- We speak with Nathanial from Faxon regarding barrels, barrel manufacturing, chrome lining versus nitride and more.
If you're interested in learning what really is going on with rifle barrels, then this is the video for you!
1:20
Difference between chrome lining and nitride treatment.
3:40
High Power and chrome lined barrels being “less accurate”?
Stainless barrels for accuracy, accepting greater wear and tear.
History of chrome lining basics.
Nitride is not a lining, it’s a treatment.
6:50
When did the nitride process come to the market?
8:00
Chrome lining still makes more sense for machineguns.
9:10
The ACR took an unfair hit from the consumer base for not having a chrome lined barrel?
11:05
Nitride process is beneficial to other components besides just the barrel.
12:21
Is this related to stellite? The difficulty of manufacturing a stellite enhanced barrel.
13:50
What is QPQ, etc?
15:10
Nitride process is very similar to the older 1800’s process of case hardening.
What is case hardening?
16:05
How deep does the nitride process penetrate into the steel? Case hardening is usually only a superficial layer, for example.
17:20
Nitride for military arms?
18:15
Extreme example of high velocity projectiles, is that better with chrome or nitride?
19:44
Stainless steel that’s used for barrels isn’t really the “stainless steel” we think it is.
Why are stainless barrels considered more accurate?
20:54
Discussion about different methods of rifling a barrel.
27:10
Cold Hammer Forging invented by Germans in WW2 to accelerate barrel manufacturing.
USA used cut rifling primarily during WW2 and those machines are still being used today.
27:45
What is cut rifling?
29:00
Replacing a cutting bit for cut rifling, what about button rifling?
Deep dive into button rifling process.
29:50
Discussion about progressive twist rifling.
31:41
Accuracy then and now, what is acceptable?
34:05
Original M16 pencil barrels, how were they manufactured?

Thanks for having us on! look forward to future installments.
Faxon Firearms ..thanks for the info...I got 3 of your barrels and look forward to getting a few more...
Lots of good info here, Faxon. THANK YOU! After this I will definitely be looking into your barrels for future builds.
Faxon Firearms - I couldn't be happier with my 18" GUNNER profile Faxon barrel. I will definately be considering other Faxon barrels for future builds. The 14.5" pencil barrel with the pinned muzzle brake is really interesting. I really appreciate a company that produces inovative & original products.
great interview
Fui Gebhardt Ha ha!
Wow, I just learned way more about barrels in past hour than in my previous decades of shooting. Thanks!!!
As a materials engineer, I can vouch that the information provided is spot on.
As far as I can tell, you guys are the only guys doing these types of interviews. Considering they are so good, I would say you have found a great series to compliment your "field tests"
I am loving these longer format very technical peices and enjoying hearing from people in gun design and manufacturing.
When I ordered my upper I had to do a ton of digging on Melonite (nitride) vs chrome and I found a lot of incorrect tribal knowledge, assumptions because it was new and cheaper, and lack of data. I'm glad I went with a more accurate, longer lasting, and less expensive Melonite barrel. I'm also glad we are getting videos like this, this would have been a godsend a year ago.
FYI: One of the first military oriented firearms to use a nitrided barrel was the Stoner 63. During the Ichord Hearings, Gene Stoner pointed out that they had resorted to nitriding because no one had yet developed a satisfactory method for chrome plating a 0.22 caliber bore.
The following link will take you to the 1968 report "Materials for Small-Arms Gun Barrels." The report was assembled by the Defense Metals Information Center on behalf of the USAF. The USAF was particularly concerned with reducing the bore erosion of high velocity/high-rate of fire machineguns and automatic cannon. So the authors assembled an overview of all of the methods and materials available for making more durable barrels. On Page 16, they judge nitriding as being inferior to chromium plating. However, they note that chrome-plating over a nitrided bore would be better than chrome alone. That said, the amount of the improvement would not justify the added processing. Also of note are some of the exotic alternatives being considered as potential replacements for Stellite 21 liners and chrome-plating. (BTW: Stellite 21 is a Cobalt-based alloy, not Nickel.)
www.dtic.mil/dtic/tr/fulltext/u2/500112.pdf
Other reports on DTIC cover some of the experiments in which the uber-liners and platings were tested in barrels fitted to M60 and MG3 machineguns. However, instead of 7.62mm NATO, the test barrels were chambered for .220 Swift and later .22/30-06. These cartridges were meant as a scale test for the 25mm GAU-7 cannon, which was aiming for a muzzle velocity of ~4,000 fps.
There is one more method for rifling a barrel, and it is particularly well suited for materials like Stellite and its alternatives. That would be Electrochemical Machining (ECM). I know that FN has played with making full-length liners by first "drilling" the bore via EDM, and then rifling it via ECM.
