    Reviewer: Anonymous Person  
    I finally was able to test out my upper. I put approximately 250 rounds of 110gr supersonic rounds and all the rounds cycled flawlessly.  I highly recommend this upper, it'll except  subsonic and supersonic rounds.

    Reviewer: Gregory V. from Twinsburg, OH United States  
    I bought one of these uppers because I always wanted to see what the 300 blackout was like but didn't want to spend a lot of money.  Well, to make a long story short, I am impressed.  I have over 600 rounds through it, both subsonic and supersonic, without a FTE or FTF.  Accuracy is way above what I expected for an upper at this price.  I have talked two friends into buying this upper and have heard no complaints from them.
