Grid defense upper - Grid Defense 7.62x39 Upper Receiver

I came across this upper on optics planet while looking for some other build parts. It had a few different color and length options to choose from. I'm a budget guy, and the price point was in my range. On top that I had a coupon, so overall I got a heck of a deal on it. Shipping time was reasonable, the upper showed up in perfect condition and after quick assembly it was time for a test fire. So far I'm very impressed with the overall function and cost of the upper. I'll be buying another soon for my next build. 5 Stars all the way.
