Centurion Arms Chrome Sand Cut Bolt Carrier Physicals

[@EastCoastMan603]

Mr. LeClair is a class act. We are very lucky to have a man like him mfg and producing such quality items.

[@LANPOCALYPSE]

I would have to agree. I purchased a C4 rail with the mid length cutout and a couple of the mounting screws had their heads stripped. I emailed him asking what size the screws were and he emailed me back asking for my mailing address. He sent me not one but two whole sets of screws. Have purchased several CMR rails from him since then because not only are his products top notch, his customer service is as well.

[@AKMer47]

Centurion is a very underrated company. Glad to see them getting some love.

[@jackbauer4186]

Everything Centurion makes is absolutely top notch. They make the best combat barrels on the market, IMO. Gassing is perfect and accuracy is phenomenal for a Chromed bore.

I'm happy to say them being sold out isn't my fault on this occasion. They sold out immediately after being announced.

It’s true they were sold out in like 2-3 days after release I wanted to pick up one haha.

They sell out and come back in stock pretty often. Edit: Just sign up for their emails and keep an eye on the page. I think I got in on the second drop thanks to the newsletter. Pretty sure they were up for a number of hours too before selling out

Damn lol I checked too 😆

[@seanwhite304]

I've been raving about Centurion for damn near 15 years . In 2009 I picked up C4 Quad rail and fell in love . I think it was 2013 or 2014 when i picked up an actual upper . Centurion is by far my favorite and Monty is well respected in the community . Centurion CM4 14.5 MIDWEIGHT HF with C4 Chrome M16 BCG and C4 12.5 Quad rail is IMO one of the best Uppers for the money . Can't wait until he makes Chrome Bolt to match but either way his Phosphate bolts are still super solid.. Nice video bro

[@ryand8024]

Lol same bro, I tell people about this company and alot of them never heard about centurion, which is wild because I consider them a top tier. I bought one of their chf barrels with the double chrome bore. Solid af.

[@seanwhite304]

@@ryand8024 Their HF Barrels are freaking awesome because they use a Tapered Bore that aids in pretty insane accuracy. Especially for being C.L..

*Breakaway Torque is the proper term for "reverse torque" in case you were wondering. Thanks for the great video! Carrier looks good.

[@doktorfaustus]

Regarding the vestigial hole through the firing pin retaining pin channel: I'll hazard a guess that Chris Bartocci tried to convince Monty to put the captive retaining pin in these carriers, as I believe those two are also friends and Chris is an advocate for the feature. I suppose it's for the best that it was omitted; imagine how awkward it would be needing to refer to it as the "firing pin retaining pin retaining pin."

[@heatherkelley8115]

I’m thankful Monty put these out. The Knights ones have reached the unobtainium level and this will give others a chance for a solid comparable carrier. I know knights concentrates on government contracts but if I owned a company with this much demand I would definitely find a way to set up more facilities to make more. It is possible to scale and keep quality, and it seems they are just leaving money on the table.

[@ThePatriotParadox]

Hopefully people will realize phosphate chrome lined and chrome with phosphate keys and bolt are the way to go... And companies will flood the market with BCGS like this

Wow I'm impressed with these carriers. I'm even more impressed after your testing and findings. I am for sure picking one up. Thank you for sharing with us sir. It is nice to see someone with your experience and years of knowledge passing that info along to the consumer. It is nice for the manufacturer as well, they can improve any issues or concerns you find. When a company sends products to you for testing, I personally feel pretty good about those companies. Even if you find issues, I think that the company being open and transparent to the community is outstanding. It also lets me know that they care about their products and the end user experience.

[@JeremySankey]

I won't to thank you for your videos. After watching your video on a carrier inspection I was able to figure out why my 300bk and .223 wasn't cycling. (I switch between the two uppers and use the same lower. For now) turned out I had a small pin stuck in the gas key. Once I got it out I had no more issues. Thank you again.

I have 3 BCM bolts ,all 3 have good finish inside and out. Just bought a colt 20 inch upper with a bolt and charging handle. The quality on the colt upper,barrel and bolt are very good. Using a bore scope on the bolt inside the finish is excellent. I am using this colt 20 inch to replace a 1986 Colt HBAR barrel. I wonder If Chad would like to see what the inside of a 13,000 round old HBAR barrel looks like. Make a nice video.

