Coated Bolt Carrier Group - BLEMISHED
Take advantage of our attention to detail.... 15% off in fact. These blemished bolt carrier groups didn't meet our expectation therefore we are passing some savings on to our customers.

Blemishes may include one or some of the following:
- Poor logo marking, or missing logo.
- Imperfect polishing, contained mostly on the inside of the carrier, causing a non mirror-like finish.

Amazing BCG
This company does not play!!! These things are amazing. Besides looking GREAT ,they are so slippery I can barely hold on to it. This is the only BCG company I’ll EVER spend money on, hands down. I will be buying the black one for my Daniel Defense. KEEP UP THE AMAZING WORK! Rudy on 13th Jun 2018

quit reading reviews and just buy it
Outstanding fit and finish but more importantly FUNCTION! Installed Cryptic silver BCG in a rifle which was acting undergassed with a parkerized BCG. Shortstroking immedetiately went away and bolt locked back on an empty magazine every time. Casings eject to 3:30-4:00 and would all land in a five gallon bucket. clean up is a snap as carbon just does not stick to this coating. Could not find any blem (maybe a few tool marks on the i.d. in the rear of bcg that effects nothing). shipping was very fast and packaging was great. Cryptic coatings just added another very satisfied customer

Can’t tell it’s blemished
As all the other reviews stated, I too took a chance on a blemished BCG in mystic black for my aero 308 build. Arrived quick and packaged perfectly. Broke the bolt down and still could not find the blemish. Worth every penny, 100 rounds through it this past weekend and wiped the bolt clean no problem. Looking forward to doing business again in the near future! Dan from NY on 30th May 2018

High Quality and Affordable
The bolt carrier had some scuffs on the nitriding but that's to be expected with a blemished model. The bolt itself looks flawless and headspaced without an issue. You get a high pressure tested and MPI bolt at a great price. Joe on 4th May 2018

Exceptional BCG
I received this request long before I got to try bolt carrier and as it turns out like everyone else said. It worked perfectly it looks cool cleaning it was a cinch. I bought the blemished and could not find any flaws....Good Job CRYPTIC COATINGS......Paul Unknown on 17th Apr 2018

Great Overall Producs
I bought 4 blemished and 1 new over the years for my rifles. I cannot tell a difference between them. All of them have functioned flawlessly, and I haven’t broken anything after about 3k rounds. Most of these were with a suppressor as well.
Cleaning is a breeze. You can literally just wipe it down and it’s good as new. I haven’t experienced carbon buildup that I had to scrape from the bolt other than wiping it.
They sure are pricey, but well worth it if you are lazy and want a good quality product. Unknown on 26th Mar 2018 -
Wow!
After reading the reviews I ordered a blemished BCG in Mystic Silver and all I can say is wow! I don't know where the blemish is, but there must be one somewhere. I used this in a 300 Blackout build with a skeletonized upper and the silver BCG, along with a stainless steel barrel, really makes this pistol stand out. The BCG preformed flawlessly from the first round and I plan on ordering a gold one for my next project. You will not be disappointed! Darin on 22nd Mar 2018

Blemished
I honestly did not see any blemishes. I shot roughly 150 rounds through it, took it apart to clean it, and found a spot that the carbon didn't immediately wipe clean from. Im assuming that's the blemished spot, it's tiny, and i don't care. These guys build awesome stuff. Grant on 20th Mar 2018
