Does anyone have any experience with Toolcraft BCGs offered by cryptic coatings? I've only heard good things about Toolcraft, but I haven't seen ANYTHING about CC. I came across one review on google, but it's written by someone who is very opinionated and ignorant. I'm only interested in the nickel boron bcd, but the copper-colored one looks interesting. Anyone own one of these?

I'll be buying a BCG for my build this upcoming week......I'll include the link to CC's storefront below.

I just recieved mine last week and I have to say I was thoroughly impressed, and im not much for wonder products. I had a lengthy email conversation with the owner a decided to give one a shot. Its slick as snot and easy to clean, and the coatting is very hard. I went with mystic black. It also holds fire clean pretty well

They sure are pretty.  I have been trying to justify a reason to buy one

Thanks for the feedback! Excited to see I'm not the only person who has discovered them. I'm not into the flashy-colored ones, and I'm not too concerned with how "slick" their magical coating is. I'm just wanting a reliable bolt with a solid company that stands behind their products. And I don't like buying things from California, but that's just a personal preference. lol. I think I'm gonna try one out...

I also asked about possible embrittlement issues, there answer

"We don’t use any chemicals with any level of hydrogen atoms. That’s import as hydrogen embrittlement is the issue with many heat treatment and chemical processes. A simple answer to your question is just "no"."

Neat concept. I am curious as to:

-Thickness of coating?
-Were the BCG's made with this tolerance in mind, specifically for CC's coating?
-Would love to see a cam-pin with some rounds on it to assess "wear". I know my QPQ cam-pins wore exceptionally slowly. The CC coating looks to do the same based on that one link.

No thanks. I don't fall for the whole marketing hype of coating BCGs in fancy coatings. My standard phosphate BCM works just fine.

That's not meant to compete with BCM. It's a "game gun" BCG meant for tuning in conjunction with a super light buffer and adj. gas block. It also looks killer well made! Your BCM would suck for that application, and it would suck for what you use your BCM BCG for. Total apples/oranges. Like trying to race a Dodge 2500 at the Indy500, or mudride an indy car.

I installed one--a keyed carrier--in my Mega-based 308 and have a full BCG incoming for a AR15 build, both mystic black.  I will get out of the way the part that they aren't cheap, and that a lubed, standard BCG will function just fine for less.  

But I like trying new things, and I'm OK spending the extra money for that end.  I have BCGs in phosphorous, chrome, NiB, and now Mystic Black...  While none of my rifles are safe queens, I'm not likely to push anyone of them to an extreme that will test just how good/ better/ meh the coated BCGs are.

That said... Quality seems quite good.  The finish is very smooth, and charging the rifle was noticeably smoother with the CC carrier vs that original phosphorous one.  Cleanup is quicker, though I'm waiting for the 5.56 bcg for a high round test run.  That is a tougher proposition with the 308.  

And to top it all off, I have had helpful and informative email exchanges with Gary, CC's POC, and received a handwritten thank you card from them.

smoother recoil, faster cyclic rate, reduced carbon fouling.



I had no idea a coating could do so much

The BC has only four relatively small bearing surfaces, rails under the key, and the bottom corner of the front half. It's doubtful you could feel a difference, and even so, after 200 rounds when the surfaces burnished you could not.

 



Your other logic is sound though, and the coating do look neat.




However, they do not offer ME any advantage over cosmetics so I will just look at pics of them in other's rifles

Understood! I have a few hobbies so spending money on how a gun looks is usually not high on my list. I do think the copper colored one is pretty neat looking though!

One of my pet peeves is bolt carrier manufacturers advertising "Grade 8 Socket Head Cap Screws"!

If they are indeed using them they are in all probability cheap "off shore" manufactured. Since around 1991 the standard for U.S. manufactured Socket Head Cap Screws is ASTM A574 which is STRONGER than the old Grade 8 standard.

I'm not sure where to find that specific information without sending a few emails, but it's a possibility the material is cited here in the USA. Toolcraft has filled a few DoD contracts for BCGs. And while I am in the military, I'm not 100% sure how all that works. I'm assuming all the material is cited here to fulfill military contracts....

That's a good question. We sincerely believe we are using the highest quality US made bolt available. We will do our best to follow our supplier back to the source and get to everyone on this.

I sent an e-mail to Cryptic on Sunday afternoon asking some questions on the bolt carrier. I had a reply in 20 minutes with attached photos. Most impressed with that turnaround on a Sunday.

I bought a Tool Craft bolt from Cryptic Coatings to complete a BCG I had laying around.  I was very surprised at the quality as it is VERY nice.  (noob analysis)  It is just a standard bolt with no special finishes.  Their specifications are solid and under a magnifying glass it shows.  I will say, it made enough impression on me that I will be trying one of their complete BCG's if I need a replacement or start a new build...

I'm running one in my 14.5" .308 with a can. It cleans up with a paper towel and after a couple thousand rounds it looks like new.

It is honestly the best BCG I own as far as fit and finish go.

Well that IS a little more tempting at that price. I tried ordering a .223/5/56 in the Mystic Bronze finish and the price was $235. Maybe I cab pick one up on the EE for less than $200... It would look sweet in my new MEGA build and the current NB BCG could go in one of my back up Spikes builds.

Who uses those?  Even BCM uses the Grade 8 (albeit domestic)....I"m not saying it with a "tone" either.  I'm genuinely curious.

Do a search among reputable U.S. suppliers for socket head cap screws and see if ANY of them list "Grade 8". I bet you only find ASTM A574.

I guess what I'm getting at is we are so ingrained that "Grade 8" is the end all, be all that the carrier retailers state GRADE 8 because they think we will buy Grade 8 but we wouldn't if they listed ASTM A574 even though ASTM A574 is STRONGER!

Toolcraft has a DOD replacement contract.  I highly doubt they're using cheap materials.
