Introduction: KAP-40 (Build)

Picture of KAP-40 (Build)

Hey guys. Well, I got a really good response from my preview(s), so I decided to post. If you want to know more about the gun itself, see here. This gun is a ton of fun to shoot and to admire, and is effective and efficient...for a model. Oh, BTW, we NEED your comments here. Please post your thoughts, as mikeasaurus would want to here from you.

Step 1: Body and Internals

In this step you are going to build the body and the internal mech. This step ought not to be to hard, but if you ever have any difficulty, just ask. Keep the Image Notes in mind, as they will help you. Broken rods are required, but that ought not to be a problem.

Step 2: Cookie Break

Go ahead and take a break, you still have some building yet. Eat a cookie, play some video games...actually, I would never stop building, so I don't know why I'm asking you too. XD

Step 3: Pistol Grip / Handle

In this step, you will be building the not-so-comfy grip. It is a simple step, and you should not have to many problems. I don't see any super-blurry pics, but, again, if you have any problems, just ask. :-) Yes, this step requires 5 broken blue rods. Just break 'em, there always useful anyway.

Step 4: Magazine, Trigger Guard, and Extras

In this step you will be building exactly what the title says you will...the magazine, the trigger guard, and the extras (side plates and selector gears). This step is rather simple, and should not provide any problems for you as a builder. Get to it...Again, if you have any problems or questions, just ask.

Step 5: Banding the Thing...

In this step you will need 3 size #64 and two size #117 bands. These provide the trigger pull, the SMP pull, and the FP bands.

I do not have many questions and I love this idea, but I did want to say, it would be great if on your next tutorial you could have a little more words, on some I was a little stuck for a while because of a lack of words, but otherwise awesom

Well, I thank your for your support, and for your advice. This was one of my older instructables (posted back in Feb 6, 2013), but many of my newer posts have image notes (if you click on the picture you want to know more about, I might have a description that will help you out). Thanks again man!

Would build, but don't have hinges.

You don't need hinges. They are only there for looks.

What could they be replace with?

Anything you want really.

No, you don't need the hinges. =D

don't you have any other handle fed pistols?

Well I feel like I'm turning over to the dark side..... I got a hack saw blade and a pre broken rod. Time to make some new parts.

Just so you know I'll boring the handle mag design and the mech for a gun I am making. Credit will be posted as well, no worries.

Hey bro, good to here form you again. =D No problem, and technically, the handle "mech" is not mine, its BM's. You are not turning over to the dark side, you are turning to the age of enlightenment. XD

I don't know it was pretty dark in the tool box, they said they had cookies.... I didn't find any though...

Cookies? Where are cookies?!?!

Well to start, there's one on step 2, but that's just one. We're going to need many more than that so let's search this place!

Here ya go!


Walther MPL anyone?

Yes what? I have one built already, but it needs some little amount of work. I don't want to post it too quickly, because people seem to like guns more when there is a long wait between each gun.

Yes as in 'yes, do that'
Take all the time you need, don't rush it

Alright, I'll get to it. I have had quite a lot of time recently, that is why I have been able to turn out guns like one every 5 or six days. Do you think I'm posting guns that aren't good because I'm going to fast?

You're indeed posting fast, but the guns are of good quality, so I don't see anything wrong with that

Alright thanks.

BTW, hows that MP-40 coming along?

Already broke it up. Tried making something yesterday, but couldn't find inspiration. Then I tried something with a removable mags for shooting, but failed, as I suck at making removable mag, shooting guns >.<

Really? Why? Well, NVM. What about the MP5SD? Have you attempted it? I don't think you should worry too much about shooting guns, I don't shoot the guns I make much anyway. All I know about shooting guns is to make a mech that will allow the pin to hit the bullet... XD

Haven't tried it yet. I had to work today (and tomorrow) so I'll find some time after that, I hope, hehe
