Curious if anyone has one.  Saw these on Atlantic's website.  Wanted a 5.56 AK.  Are the receivers stamped?  Got a bunch of Zentico furniture I want to utilize and I know they don't really work easily on Milled receivers.

Curious overall in terms of reliability and such.  Also are the muzzle threads concentric?  Like to use a Sandman S.

Thanks

I believe they just released those today on Atlantic.

Placed my order on Friday.  Gonna give it a shot. Really excited to get a 5.56 AK.  Hope to get lucky and get some concentric threads so I can run a suppressor.

I have a new WBP Jack in 5.56 and I've had it to the range and I am very impressed with it. I only shot at 50 yards because I was going to sight it in, but the sights are dead on right from the factory and aligned perfectly. I tried Circle 10 20 round mags and WBP 10 round mags and they both fit very well. The rifle is very easy and comfortable to shoot, although slightly over gassed as it throws cases 25 feet away. I tried 3 different types of ammo all 55gr, PMC, Igman, and Federal and the rifle likes the PMC the best as it did 1.5" group at 50 yards with just the iron sights. I'm waiting on a RS regulate side mount to arrive so I can mount an Holosun 503c on this rifle. I own 3 other AK rifles and this Jack is the nicest fit and finished of them all. I bought it from Atlantic firearms and they did an excellent job getting it to me rather quickly and in excellent shape. My rifle came with a superb trigger right out of the box at just under 3 lbs, hopefully they all do.

Sir, any idea when you'll be getting more of these in stock?

Thank you for the response.  Looking forward to picking one of these up.
