I have built a few lowers, but this was my first complete upper kit. Went together very nicely. Assembled the unit, and had it looked over by an ex military armorer, now professional builder, who said overall an excellent kit (like a previous review, the rail on the guard is a slight height difference from the upper receiver - no big deal) and a great value. Shot beautifully. I will definitely be a repeat buyer.

I ordered this, a complete lower build kit, and a bcg on the 12-16-17, I figured shipping would take a few weeks. I was surprised when I got it just a few days after christmas. I was even more suprised at the quality. This was my first AR build and won't be my last. Everything went together flawlessly. All of the parts were well packaged and grouped together for easy assembly. To be honest, when I ordered this upper and all of the rest of the parts, I wasn't expecting much because of the low price, but the quality was way beyond my expectations. The rifle functioned and fired flawlessly. The only somewhat negative thing of this order (if i had to give one) is the berral I got with my order was a 1:8. That was not a deal breaker for me. Not even worth calling and complaining about. I give these guys 5 stars.

Bought this FFAR12-O to try it out. The price is super low so wasn't really expecting much out of it but it's actually not a bad product. I would have given it 5 stars but the rails from the guard are just about a hair above the rail on the upper. Not a big deal but also not perfect. Can't complain much since it wasn't expensive.
