Hey guys. I'm getting ready to submit my Form 1 sometime next week to SBR my factory BCM lower. I'm having a tough time making a decision on an upper for my rifle. I want a factory built upper from a reputable company that I shouldn't have any issues with. As far as length goes, I'm pretty set on a 10.5 at this point. Being that I'm taking the time to build an SBR, I want to go as reasonably short as reliability will allow me and that seems to be the point. In a perfect world, I'd like to be under or around $1000, but would spend more to get what I want. Ideally I would like a 10.5" barrel with a 9" or similar low profile rail (VTAC, MI Gen 2, etc). The options above are the ones I'm looking at right now, but there may have been more I have missed. I'm looking for feedback and personal expierence as well as any suggestions or comments. I feel like my biggest issue will be finding anything in stock right now. Thanks
