I need an AR upper. I know I want a 16" flat-top with a midlength handguard and a fixed front sight, and I want something that's not going to puke if I stuff a case of ammo through it in one weekend. But other than that, I don't have many hard-and-fast specs in mind.
I'd love me a DD or BCM, but I'm torn between that and screwing one together using good parts on my own. Thoughts? Suggestions? Sources for good deals?
Also, I'm debating a .300BLK or 6.8SPC carbine barrel assembly (or barrel & BCG in the case of the latter) for my MGA switch-barrel upper, but that could be another thread.
