yeah, the handle and the yellow bits on top look killerk-ish.
