Oleg Volk produced a Youtube video with Fostech’s Origin 12, 12 gauge shotgun, shooting through a suppressor, and a drum. It was all over the internet in days and we got a chance to check out the shotgun while at SHOT. Fostech is a family run business that takes its name from the founders last name, Foster. They make a number of AR related parts in addition to the Origin 12 shotgun, such as bumpfire stocks, triggers, and complete AR lowers. However their shotgun has been around for a couple of years and is available in either NFA Short Barrel Shotgun or legal barrel lengths. Essentially it is an extremely modified Kalashnikov action with a number of changes.
Folding polymer dust cover, charging handle is on the left side as well as being much more forward on the gun, unlike a standard AK. The non-recripricating handle is actually just above the handguards and not on the receiver.
Magazine release inside the trigger guard, in addition to a receiver mounted bolt release within reach of the trigger finger
Magazine insertion housing that allows a shooter to insert a magazine in directly, instead of rocking it into place, AK style.
Shooter adjustable gas tube, this is done by unscrewing a knob above the muzzle out to let more gas flow back, in addition it is shaped in a way that you can insert a 12 gauge shell into it, to adjust it when it gets really dirty, or too hot
The bolt has been skeletonized to reduce weight
The receiver cover hinges at the rear, just above the stock, similar to a Krink type that instead hinges at the front, by the gas tube.
I didn’t ask how much of the shotgun was made in house compared to built on AK parts, but it looks like a good majority of it is, as many of the parts were not standard AK parts. It comes in a variety of magazine capacities from 5 shell box magazines to 30 shell drums. MSRP ranges from $2,600-2,900 depending on configuration.
