    Ordered this complete upper as an x-mas present to myself 12/15/15 from impact guns. Arrived at my door step within 5 days earlier than expected! Took it apart cleaned and lubricated everything, dropped on an extra bushmaster lower i had (carbon)!Took to range next day and put 160 rounds thru it, flawless, great groupings at 50 to 75 yards. cant wait to fire it again, will recommend this upper. awesome!!!

    Bushmaster A3 Upper

    Purchased this to use for my lower AR build. Fit perfectly out of the box. I put 100 rounds through it and the accuracy out of the box was better than expected. I did not need to make any sight adjustments. I would definitely recommend this upper!

    Easy Drop-In, Nice "piece."

    Posted by Big Bore on Jun 24th 2014

    Manufactured my own "lower" and dropped in this A3 "upper." A "Piece of Cake!" Easier than I expected and smooth as silk fit. I couldn't be happier as this is my first attempt at making my own AR-15. I own a couple of others (Colt SP-1's) and this is every bit as nice as the Colt, so far. I'm going to make another, and I'll use the Bushmaster A3 Upper again.

    Great setup and very lite.

    Posted by don G. on Sep 30th 2013

    I put this upper on my Bushmaster lower that had been highly modified for target matches. I didn't want to wear that expensive upper out. This upper puts shots into the 10 and X ring 90% of the time at 200 yards. I would actually give it a 4.5 star rating if I could due to the excessive movement in the rear site on the carry handle. But Hey this is a service rifle not a super match. I'm going to remove the carry handle and mount a better site assembly for practice. But if I had to go to battle I'd go back to the carry handle.
