    This upper is awesome! I also have a 223 upper. I was very impressed with the fit, finish, and function so I decided to give this one a try! Took it to the range today and was impressed with my groups! I would recommend to anyone looking for an upper in this caliber! It shot everything I fed it, steel case & brass! No failures to feed or eject!

    The handgaurd on this assembly looks and feels great, and you cant beat the price. However, I noticed that the keymod cutouts themselves arent beveled on the inside, which is necessary to accept any after market attachments. Which is kind of a critical flaw in my opinion. Unless just the handgaurd I received missed a step in the machining process. That would be something to consider to any potential buyers.

    I bought this upper to use for the new Indiana law to use rifle calibers on private land to deer hunt. I wanted an effective, but affordable to shoot caliber, and chose the 7.62×39.
    After initial zeroing in, I consistently achieved 1/2″ groups at 100 yds with this bbl, and have shot brass and steel case through it with never a malfunction.
    This upper fits my Magtech lower perfectly. The quality and craftsmanship of this bbl is apparent as soon as you pick it up.
    And, to increase my pleasure, I bagged a very nice 8 pt buck with it at approximately 100 yds.
    I highly recommend this to anyone looking for the AK caliber on a AR platform.
