Blemishes may include one or some of the following:

    1. BEAUTIFUL! THANK YOU!

      I ordered a blemished rose gold BCG from Cryptic and couldn't be happier. The blem is a small imperfection in the coating on the "inside" side of the bcg and barely noticeable at all. Can't be seen when in the rifle anyway. Slick as can be and just looks amazing. Big should out to Karen @ Cryptic for all of her help. Thanks again! on 8th Jun 2017

    2. BEST BCG'S IN MY OPINION..

      This will be my fourth BCG group I have gotten from Cryptic 2 are 5.56 one black mystic, one bronze..same with 2, 7.62 black and bronze. All of them I got were blemish but one it was bronze 5.56, they are all great, the blemish you can hardly tell,talking microscope shit. If I did it over again I don't think it is worth the extra money for the black, and if your camouflage your stuff the bronze fits in very well. OVER ALL GREAT PRODUCT'S. PEOPLE ARE VERY HELPFUL AND THOSE THINGS ARE LIKE BUTTER. Only have a little over 1K rounds on 5.56 but they clean and operated like BUTTER. NOW if they will only give me some promo code for the next 4 I buy. on 29th May 2017

    3. Awesome

      Although listed as blemished, it is like brand new. on 18th May 2017

    4. Very nice

      Can not find the blemish and I can't imagine a higher quality bcg on 16th May 2017

    5. Perfect!

      Some 3k rounds later still minimal cleaning no loss of finish and now my personal favorite BCG.
      Cant go wrong will order again.

    6. Great BCG

      Never found the blemish. Quality control must be done with magnifying glasses. Thank you for the candy!!! on 25th Apr 2017

    7. Absolutely awesome

      Great product. No identifiable blemishes that I could find after thorough inspection. Shoots great and cleans up even better. Nothing sticks to this BCG. Plus, the package comes with free candy! My wife enjoyed the sugar high. on 30th Mar 2017

    8. Can't tell it's perfect!!!!

      Order a blemished copper bolt. Can't tell it's perfect. Works and looks flawless. on 14th Mar 2017

    9. Couldn't find the blem

      I'm not sure what about it makes it blemished, but I couldn't find it. BCG ran smooth and didn't have any hiccups in 200-300 rounds. I got mystic black and it's just as nice looking and smooth as the one I have and paid full price for. on 6th Mar 2017

    10. Second Bolt carrier group

      My first order was a Mystic Gold .556 and cleaned it up like new in no time. my parkerized for my Blackout took forever. I received my Mystic Bronze BLEMISHED super fast. After 750 rounds it cleaned up just as well. Now I have a spare bolt carrier group. If there is another build, a Mystic Black will be used.
      Thank You
