    I purchased this lower through a major retailer for a build. After receiving it and putting the rifle togerher, this lower far surpassed my expectations. It has tight tolerances and fitment, and the quality is outstanding. I bought 7 more and it has now become my preferred lower over my previous well known brand choice. You will be very happy with the quality and performance and reliability.

    I purchased a complete Matrix Aerospace AR-15 rifle from a local gun store.
    The very first thing I did was to check the fit of the upper and lower receivers. They were tight as a drum, and I bought the rifle.
    I later tore down the rifle and built a M4 with the best parts I could get. I had 3 other AR platform rifles, including a Rock River Arms Carbine. The Matrix Receiver set is still the very best I have, or could ask for. The finish is flawless, as is the rest of this set.
    Fantastic Work Guys! You can’t go wrong with Matrix Arms!
