Build your own AR Barrel from a blank | 358 Legend barrel Build

Tha ks for a sharing this you cant find many vids like this.

Great video

Admit it. That very first barrel you ever made yourself, and went to the range to shoot for the first time…had you about ready to piss your pants until after that first shot. Haha! At very minimum, at least cringing worried something might go wrong on your first one. First one would sure worry me! 🙂

Your data you’re using is incorrect. I’ll give you everything you need if you message me. The internet is not the place to find data on barreling for the AR as most of it is incorrect. Good vid overall it just needs accurate info to fill in.

Too cool. I learned several things and the machinist's skills reinforces knowing how to use a tool is what matters most.

Eagle, if you know the material and/or brand name of that bit used to drill the gas hole. please share. I'd bought what I thought we really strong bits to dimple a barrel. Only to find them skating all over the place. Granted I don't have a big strong mill drill press.

You didn't use center drill first on gas port? My drill bits walk like crazy if I don't. Looks good, I learned a lot, will be checking my gas block next time. P.S. The chamber after sandpaper looks pretty rough, do you get scratched brass?

Great job, both for you and the man taking the time to teach you.

interesting to watch

Okay Kenny, now your showing off.. ha! Super impressive! You gonna molt your own steel on your next vid?

What a great video, man. Outstanding work. Lots of numbers in the metal industry, eh? 😁 I love that laser engraver. It's insane seeing the machinery that's available today. 👍👍👍👍👍

It is a special thing when the Machinist shows that each step of the process is a project in it's own. His hard to wrap your head around, however,, Companies used to manufacture firearms using that as a build process. Now, don't get me wrong, in these modern times with polymer technologies the process is even further reduced. Ruger had is figured out producing steel firearms with acceptable profit and with all firms these days with the advent of polymer, they simply made manufacturing too competitive for firms like Colt and Smith&Wesson to produce their steel firearms and make competitive profit. It's all about mass produced speed of manufacturing. Anyway, like it or not the page has turned. That's my small rant,, hehehe 🙂 -Dave

EE, great vid. I am never gonna do this work myself but would love to find someone to do this as I have never been happy with the available twist rates. 1:16 for the 350 and the 1:14 for the 358 seem too slow for the heavier rounds. I see you went with 1:11 and I am interested on what weight shoots best from this as well as how it handles the lighter weights. Looking forward to the testing!

Great content as usual Kenny! I don't know beans about machining BUT I do know high quality work when I see it and that was some good stuff!

Damn brother! That is a super sweet barrel!!! 👍🏻

Very cool , that is some nice equipment . 🙀🙀🙀

The gap between the barrel shoulder and the gas block is to allow for a handguard cap.

The math in all that gave me a headache……lol
Great vid sir👍

That turned out great man. You are very fortunate to have a good mentor like that👍🏻

Thanks for a little lesson on how it's done.. I've looked at barrel blanks before.. but have no tools to finish the project.

You did this build like all 350 legends should be.

I've got a question for you? Can you build me a 7.62×39 that will use the 6.5 grendel bolt! They are both based on the same case but, the 6.5's bolt face is much more robust! Obviously the main difference is the barrel extension and bore diameter👍🇺🇸

Very interesting. Love the precision equipment. Wondering about 358 Legend…are you attempting a new wildcat or is this what you think Winchester should’ve called the 350 Legend?

Professor in the lab!! Awesome work!

That was outstanding. Thank you!

Very cool. What diameter barrel did you go for? I noticed the title says "358 Legend" and the barrel "358 Eagle". Wasn't sure if this was the .355" you often see quoted for 350 legend, or if you went with .357"-.358".
That was interesting about roughing up the chamber. Makes sense though, since you want the brass to hold until pressure drops and the brass is ready to be extracted. I'm glad you guys showed that, I've considered polishing the chamber in the past to help with extraction / feeding.

Hat off to you Sir, that’s some nice work.
