K'nex C.A.R. : Compact Assault Rifle

Hi there.
My most recent K'nex creation is this gun, the C.A.R.
This stands for Compact Assault Rifle, which it would be, if it shot.
However, this is a non-shooting gun, I made when I was bored a couple of days ago.
It feautures:
- Moving charging handle and trigger
- Compact
- Removable magazines
- Sort of comfortable (my hands are too large for the handle)
- Foregrip
- Pretty good looks IMO
- A bolt catch (idea by The Dunkis
- A magazine release, closer to the trigger (but still behind the handle) (idea by The Dunkis)

That's about it.
Sorry for the blurry-ish photos
Edit
Less blurry photos have been added, with most of the old ones removed

The Dunkis had two ideas to put into this gun:
- A bolt catch, to keep the charging handle backwards, and a seperate trigger / button to release it.
- A magazine release trigger / button close to the trigger.

The first idea is successfully incorporated into the gun. It's a small button you push forwards to release the charging handle.
The second idea is a bit different. The trigger for the magazine release is behind the handle, and you pull it with your thumb to release the magazine.
