In the late 80s or early 90s, Knights had a prototype M16 with a short 10”ish barrel and a short moderator that had an integral flash hider at the muzzle, chopped pistol grip, and iirc a collapsible stock that was shortened.

I used to have photos of it on an old laptop. I believe @coldblue shared photos in the past.

Does this ring a bell for anyone? Any photos?

Thanks, that’s not what I’m thinking of. It’s a late 80s or early 90s prototype. The can was very short and had an integral flash hider at the front.

@Jack_L can you shed some light on this?

Is this what you’re looking for OP?

That’s it! The one I remember had a cut down n-type stock and cut down grip. But that’s it. Thanks!

I built a functional upper for it but have since shelved the project:

I've heard it called the KAC Aircrew Survival Rifle.  Also seen it referred to as the M4A1K.  Story was that it was a carbine built for Heli crews, specifically spec ops birds.  Supposedly around 2 dozen built in the mid 90's.  

Very cool Clone.

The whole concept was wildly ahead of its time. I managed to acquire detailed reference photos from one of the surviving originals and the work done is just... mindblowingly intricate.

I may dust off the project at some point especially now that Form 1 cans are free again, but the stock proved to be a really tough nut to crack and I don't have KAC's engineering budget (or even any skills aside from crude modeling).

Thanks @coldblue! I was hoping you’d be along to post.

Is the barrel ported between front sight and flash hider with an expansion chamber or baffled can? That makes me curious.

The information that I have is that the barrel is not ported, this is instead a booster like the AKS74U.
