As someone who already owns a Kel Tec product (Sub2000 3rd gen) is there any recommendation or tips for someone looking to own a KSG?

I already own a Shotgun already but have been fascinated by the dual barrel/Feed function of the KSG so I already understand it's not the most practical gun.

Be careful, be very very careful!

Two prototypes, a fixed stock and folding. Stamped reciever, gas opporated rotating bolt. The lower is very reminiscent to the Mp9, and other fetures identical to other Interdynamic rifles and later Kellgren designs.

There's next to zero information I've found on this rifle. Despite this, the first picture is seen multible times across Kel-Tec's social media, with no mention to what the Mkt was.

This was the 70s, so I believe it's a fair assumption this was Kellgren's attempt to make a rifle that would become the Swedish Ak5, but I can't confirm that.

Anyone know more?

I was trying to post this to the Forgotten Weapons reddit but it kept being deleted.
