    1. Absolutely Brilliant

      Ive owned a lot of crap BCG’s so i’d like to think I can spot quality and point out any failures or shortcomings in a good one. Let me just this has exceeded my every expectation. The Mystic Silver BCG not only looks absolutely stunning in the rifle but the lubricity and overall smooth feel while charging just pays for itself. Even easier than a Nickel Boron BCG. I have to say i’m impressed not only for the performance but also the cleaning. Gone are the days of using 4-5 qtips plus rags plus cleaner etc just to get a shine, this thing wipes off! Little bit of cleaner and a shop towel and youre done, fantastic. Absolutely worth every penny of purchase price. on 22nd Jun 2020

    2. Hand Picked Blemished

      These BCGs are in very good tolerances despite the blemished designation. The company does a very good job of providing you with a specific blemished model such as one with no logo. The blemished on the BCGs are so minuit themselves that they are almost impossible to detect. Great product and Great service. on 8th Jun 2020

    3. Bolt Carrier Group in Gold

      I’m very please with this BCG. It’s aesthetics and construction are a thousand times better than BCG’s by other brands I’ve tried. It performs flawlessly and is so simple to clean. I just wipe away the carbon and I’m ready for more action...110% A+++++ on 21st May 2020

    4. Coated Bolt

      Love these bolts, easy clean up no scrubbing or picking required to remove carbon deposits, wish I discovered them a long time ago. Have 20 plus years of intensive shooting experience, these bolts minimize my time doing weapons recovery and maintenance after a day on the range. Only gave it 4 stars because of the price, but you get what you pay for. on 24th Apr 2020

    5. Freaking awesome!

      Hate cleaning your bcg? Hate carbon and fouling build-up? Want the ABSOLUTE slickest, smoothest, easy to wipe down bcg there is? This is it. Period. This thing feels like wet glass when it's dry and even better when oiled. Think polished blued covered in motor oil sliding on fresh ice just done by a Zamboni. This thing laughs at teflon coated anything. I have those too, this is better. If nickel teflon or nickel boron is Picard with the USS Enterprise's warp drive, this bcg is Han Solo in the Millennium Falcon doing the Kessel Run in less than 12 Parsecs to steal your girl.

      This is the second one of these I've bought for two rifle builds I've done. Both in the mystic black. The first was brand new, and this second one was a blemished version I could really say 'blemished' because I can't seem to find any defects, and as a former Marine and current owner of several AR's, I'd like to think I know what matters and what to look for. If you're on the fence about it, just do it. I hated scrubbing and scraping the bcg in the service. This thing makes it so easy it's almost fun.

      While these are on the pricey side, they are totally worth it. Save another hundo or two and get this one. I'm a Firefighter/EMT so that's what I did and I'm so happy with this in my guns. I recommend these to everyone looking to upgrade your bcg or get the sweetest one that'll take you less time to clean than you've spent reading this review. Seriously, it just. Wipes. Off.

    6. Just plain amazing!!!

      These blemished BCGs still exceed the best of what you'd get elsewhere. You will not be able to find the blemish. I have looked at mine forever and still can't find it. That mystic bronze pops too and is super smooth. Cryptic is my new go to.

      FYI delivery was very quick as well.

    7. Gorgeous...

      The guys at Cryptic must have the most insanely high standards when it comes to their stuff. The "blemished" (I can't find a thing wrong at all) BCG is pristine. Not only that but the coating is GORGEOUS. It's a shame nobody will ever see it. I'll never use another BCG from anyone else. on 9th Mar 2020

    8. Slick as snell shit!!!

      Have two bcd from Cryptic. I run suppressors with everything and it is the easiest to clean! No solutions are required but just a few wipes. U won’t regret purchase! on 26th Feb 2020

    9. Its all good...if you can afford it

      i have had dozens of bolts from various companies and few match the finish quality of these products. With these bolts at the higher end of the price spectrum i expect exceptional costumer service and this company seems to on target.
      overall, i feel the AR bolt market is very competitive if not even saturated but from what i can tell this company is making quality "high-end" parts that are great if you can afford them and if the company can withstand the competition.

      from what i can tell your getting a great product, but i expect that at this price point.
