Hi everyone, I am trying to gauge interest in 300 AAC Blackout Uppers. We are starting a venture to produce the highest quality uppers and I am trying to see if the caliber is what you are looking for. If so, what barrel length would you be most interested in, and what gas length would you want? All barrels would be stainless. Also, since they would be uppers and fit your standard AR, would you want a bolt carrier group and a charging handle? I don't have any specs yet, but as I iron out the details, I will try to appraise you of the details. Thanks for the info.