Funny you should mention ECM rifling three years ago. Nowadays with Jeff Rodriguez and Deterrence Dispensed and many others advancing homemade firearms tech, ECM rifling has been brought slightly more into mainstream hobbyist builder awareness via the Liberator-12K and FGC-9. Real interesting stuff.
What's EDM?

15:40 the bromance has reached the "we finish each others sentences" level. :D
Thank you all for taking the time to dive deeper into this level of detail, we need far more videos like this. My only complaint about this video is that it had to end and couldn't dive even deeper into the respective subjects covered.
When I buy certain things, especially an AR, I'm not satisfied with one person's recommendations, I want to know advantages and disadvantages of each option so that I can make informed decisions based on my needs. This helps a lot, thank you.
Thank you for really exploring this topic. Most gun info sources either don't respect their customers enough to go into this level of detail or they are withholding, boarderline deceving.
I absolutely love these interviews with gun manufacturers and designers. Sooo interesting and informative.
Rewatching this Q&A series with Faxon once again. Extremely informative and interesting.
Man this is an awesome series of videos..... Usually you have to look in several places/videos to get a comprehensive idea behind modern manufacturing but it's pretty much all right here. You guys did an excellent job as well putting this into layman's terms!
i just learned more about barrels in 30 min than i thought i knew/learned in the last 20 years. thank you. and faxon barrels have a new life time customer.
The recent Q&A videos with Hudson Mnfg., HMG, and now Faxon are some of the best content on your channel. Please do more!
Love these sorts of videos giving a peek at the inside of the industry. Please keep the coming!
I really like this discussion and it makes all the data on barrel tech more digestible. Ordered myself a pencil barrel, very excited to build.
We tested stellite barrels for the MG51 when we had new means of production to replace older designs. The good was that it fired reliably and accurately at a cherry red. The bad was the auto-ignition and the broken cases at that temperature. And 20 000 usd per barrel was what prevented us from adopting it.....
Please do more of these types of videos! I love the content! Unlike my day job as an engineer, this stuff gets the inner engineer in me excited and passionate again.
late to the party but soooo happy you posted this series as I love to Nerd out on things like this. Great series and Thanks big time for Faxon stepping up and sharing so much of his thoughts.
As a Mechanical Engineer, what a fascinating interview! Thanks to all three of you gentlemen for asking intelligent initial questions, simple easy to understand explanations to the questions and great confirmation questions and explanations to them. I have become very interesting in Faxon barrels going forward as a result.
Thank you for this Q&A series. This far, far exceeds the quality of purely anecdotal videos with more showmanship than education. Good stuff!
these info series you guys are doing are AWESOME... this one and the one regarding the new stg 44 are fabulous. so much INFO!
Watching this answered so many of my barrel questions in one place! Thank you so much!
Please do more of these, absolutely fantastic video.
Excellent video with perfect timing since I am barrel shopping. The video answered a lot of my questions.
Very cool! Many thanks to all three of you; I'm definitely going to have to go over this again. And again. And probably again. So much knowledge, so little brain.
This is really cool! I absolutely love these kind of videos! Keep it up. It's amazing. Nobody else does this.
More coming. ~Karl
Ian/Karl, this technical stuff is awesome. We need more stuff like this. You guys rock!
Thank you both InRange and Nathan for putting out all of this info; and making clear many of the misconceptions of chrome-lined vs. nitride treated barrels, as well as some of the other parts of the barrel making process. Hopefully this will benefit a lot of people making firearm purchases soon or in the near future.
these Q&As are amazing. please keep them going!
Really enjoyed that. Being a hunter and Mechanical fitter and a boilermaker welder. Made very good sense. Cheers.
Excellent Video - loved all of the data and perspectives. I would love to see the next section on barrel profiles.
A part 2 would be great, because there is so much more that can be talked about.
thank you for this informative video. I hope you continue to do produce and share more of these q&a type videos.
I'm really liking these q&a sessions with industry. I look forward to more.
Fantastic overview. Thank you Faxon and Inrange.
What a great guy this Nathanial! Really interesting subject, I'll definitely check the next ones in this series as well.
That was a really enlightening video. I would love to see more like this in the future.
I love these Q&As. Great educational experience.
Excellent video on barrel making, coatings, rifling, stress. Really interesting info.
Thank all of you for this Q&A ! It was great !
finding a wealth of knowledge on your channel. Thanks for the great work guys!
Great interview. I'd love to hear more. Thanks to all for sharing.
absolutely FANTASTIC video, I love this stuff. Thanks guys! Really appreciate it.
I'm really learning a lot from these videos. Thank you very much
I just learned more about barrel manufacture than I had ever heard before. Thanks.
