    Bought two of these!!

    Bought two of these to tods into a couple Diamondback upper receivers. All I can say is what an improvement! Let me also state...there are two different machining marks on these. One is blank, one says made in USA. Do not be fooled, both are very high quality but I do like the made in USA markings. Go trump and lets stand together to keep this 2nd amendment alive and safe from liberals. Orlando recently had a shooting and that was terrorism, not the AR15! Thanks RTB!!

    First time using this!

    I haven't shot the rifle yet. The BCG fits well, clean finish, overall fit and finish is very nice.

    Sweet BCG

    Not only is this another high quality product from spikes It's got some style. It's a subtle spider on the blot when the dust cover is down but when your building your gun and want people to know your using quality the see it and they know your using great products.
