Blemishes may include one or some of the following:

  • Poor logo marking, or missing logo.

    1. Fantastic

      Incredible BCG. Love the polish. Rock solid. on 18th Feb 2021

    2. Blemish? What blemish?

      Looked it over a lot, can't find a blemish. One of the few products that actually does improve AR function (and cleaning is ridiculously easy). on 29th Jan 2021

    3. Worth every cent

      I picked up a blemished gold and bronze BCG. They both look absolutely incredible.

    4. My new favorite BCG!!!

      I just purchased a BLEM cryptic bronze 556 BCG. I figured i would be able to see the BLEM but once it arrived, I honestly couldn't find anything! After doing some research on the hardness of the coatings, I can't wait to see how well this BCG performs and how well the wear areas hold up. I have many BCG's and this is "BY FAR" the best made one I have. From my own experience, you never want to skimp on the barrel and BCG when building an AR platform rifle. This will not be my last Cryptic BCG and will not have any issue paying the extra money for this quality again! on 12th Dec 2020

    5. Flawless

      I searched this whole bcg for a flaw, couldn't find a single blemish. The finish is exceptional, like a mirror. Still working on my build so I haven't had a chance to actually test it. But it looks amazing in my spikes tactical billet upper. on 8th Dec 2020

    6. Blemish?? I found NONE

      Outstanding quality like always from Cryptic. I ordered the blemish, but honestly could not find a single flaw that made it qualify as a blemish. Extremely happy and satisfied with the BCG. on 8th Dec 2020

    7. Blemished 5.56 mystic gold bcg not blemished at all!

      I purchased a blemished bcg to save a couple of bucks and there is nothing blemished about it. The finish on the bcg is flawless. I purchased the mystic gold color and the pics don't do it justice. I'm using this for a skeletonized build. I have yet to fire it, but time will tell how it functions. The order was processed extremely fast and the bcg was mailed just as quickly. Received it in a matter of days. I highly recommend this company. Also, they there in a free sticker, cleaning cloth, and the bc was wrapped extremely well and secure for delivery. on 7th Dec 2020

    8. Great buy!!!So shiny!

      Ordered my blemished coated bcg and i cant find the blemish. Order was shipped right away and when received the product was packaged very well with a few goodies inside. Went in my build with no issue and looks amazing on my rifle. If ur on the fence just do it, you'll be glad u did! on 7th Dec 2020

    10. Mystic Gold BCG 5.56 (Blem)

      I was blown away at the finish of this bolt carrier group. I haven't fired it yet so I will do a follow up review after I complete a test fire. Shipping was fast and packaging was satisfactory. Very happy with my purchase and I intend to purchase another BCG in the near future. on 1st Dec 2020
