Great quality, great price! May 27, 2017 : Matt L   I bought this to replace a midway competitor barrel due to ultra tight tolerances not allowing the bullet to chamber. All rounds chambered so far but need to get to the range to make sure everything cycles. Will update later... Was this review helpful to you?

Louis September 21, 2016 : Louis C   Worked up a load with the new Sierra 135gr HP using this barrel last week and shooting well under MOA. Love Mas barrels for 300BLK. Was this review helpful to you?

Christopher Kelly April 20, 2016 : Christopher K   I have been building variants of the AR platform for the last 20 years and have to say that these barrels are the finest that I have ever used in my AR builds, I have stuck with MAS Defense for sincefirst finding them three years ago due to the quality and workmanship on their barrels as well as unmatched customer service. I always recommend them as my first choice to anyone who wants to get into the AR platform and get Quality and Accuracy at a good price. Was this review helpful to you?

16" 300 blackout nitride pistol gas February 29, 2016 : Conway S   Great barrel and finish. Extremely happy with my purchase. I was able to reliably cycle supersonic and subsonic ammo when paired with their nickel boron BCG. First purchase from MAS Defense but it will most definitely not be my last!
