What You Need To Know When Selecting Your AR15/AR10 Barrel

DUDE NO ONE IN THE FUCK USES A BAYONET LMAO

i couldnt get an AR (because new york state :/) so i opted for a kel-tec SU-16A

its a pretty cool rifle but its kinda fragile, and the pic rail is made outta polymer

So far i have liked all my 4150 Nitrided barrels and BCGs, in fact i prefer the Nitrided BCGs to the parked and chromed ones. As i understand the main benefit of a chrome lined bore is heat dissipation in full auto fire. It's also important to remember that a standard AR today is better made than any AR Soldiers and Marines took into the jungles of Vietnam.

I used to shoot about 9,000 rounds a year in Service Rifle Competition. Best accuracy was from button rifled Douglas SS barrel chambered by Compass Lake Engineering with CLE chamber. Lots of mid range X’s up to about 1,800 rounds. Experience also suggested slightly less accurate cut rifled barrels would get good results up to about 3,000 rounds. And BTW my 6.5/284 with cut rifled barrel has needed rebarreling at 500 rounds. One more thing, my Service Rifle barrel’s front sight base is attached to barrel with 5/64th inch set screws, set to flats milled on the barrel. It allows initial no wind zero to be made from front sight with rear sight at mechanical windage centered. No problem ever with screws becoming loose. Loctite is a good idea nevertheless to assure screws stay tight.

The radiant heat transfer of surfaces, the color can impact heat transfer. The blacker and less shiny the surface, the better the radiant heat transfer typically is. So that’s the technical reason for your claim. Material thickness influences the rate of heat transfer and heat buildup.

😂 "if China invades"

I know he wasn't serious. The U.S. vs China is just a funny concept to imagine. They wouldn't even make it to the beach.

You know absolutely nothing about thermal dynamics 😂.

You had me until "socialist takeover." Lmao! You guys don't even know what socialism is, and it's both hilarious and sad. 😂

I thought that stainless steel was better at managing heat like a cast iron skillet vs a regular skillet and also why is the 409 performance stainless steel for headers to manage the heat better ?

A way to test this is take a stainless barrel and a 4150CL and a 4150 nitrided, fire five rounds at an indoor range (air conditioned for control temp). Test temp at completion of firing, 30 seconds, one minute, five minutes, and 10 minutes and 15 minutes, 20 minutes, and 30 minutes. That will give you your controlled environment temp of each type of barrel hardness/lining, and statistics that can be graphed for visual aid.

Nobody gonna talk about how this dude looks like a particular Navy SEAL?

JFC, get to the point. Nothing like getting eight minutes of information in a 17 minute video.

Queue the one million opinions on gun barrels. Much of which will just be unhumble attempts of men to assert themselves. Which is ok. We are all just men after all. Nice when someone begins with "In my humble opinion …" If they end up saying they know what's best for others, or flat out just calling people "moron", you know it's just all about them.

“If China invades”😅👍🏼👍🏼😉

My friend, in a nutshell, I am a good shot and want a chrome-lined ____? What? Thanks.

So when you say shiny you mean softer metal, Dark metal is higher density steel, higher carbon content. Softer steel will of course not handle full auto over time compared to high carbon steel. I did not know that barrels are pounded/compressed during the rifling process, makes sense for compressing the steel harder for longer life.

This is all really good information. I like your real life perspective so thanks for making this. I'll just stay with 4150 barrels.

I need an heavy barrel but when I picked up my friends hbar I noticed it was a lot heavier than my other friends non heavy barrel ar, does a heavy profile barrel really make that much of a difference or was it probably that along with other possibly cheaper components weighing it down, if it was the barrel well I want an accurate hbar barrel that is very light and won’t have the weight issue while still having the “heavy “profile” any advice?

Thanks for the info 🙂 getting a 18-20" bca in black and heavy

Great barrel information! Thank you!

Thank you for the explanation

Knowing the data and wanting to have knowledge Don make ya a nerd it makes ya a better gun owner. Yer pretty small minded

“There was shot everywhere, shit on the walls, shit on your shoes…..” wait….shit in the walls? Thefuq?

