Linkin's Lightning Carbine (LLC) | a K'nex SMG

This is the first gun I have ever made by myself, and I am so happy with the result. After about five attempts, I decided to make a machine pistol. That machine pistol turned into an SMG pretty quickly. Now, I called it the Lightning Carbine because...a weapon name generator online came up with it for me :P. Now for the stats:

• 6 inch pin (Excluding the connector)
• SUPER comfy handle
• Attachment rail at the bottom (Currently holding the grip here)
• Iron sights
• Small rail for sight
• Comfy stock (The bit that rests on your shoulder curves and is designed by The Red Book Of Westmarch)
• Removable pre-loadable magazine (Friction held)
• Trigger guard
• Shoots grey 1 slot connectors attached to a green rod
• 7 layers thick
• Sturdy
• - Stock wiggles a bit
• - Uses cut pieces (In the magazine and trigger)
• - Simple pin gun
• - Handle sometimes breaks
• - Sight rail obscures iron sights (When building this part of the gun, you can choose to have no attachment rail at the top, a single row, or two parallel rows)

I haven't included the range as I have nowhere to measure it and I have no idea how to measure it, however I speculate it can get about 30 feet.

Step 1: My Thought Process

At first I wanted a pistol, however I didn't want a handle magazine. After seeing some curved magazines, I wanted to use one of them, however I realised it made the gun look like an assault rifle. So I set about Instructables and looked at tons of internals of guns to get a feel for how to build mine.

I started with the internals of the barrel after the mag and build around that.

My next step was to make a magazine. I took a white rod magazine and modified it to be pre loadable. I also curved the base of it (which looks really cool in my opinion)

Next I made the internals fit the magazine, and started on the layers that encase the internals. This meant I could start work on the other wide of the barrel.

I started the internals (behind the mag) and the trigger. The trigger was great, until later on I shot the gun and the pin pushed the trigger out of the way.

I then built the handle, taking some inspiration from CorgiCritter, and attached it. It is EXTREMELY comfy!

I then went to work on the stock which I knew would be the hardest part. I started with the centre three layers and worked around them.

For the actual shoulder part, I already knew I wanted to use The Red Book Of Westmarch's curved bendy rod design and I worked around that.

After test shooting the gun and realising the trigger didn't work, I spent a LONG time getting a trigger to work, and eventually got a perfect one!

The whole gun was complete at this point. My first k'nex gun built by me alone. I was so happy and satisfied, even if it is a simple pin gun.
