    I purchased this upper, it arrived Tuesday, I took it out yesterday. Processing and shipping was very prompt.

    Out of the box everything was machined nice, the finish was nice, I didn’t notice any scratches or dings on it. It was definitely inspected twice before going in a box. Everything looks well made, and fits together well. I would arguably put B. King Firearms up there with other tier 1 manufacturers.

    I did swap the bird cage for a Surefire War Comp. I ran Troy iron sights, a Sig ambi charging handle, and I have a BCG from another reputable online retailer I had ordered before I discovered B. King Firearms. For ammo I ran a mix of some Gemtech sub sonics, Winchester white box FMJ and JHP, and AAC 110 VMAX.

    So I oiled the top of the charging handle and the bolt and off I went. The upper ran very well, I had no hiccups, It’s a really fun gun to shoot, it’s very accurate. I only took it back to about 50, and it was windy out. But I was very impressed with how accurate Blackout was out of an 8″ barrel. I would say this is the answer to the PDW question, and it definitely out performs other options out of a short barrel such as 5.56, or a Draco.

    B. King Firearms is my new favorite online firearms retailer after this experience.