Don't buy one made for that A-frame looking front sight, gas block, bayonet mount etc. very limiting for customization, no adjustable gas block, hard to fit a free float handguard, and so on, most ARs in 5.56 are overgassed.

I buy a stainless barrel and install it .

Can I just have a written barrel hierarchy please. That's all I need thanks.

cool video, lotta good information

Guns will never be outlawed in America, I moved here from Europe. This is how to country won its freedom it would be pathetic to turn the greatest country on Earth 🌎 to the shitty countries in Europe.

Chrome lined is the best I was unsure until I shot out all my chaper barrels without chrome lining like the century AK74 NOT chrome lined. Nitrate Adams Arms is decent but chrome is the best. My vepr had 9k rounds and still shooting like thr day I got it, chrome is king.

ok yng man which one is better 4150 r 4041

I just wonder what type of SS iraqvet was using. Because the 416R SS, I've only ever seen in a HBAR configuration. And this metal is typically what all Artillery barrels are made from. And if you get a caudled barrel you're cold bore shots are sub MOA, and grouping should improve as it heats up.i know that sounds ass backwards, but that type of riffling i believe is far superior than the traditional rifling

looking into building my first AR pistol any advice?

The majority of hammer forged ar barrels are 4150cmv

Melonite adds durability to a 4140…it's not ideal but it's better than straight 4140…melonited 4150 is excellent

Why does a AK made in a 3rd world country out last a AR made by American citizens? Seems crazy to me

Who cares. Good video, but 99 percent of you will never outshot your BRL life.

I don't have a problem with data. I just prefer Picard.

i built my AR with a 16" ss bull barrel. its not made to be "tactical", but merely for long range target and popping a coyote when needed. its a 1:9 twist so i can feed a wider variety if freedom seeds if i cant get to my personal stock (all home grown loads).
keep up the great work.

A bit confused here….what's a minacular level?

Your doing a great job. Thank you for the video.

Chrome lined barrels have less friction,with less friction comes less heat heat !!!

There are stainless steel barrels that are nitrate over coated !!!

I don't own an AR15, I'm strictly a Hi Point man ! But I find your info fascinating

what are you talking about a lot of stainless and nitride barrels are more expensive. chrome lined is usually the cheapest.

Probably shouldn't talk about hardness and testing, since you have no idea what you're talking about. 35 year pro here.

Only time any of this ever actually matters or will effect real life shooting is if your taking full auto. 99.9% people will be served fine with either . and see no benefit from chrome. We gotten so good at making specific metals for specific purposes. Just 👌

Always enjoy learning something new. Thanks. However, a few extra ounces on a better barrel is a non issue if humping for long periods of time. A half century ago I would go camping for 15 to 30 days at a time for a year. Up and down mountains, 100 degrees, 80lb ruck. Twelve qts of water weighs about 25lbs. The amount you carried depended on the terrain, monsoon season, quality of H2O. Water is life. I carried 600 rounds in 32 magazines. That was 16 to 18 lbs with pouches, bandoliers. Scrimp on ammo and you die faster. Rations, lightweight LRP's, heavy canned c-rations, resupply every 4 days. Eat the heavy stuff first. A half dozen grenades, 3 or 4 trip flares, 2 or 3 smoke grenades, 2lbs C-4, Claymore mine, extra battery for radio, box of blasting caps, machete, poncho and liner, 200 round box of M-60 ammo(20lbs), maps, code book, cigarettes, camera, insect repellant, survival knife, steel pot. So, you get the point that a better barrel, even at 8 oz, will not affect short or long term impact on body.

Second time I watch this video (I'm a subscriber). But I found more infornation at In Range TV (Faxon Q&A: Barrel manufacturing… etc) from 3 years ago. Found more data and I think it can be very useful for us "newbies"… although I will be 74 this coming April!

I'm glad you mentioned staking the set screws in the gas block because if you are using a low profile gas block that's probably your best option.

🤣🤣🤣🤣 you took your torch inside a grain mill & lit it???😳😳😂😂
You're lucky to still be here!!