Awesome! & Thanks For The Reply! That Made My Day! You & Ian Are Two Of My Absolute Favorites!.. Have a Great Day & Vid Bless You Both!..-B.Burns
That was utterly fascinating. Thanks guys
This is exactly the kind of deep dive I've been looking for, and makes me feel even better about my Faxon barrel otw.
Great vid! I'm quite a material science and firearms buff but that shed a great deal of light on many questions that I didn't have an answer for as of yet.
This was very interesting, I look forward to a part 2.
Just found this video and it was great! I’m learning a lot about barrels now and that’s great too.
i LOVE STUFF LIKE THIS. i LIKE FACTS AND LOGIC WHEN PURCHASING PRODUCTS.
i think i watched this whole video mouth agape. i am going to have to watch this again to absorb 1/2 this info.
thank you fellas
great information covering the barrel manufacturing process.
Love the tech Q&A,s you guys are doing lately.
Just another reason to love InRange!!!! Great episode, keep em coming.
Great video. I learned a lot. Keep it up and do more of these.
I would enjoy a lot more of this. I only understand at the concept level, but it is still very interesting.
These tech interviews are amazing.
Thanks, awesome discussion. Cheers.
Makes me appreciate my new nitride AR even more
thanks for this video please do more of this :) VERY informative
This is amazing, well done. I've just contributed to your Patreon account. I'd selfishly be interested in a discussion about gas port size/barrel length/dwell time.
Hans Schultz Oooo. That's a fun one!
Faxon Firearms I'd like to chime in with a desire to know more about polygonal rifling and traditional rifling and certainly of any other methods if they exist. Looking forward to another session.
We think that will be in the next installment.
Listening again & boosting my Spectrumosity
Great video! I love nerding out on this stuff!!!!
Great stuff guys! Very helpful information. I’ve got a faxon barrel on the way👍🏻
Awesome content. Keep them coming. I learned a ton!!
Good stuff. I really like these industry q&a videos.
Thanks for this video. It answered a lot of questions I had.
love these videos! Hope to see more
Nathan, thanks for all the amazing information in these vids! And thanks to your wife for her patience letting us have you for an hour. ;)
I wish I had money for patreon, you have taught me so much.
Just do the $1 a month. I am.
Very informative and look forward to hearing part 2. Thanks guys!
This is fantastic. I love learning about metallurgy, maufacturing processes, and the how and why behind various things. The engineering and machinist viewpoint is extremely valuable. Kudos to Nathan for taking the time, and for his thorough and thoughtful explanations. Looking forward to the series. Any chance of inserting brief video clips of certain processes? If not from Faxon, maybe there is stuff in the public domain? Fantastic content. As soon as things level out i will be contributing on Patreon
Thank you guys so much for this, very useful information👍👍👍
great video! as some one how like to learn some of the sciency stuff that goes into firearms like this and for example the new stg44 build, i really like getting the info from the companys and not trying to weed out the good and bad info scattered throw forums, word of mouth, opinions and just the plain old interweb. i hope you keep it up with these companies and find other companies willing to add to your play list.
Great video. Hope to see more of this series. FYI loving my Faxon pencil stainless barrel.
dollarbillme Thanks!
I scored a free (lightly used) Faxon 10.5" pencil barrel for my Aero Precision build. Good to know more about the background of Faxon and barrel manufacturing in general. The heart of the rifle is the barrel, I'll see you in part 2!
Spectacular. My Metallurgy fantasies are satisfied. For now.
Wow that was a great video that answered a lot of questions. 👍👍 great video
Such a good channel, I can't believe you guys don't have more subs by now!!!
I've been thinking of buying one of these. Thanks for the video!
As someone who has studied a lot of material science i find this whole discussion very interesting
Great video. A lot of useful information.
This was a fantastic session, very informative and interesting!
Glad you enjoyed it!
Crazy you guys happened to interview Faxon. I just ordered one of their barrels. Haven't installed it yet, but it looks well made. I got the nitride finish. Nitride, Melonite, QPQ, has been my new favorite treatment for the past year or so.
Thanks!
Yes, part 2. Please!
Actually the manufacturing and chemical processes are really interesting. In itself this could be a series no doubt.
So much information! Thanks!
Well I've been shooting for quite a while and I've seen the improvements over the years, and was amazed at how inexpensive MOA rifles have become, I'm breaking down and starting look for my first AR build and will check out Faxon for sure. Thank you for the information.
Thanks!
Love these faxon vids. Great info!
This is a damn interesting chat. Do more!
I loved this interview
Waking the dead here but this video is amazing. The amount of information here is crazy
awesome real information thank you guys .
Very good explanation!
Very, very good. Thanks!
Interesting stuff as always~
