KAP-40 (Build)

About: K'NEX gun builder here at Instructables. More or less retired from the community, but I still pop in now and again.

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!
