Where can you buy an upper right now?

Quoted:

I love my 6.5cm rifles for hunting and I wouldnt feel like I couldn't be competitive at a match with them. If your serious about competition though 6mms are popular for a reason. So no most PRS NRL are not using 6.5. All about that no recoil, spotting impacts life. My shoulder is as fragile as my ego.

Quoted:

So with that reasoning, wouldn't you say 6mm ARC will be popular for competition/target shooters? Almost the performance of the popular 6mm's in an AR15 and less recoil with factory ammo. Seems like a home run to me. If it's popular in the competition/target arena it will eventually bleed over to other disciplines as well as long as the factory ammo is good.

Quoted:

Most of that shooting is not done with AR’s so unless they have divisions for them bolt guns in bigger faster calibers will continue to dominate.

Quoted:


Lantac and CMMG both say complete uppers are available.

Brownells and OdinWorks should have uppers very soon.

Quoted:
Anybody know when Proof will start offering their barrels to the public?  Looks like they are only supplying manufacturers for factory rifles.

Quoted:


CMMG says shipping delays of up to 10 weeks.  It makes me think they really don't have it ready to go.

Quoted:
Wow there's stuff up on Brownell's for faxon barrels too.

Quoted:

Anyone that makes good barrels available yet?

So what is the pros/cons of the 6mm ARC vs. the 6mm Dasher?

Quoted:
So what is the pros/cons of the 6mm ARC vs. the 6mm Dasher?

Quoted:

Dasher will do well into the mid 2800-2900fps range with the same bullets since it has more case capacity, but it isn't AR15-friendly.

Works great in short action bolt guns in PRS, and is very popular in that realm.

Any of the Grendel-based 6mm cartridges will be more in the 2750fps range.

Most of the loads for Dasher I've seen are using 26-30" barrels though, so they are really close to each other when you compare to same barrel lengths.

Quoted:
AMU definitely didn't adopt it.  Quite the opposite really.

5th Group had at least one Commander who authorized studies and testing to be done with the proposed cartridge, not much beyond that.

JSOC acquired a large sample of 6.8 SPC carbines, ammunition, and magazines and did their own in-house high volume testing without some promoter trying to influence the tests, and wanted nothing to do with it after they were blowing up guns repeatedly.  No responsible entity really had control and ownership over 6.8 at the time, so all kinds of deviations from any of the initial 3 chambers, bore specs, and cartridge loadings were happening and colliding with each other.

Promoters of the 6.8 had to be escorted off of Bragg at least once by uniformed MPs at the request of units who were tired of being approached without solicitation.

There were several of the early 6.8 proponents who then traveled to the UK Ministry of Defense small arms people (without any official business orders or status) and told them, "This is the new 6.8x43 NATO cartridge developed by SOCOM, and that you had better get on board or get left behind."  These MoD people, having had a continual relationship with the US for generations prior to this, wondered what was going on because they never had these types of interactions before.  If something was actually sanctioned for R&D for NATO testing pre-standardization, they would have been notified through official channels and representatives and asked to participate.

They contacted the official DoD reps in the US who said, "What?"  It ended up resulting in threats of Courts Martial for anyone who was caught with 6.8 uppers, mags, or even as much as a piece of spent brass downrange.  They ticked off a lot of people across services, within multiple elements of SOF, and foreign partners, as well as the FBI ballistics lab.

If someone wanted to write a historical account of how not to promote a cartridge, the material available on the 6.8 "proponency" would make you shake your head from page-to-page asking if people could actually be that ridiculous.  People were fired over it and PNG'd from multiple locations and agencies within DoD and Federal LE for misconduct, misrepresentation, and attempts at fraud.

Until I can buy 6mm ARC steel case blasting ammo for $5/box I’m sticking with Grendel...

Quoted:
This 6mm ARC hitting the streets is pretty cool. Stands a much better chance of filling the niche of an AR-friendly, low-recoil, technically capable medium-range cartridge.

This design stands a lot better chance of adoption than, for example, the .224V, which was a technical mess in execution.

Of course, three years ago, the gun rag crowd was certain that the .224V was it. Pretty funny then, and now.

Here's what I wrote on the the future of the "everyman's" practical precision AR chambering:

Have you listened to Lowlight on the Valkyrie? I know that's your world(rifle stuff) He really makes it sound like the initial problems are gone.

Quoted:



I agree 100%  I think its going to be a game changer for night time coyote hunting.

Quoted:

Why?

Quoted:
so, at 1000 yards, will it have enough velocity/energy to kill or seriously would a human?

Quoted:


Maybe. The biggest issue with the Valkyrie concept is (even if they hadn't screwed up the engineering on release) it's not nearly as optimal in a short (10"-18") barrel as a 6mm will be.

6mm ARC Just Released by Hornady

Hornady 6mm ARC Info Page

COMPARISONWHAT MAKES THE 6MM ARC BETTER?
.308 Win
The 6mm ARC delivers substantially less recoil allowing shooters to spot their own shots.
The AR-15 platform features a higher magazine capacity.
The 6mm ARC offers a 30 to 35% lighter-weight package (gun and ammo).

.223/5.56
The 6mm ARC achieves substantially better ballistics than the .223/5.56. It delivers less drop, less wind deflection and the ability to shoot accurate groups at much greater distance (1000+ yds).
.224 Valkyrie
The 6mm ARC gives hunters the ability to successfully hunt varmints and deer.
The 6mm ARC produces a larger splash signature that allows shooters to self-spot impacts and make rapid adjustments.

6.5 Grendel
The 6mm ARC delivers comparable performance from a wider assortment of bullets, making it a more versatile choice.

6.8 SPC
The 6mm ARC is a better long-range performer.

Why?

55's going even in the upper 3k velocity range in the weight of an ar 15 platform. Essentially have a 22-250 or 243 in a more compact lighter semi auto rifle.

Read the reviews, no reliable magazines.
Same song second verse ??

For as long as the Grendel has been out I have a hard time believing there isn't a solid choice.
