Expert Review Suberb quality and function - Jacob Grey Firearms Ultralight 7.62x39mm Complete Upper Assembly

I am a huge fan of the 7.62x39 caliber, but am not a fan of AK rifles. I've tried several times to build a 7.62x39 AR platform firearm, but have always had issues with feeding, cycling, etc. I had just chalked it up to the fact that 7.62x39 wasn't designed for the AR platform. I decided to give it one more change with this Jacob Grey Ultralight upper, and I was blown away. This upper functions flawlessly right out of the box with numerous combinations of mags and ammo. I've never had this happen with any of my other "AK-15" builds. Not only did this thing run great, the build quality is exceptional and the attention to detail in all aspects of the gun make it one you'll reach for everytime you head to the range. I highly reccomend this upper and I plan to buy others from Jacob Grey and OpticsPlanet again soon!
