AR-15 Article: Some Won't Like It, But....

[N555]

The 6mm arc is the replacement for 5.56mm. Yeah color me skeptical.

All the other 5.56 replacements from years past are saving you a seat.

I don't have a 6mm arc brass sample but I think it's a fatter case head than 6.8spc. If it's fatter, the mag holds fewer rounds, or if it holds 30 they have to make it longer.
Will likely use approximately 100gr bullets, so the rounds will weigh, what about 1/4 more than 5.56?
It will be better out around 500 yards, where it's almost never used. Virtually all war zone shoot outs start and end with in 300 yards and most of those are at less than 100yd. The only conflict where you heard about longer range engagements was Afghanistan, but we ain't there no more. Next war seems like it could be in eastern Europe.
Some one walks into a gun store and says they are a Navy seal my BS detector is already on high alert. Extraordinary claims require extraordinary proof.
They compare 6.5creedmoor or 308 to 5.56 for killing coyotes. Well guess what when you are hunting something that's trying to run away from you the longer range gun is going to be a lot better.
What do you think?

I wouldn't trust a thing that comes out of that guys mouth. But if I were using a ar-15 in war I'd take the 6 arc.

 

[Goosey]

Not watching the 52 minutes to see what he says. 6mm ARC would be a step backwards because of weight, recoil, capacity. Probably worse reliability in an AR as well.

Sigh….

Welcome to January of 2021… Mama always said you was a late bloomer…

The 6 ARC was developed and subsequently selected for a specialty application where the crap you’re complaining about is less relevant - it is NOT a carte blanc replacement for the 5.56 in all issues of the M4 - wasn’t proposed as such either. It’s doing very well in the civilian market, despite whatever whining you want to do NOW, almost a year and a half late to the party…

Agree with you, tactical tony wannabe. There are several very popular "gun guys" on the youtubes that are just so flat out wrong on some of their videos it boggles the mind.

He is just another internet expert.

I wish I had archived all of the "news" I have heard over the years about all of the new calibers and guns coming out that were destined to take whichever shooting community by storm and make everything else obsolete. It was especially entertaining when I obtained such "breaking news" from the internet but didn't hear a peep about these things at work- at jobs in the twilight of my military career when I worked in a Special Operations unit for/with/through R&D and force modernization efforts, and was in direct communications with the people in Crane, Indiana who test and integrate all SOF weapons and ancillary equipment. NSWC Crane is where most new items that end up in SOF weapons inventories, and eventually (mostly) migrate into the "mainstream" military- are "birthed". I do know some civilians that play with things like the 6 arc who speak highly of it- like so many rounds in the past that were going to be the new hotness- only to eventually fade into obscurity with a few niche supporters.

The video dropped 3 days ago and I usually ignore any new cartridge for at least 5 years, as to not pay top dollar for something that's likely going to fail.
Also I'd rather be a late bloomer than someone who peaked in high school.

 

[someguy2800]

If such decisions were made based on technological merit alone then the 5.56 would have been replaced many times now, but they are not and never will be. When the AR platform and 5.56 are eventually replaced, their successors will also probably live on for decades after they too are no longer state of the art technology.

If were stuck on an AR platform I'd take either 5.56 or 308. Gotta be able to get ammo resupply.

 

[Speedo66]

When you've got so much capital tied up in a particular arm and ammo, it's tough to change.

That is, unless some senator's or president's son with ties to a manufacturer wants the military to use his new product...

 

[Heir Kommt Die Sonne]

Some one walks into a gun store and says they are a Navy seal my BS detector is already on high alert.

If I was a Navy Seal, I wouldn't care to talk about my profession in a gun store. If anything I prefer to act naive and be like "ohhh gee this Sig p226 sure feels good in my hand"

Next war seems like it could be in eastern Europe.

Time to bring the M14s out of storage because they were designed exactly for that.

If it's fatter, the mag holds fewer rounds, or if it holds 30 they have to make it longer.

Bring serious this time, I dont get this thinking for 6.5 either. The 300 blackout has already solved the short comings of the 5.56, albeit just not as accurate at distances beyond 300 yards. Britain already bought a bunch of .300 Blackout a few years ago (for what purpose we dont know) and the Dutch Navy (i could be wrong) has a special forces unit that uses .300 Blackout.

 

[mavracer]

No doubt that the 6mm ARC has pretty ideal ballistics from a Stanag magazine length cartridge. The 105-107 gr 6mm bullets carry more oomph down range and can be driven fast enough to matter. BUT replacing 5.56 comes down to economics. Like the military I'm already invested in 5.56. I already have the guns, ammo and mags, with 77gr SMKs it does a good job and is very accurate out to 600 yards if I need more range I already have a 308 with 175 SMKs available.

 

[mshootnit]

Not so sure that ballistics trump terminal performance if we consider common small arms. Long range specialty weapons are a different thing. Right now runni g into resupply issues with Ukraine because they run eastern block calibers. Hint: if you think you might need US support someday, switch over to our stuff.

Not only that, NATO compatibility.

Let me know when line Army units (not SOCOM) are getting fielded a new caliber and I will believe a change is actually coming.

Nobody has ever claimed this would happen, except for people bitching online that it won’t happen…

Ah, yeah, plenty of people and groups have claimed cartridge "X" will be replacing the 5.56mm as the standard issue cartridge over the last 20 years. But what do I know- I am just a prior service Army Officer coming up on 20 years working for a company that focuses on DoD RDT&E, not an internet expert with a YouTube channel.

Yes, there have been solicitations to explore replacements for the 5.56.

The solicitation which elicited the development of the 6 ARC was not such, and no claim has been ever been made by anyone other than online fools that the 6 ARC was meant for any kind of broad scale replacement of 5.56. So while OTHER solicitations have been made, as I stated originally:

When I am at work I wear a shoot me first polo type shirt. If I go out to lunch I pull that off and wear the tshirt under.

I don't know- Maybe we are saying the same thing or maybe not, but OK.

Yes, I don't believe there is any home grown US made 5.45 ammo.

 

[marksman13]

Didn’t we do this exact same thread last month? I mean, same video and everything? There are several cartridges that outperform the 5.56. Period. None of them are going to replace the 5.56 any time soon. Period.

Clicking on links increases views and eventually popularity. Based on these posts, I'll pass.

May be a re-post of the video. May be a similar video, but we play this game at least once a month. There are two camps on this issue. Very few people are willing to hang out in the no-man’s land between those camps. No amount of conversation is going to bring the two camps closer together.
