In over 400 rounds, with cheap Winchester white box from Walmart and my own hand loads using both round nose and semi-wadcutter from Berry's, there have been no failures.
The fully loaded factory magazines feed from top to bottom with no issues. A very fun gun to shoot with almost no recoil due it's very heavy weight. Built like a tank with heavy steel throughout and does not get too hot, easy to handle even after several 30rd mag dumps, unlike my AK.
The black finish is a bit fragile and in less than a month I have rust showing on the parts that have come into contact with my skin, including the magazines, so be vigilant with the finish.
Both the muzzle brake and the forearm retaining ring work loose periodically, recommend a non-permanent thread locker on both. The picture is inaccurate as stated and does not show the quad-rail forearm or the adjustable stock.
Using an inexpensive reflex sight and foregrip on this gun makes it loads of fun. Unlike the one in the picture the stock does not remove cleanly with one screw, it is one screw, but leaves a protrusion reminiscent of what you might see on a 5.56 pistol.
Did not like or try the iron sights.
First gun I've bought online but a very easy process thanks to Hinterland and my FFL.
5 stars for both Hinterland and Masterpiece Arms.

I have owned this weapon for two years or so. When I first received it I took it out and fired one shot. That was the last shot it fired. Turns out the factory assembler put the 9mm firing pin in. MPA immediately sent me the entire bolt assembly.
After that was fixed I took it out again and started testing. The magazine that came with the weapon would absolutely not feed reliably all the way to the top. I removed the spring only to find it was the same length as the magazine. Instead of making a stink, for I'm sure someone else would do so if it was a wide-spread problem, I ordered a replacement spring from U.S. Machine Gun.
That spring was twice as long as the mag and since then the weapon has never missed a beat. Now, how does it shoot? AWESOME! I LOVE this thing! I have destroyed a target's center from 50 yards. I'm pretty sure it could do the same at 100 yards.
I put a red dot scope on it and have never looked back. It will shoot as fast as I can pull the trigger, spraying a LOT of lead downrange. After all, we are talking about .45 ACP rounds! This is a very fun rifle to shoot and accessorize. You won't be sorry for purchasing it at the price most dealers ask for it, especially Hinterland.
