This is a Zastava (Yugoslavian) M70AB2 AKM parts kit assembled on a US-made receiver by Citizens Armory in Mexico, Mo. It is the best made AK-style rifle (a tribute to Zastava *and* Darin) in the holdings of Castle Argghhh! in 7.62x39 caliber, and the original Yugo rifles are perceived as being among the best-made and durable of the AKs. They have a more robust stamped receiver and trunnion, as it was intended for use as a grenade-launching rifle, and thus needed the reinforcement. The M70AB2 nomenclature means she's a folding stock version with grenade-launching and night sights. The biggest clue she's a Yugo-built gun is that her foregrips have three cooling slots in them vice the more common two of other AK-style weapons. That, tied with the much larger gas-block that includes a grenade-launching sight is pretty much a clincher.Here she is with her grenade launching sight/gas cutoff flipped up for you to admire. To fire grenades, you removed the muzzle brake and installed a spigot attachment, which is a bit of kit I need to procure. You then flipped the sight up to cut off the gas return so the action wouldn't cycle - this was to maximize and make consistent the launch impulse from the grenade launching blank. The body of the grenade itself was used as the front sight, the flip sight was the rear sight. The Yugos also had "bullet through" grenades, where range was actually set on the grenade, and a standard ball round was fired. That took some getting used to. At least it did for me, when I fired some Belgian "bullet through" grenades during an exchange with the Belgian Army when I was stationed in Germany.
The night sights were originally phosphorus dots, and latterly tritium gas-filled. The parts kits these rifles were built from had the phosphor dots - just one of the reasons they were surplused out I would imagine. The front and rear sights had parts that would be stowed during daylight and they weren't needed. Comes the darkness, then you flipped up a new front sight post and a rear sight notch for night-time fun and adventure.

Lastly - here she is with her stock demurely folded beneath her. The stock will fold over a 30-round magazine, but not, I suspect a 40, and certainly not the drums! She's as accurate as I need her to be - 30 rounds, 30 torso hits at 250 meters, iron sights, when I took her out for a spin two years ago when I invited her to join her fellow bullet launchers in the Arms Room of Argghhh!

Is this your version of "clip vs magazine?"
