this was the last part I needed to finish my Aero 308 build. toolcraft makes really nice BCG and this is one of three of their 308 BCG that I have bought. fit and finish is always excellent on their BCG and I have several of their BCG in my AR15's too. and as always shipping was very fast and packaging was great.



Tom's has great price on a quality product and really enjoyed the free shipping that does take forever to receive
