Thomas white - Radical Firearms 16 in. 300 AAC Blackout Upper Assembly

I received the upper receiver and really enjoy it, and took it out to sight in my scope and i used 150 grain rounds and it shot like a dream, so i will be recommending this product to any one that is thinking about converting there 5.56 or 223 to a 300 blk put then optics is the best place yo get it.