Outstanding

[@evanacey1414]

Hey Chad, I would like to see you gauge out one of Icon Defense’s new BCG’s. They are a new company started by the founders of Mega Arms and Killer Innovations up here in the PNW. There are a couple of features about their carrier that I find compelling. The first is the fact that they are using an integral gas key design, (which we’ve seen before with the old Salient BCG’s), but the second difference I find a little more interesting. They are actually using a modified cam track to increase dwell time by approx 20% and use a proprietary bolt.. If Mike Miller (formerly of Mega Arms) wasn’t one of the guys behind this new brand I feel it would be easier to write them off as another fly-by-night flash in the pan company in the AR space. But with the well deserved respect he has earned in the industry I figured it would probably worth a look and could provide some useful content to the channel. Cheers!

[@Heikin-Ashi-Larry]

Buy one and send it to him

[@evanacey1414]

@@Heikin-Ashi-Larry The entire point of asking him to gauge one out and tell us his thoughts/opinions on them is because we, as consumers of his content, value his opinion and would benefit greatly from having a more thorough and complete understanding of these BCG’s, as it would allow us to make a far more informed decision on whether or not they might actually be worth the $300+ asking price. That said, there are very few people whose name is more widely regarded and respected in the industry (at least from an engineering and design perspective) as Mega Mike’s. After all, this is the guy who, in collaboration with Jim Hodge, invented the wedge lock rail system, and has recently improved on the design with his new “drive lock” rails which are being sold under SOLGW’s “M89” name. So the mere fact that it’s his company that is producing these interesting new BCG’s does carry a considerable amount of weight in my book. So who knows… If Chad is willing to do a video on them I might just take you up on that.

[@ForceRecon112]

I would love to see you do a comparison between a 12.5 centurion arms called hammer, forged chrome lined barrel, and one from Hodge Defense. I know you’ve already done a barrel physical for a Hodge Defense, but I’ve never seen you do one for centurion, and I’m looking at both of them for a potential build

[@terryboone3333]

Ive wondered if Centurion arms stuff was any good. Glad to see someone talk about them. Thanks Chad. Was going to buy an upper and lower but was'nt sure about the quality, now i am.

[@mattmarkowski909]

I’ll second them. I have a complete Centurion build from a SOTAR class last year in addition to several home builds as well as their barrel in my MK12. They are about as good as you will find. Just be aware that their upper receivers are thermal fit for barrel installation. I’m not the biggest fan of it for every build but they are still great uppers. Buy their stuff with confidence.

[@ryand8024]

Personally, I consider them one of the best for pure durability and ruggedness. Their qc is top notch as well. Buy them with the utmost confidence stranger.

[@ryand8024]

Oh and their prices are pretty damn decent all things considered.

[@WetWiIIy]

@@mattmarkowski909 iirc Centurion has ceased doing thermal fit on their newer uppers in the last year or so. Mine wasn't thermal fit.

[@jamaicanomen]

Amazing videos, what are your thoughts on the kak industry’s duel extractor, downward vents, sand cutter bcg?

[@muddyhotdog4103]

Id like to see actual dirt/sand tests with a standard vs sandcut bcg. Kinda seems like sandcuts on a closed/tight system like an ar15 carrier would create more points of wear and contact especially as carbon/dirt gets in around them. I picture putting gaps in snow ski's vs one long ski. It's a little different then the sandcuts on an FAL, and the tolerances around the carrier aren't as tight. But kinda a solution to a problem that doesn't exist with an ar15, and maybe even creates areas for ingress in what is a mostly closed system?

[@seanoneil277]

Each individual cut's ledges and groove can be a sediment diverter, but they also serve (each ledge of the groove serves) as an accumulator of debris focused on a finite point -- where the ledge/cut ends. That focus point can potentially increase erosion (BCG to upper receiver bore) but I say "potentially". But what's the reduction in jams/binds resulting from those relief cuts? I can't imagine adding them for visuals/theory alone, it's an expensive addition to the machining work. I expect they actually work as intended despite potential focused erosion points.

[@9mmthroatpunch211]

Theres a knights sand cutter on gun broker right now selling for $1,599.00 🤯

my only complaint about the centurians chromed bcgs; its just the carrier, i'd prefer it to be the full assembly, so i know its going to work the way it should. and i don't have to try and hunt down a viable bolt, which can sometimes be annoying to accomplish. otherwise; they seem to make good product. and i wish they had more stainless barrel options, but que sera sera.

[@user-md4vb5uh5l]

Over the years there's been the debate to download mags or not so that they seat when loading. If a loaded mag (fully loaded or not) is giving you problems seating on a closed bolt, is it probably due to the rails on the carrier not being in spec? This would make sense as to the main culprit of that issue.

Never understood the concept of defeating the sealed system properties of an AR and putting more ingress points for sand and debris to enter lol. I don't think there is even any documentation for the origination of these bolts in terms of user request (not for CMT but for KAC). They probably saw the FAL and were like "we can milk this from all the instagram warriors," and now they sell on the used market for $1000 LOL.
