    this is the perfect length barrel upper for 300BO. The upper runs like a champ 115,120 and 200 grain bullets @ 100 yards. This is perfect for home defense or truck gun. I'm planning on getting the 16 inch Aero next for hunting past 100 yards.

    This was delivered in a timely fashion and nicely packaged in Aero Precision original box. I have yet to build anything else around this yet and certainly haven't put any rounds through it but I'm very happy with the initial observed quality. Aero holds up to their reputation for best quality on a budget and Wing tactical made for quick and easy transaction. Happy with this find on their website. Only 4 star review since I have yet to put any rounds through it.
