    It took me a while to find a quality American made lower, that wasn’t going to tank my budget for my next build. I am very happy with my 8O% lower and I can’t believe how awesome and personal the customer service was! Thank You Matrix!

    Hands down the best machining quality I have ever seen on an 80% lower period. If you’re looking for that precious smooth front magwell you will find it here. The anodized finish did seem a little “dry” at first but applying several heavy applications of CLP seemed to do the trick for me.

    I am happy with the quality and the finished product is great. Wish the price had not shot up

  5. Jason Faus
