    1. Quality

      Have not fired using this Bcg yet. It came quick and the quality is next to none. on 17th Sep 2018

    2. Best BCG Ever

      Amazing BCG. Works flawlessly and super easy to clean. Would highly recommend the Bronze BCG. on 13th Sep 2018

    3. Well worth the money.

      If you are shooting suppressed or simply don't clean your gun to often and let the powder build up, this is the bcg for you. It is slick and super easy to clean. Its as easy as just wiping off no matter if it seen 10 rounds or 1000 rounds. I have the bronze as well as the mystic black both are awesome. on 11th Sep 2018

    4. flawless

      awesome bcg PSA upper 7.5 inch barrel with binary trigger 100 rounds ran perfect an still clean when it was all over on 3rd Sep 2018

      Absolutely perfect coating and seems very durable on 1st Sep 2018

    6. Gold bcg

      The mystic gold bcg is beautiful and cleans up excellent just wipe it down and your done. I would recommend this bcg to anyone smooth I get looks everytime I bring my ar to the range. on 30th Aug 2018

    8. Mystic Black

      This BCG is a thing of beauty. I haven't had a chance to test it yet as my build is still in progress. on 8th Aug 2018

    9. So far so good

      So far so good. The coating is flawless, looks awesome and its nice and slick. Gas key has good staking, and the bolt matched up perfect with my faxon barrel. I ran about 60 rounds through it so far and it seems to work good. on 3rd Aug 2018

    10. Well Worth It

      I waited to write this until I had the chance to run it through a few hundred rounds. This is slickest, easiest to clean BCG I have ever had. You might be deterred by the price but the quality and uniformity of the coating are exceptional. This blows the nickel boron and nitride finishes out of the water. If I build another rifle this will be the BCG I purchase, may replace the others with this. on 11th Jul 2018
