7.62x39 the easy way - Maxim Defense Industries PDX U.R.G. Mil-Spec Upper Receiver

I wanted to add a 7.62x39 to my AR lineup and I went through my parts bin to see what I had and started thinking about what I would need to buy or change. A few of my AR friends were pretty discouraging about how they had tried it and had very unreliable results for various reasons. Ultimately I decided in this case it would be better for me to buy than to build. Boy was I right! I have dropped this on a few different lowers to make sure it's not a fluke. This upper will chew through anything I feed it. Brass case ammo, steel case ammo, good ammo, junk ammo, new ammo, old ammo, you name it. The ONLY think this upper is picky about is magazines. For ME on several different lowers. Duramags worked flawless. I'm not going down the list of what didn't work well it's long. Duramags and this upper in every lower I tried ran everything. 7.62x39 is cheap. Yes the upper is expensive - have you checked out the price of 5.56 or 300 Blackout lately? If you need to train or want to shoot this is money well spent. Plus sometimes just having something different is cool!

NOTE: I bought the MILSPEC version. You will need to consider your buffer weight depending on the caliber you purchase.
