So I was bored and I threw this together. You should easily be able to build from the pictures...nothing too special about this gun.

Pros:

Real size

Really comfortable

Looks?

Stock (IMO)

Cons:

Old style gun

Not an internal push mag

Mediocre range

Mediocre accuracy

Mediocre overall

Step 1: Pictures

They need to fix the ease of uploading from a smart phone

Step 2: Updated Sights/mag

I changed the sights so they look better, and I added orange connector with y connector to stabilize it. It was wobbly before.
