Magazines for 6mm ARC

Elanders greater than 10 rounds have sucked ass for me in 6.5 Grendel. The 10s have been fine. ASC (all sizes) have been the best for 6.5 Grendel and 224 predator, for me. I’d expect the same for 6 arc...
 
Some guys don't like ELanders, but they must have variations between different batches because mine have been great, both 17 and 25 (?) round versions from Brownells. I also use ASC stainless mags and they're good too especially if you need the OAL, but in my rifles (one Grendel, three 243 LBCs, and a handful of 6.8-based wildcats using the same mags) the Elanders seem to be a little better. I use the same mags for Grendel-based and SPC-based cartridges, after some experimentation showing no functional difference. YMMV of course.

Someone posted pics of their Duramags for the Grendel & 6 ARC in the 6mm ARC thread; those mags seem weird to me because they are 7.62x39 bodies with a lot of curvature, despite the Grendel case having less body taper than the 5.56. He seemed to think they worked fine though. I can't help but think those Duramags were just a business decision to re-label 7.62x39 mags that weren't selling, or something like that. Everyone else's Grendel mags are fairly straight bodied like 5.56 mags.

E-lander 25's work well for me if I run unsuppressed. Suppressed they get dirty and the bolt out-runs the ammo. Works okay for a while but they need frequent cleaning with a light film of oil.

ASC 15 rounders have been awesome suppressed or not.
 
Huge (former...) E-Lander mag fan here. I have six E-Lander 17-RD 6.5 Grendel magazines that run flawlessly for me with 6.5 Grendel, 6.8 SPC, and .224 Valkyrie in every platform in which I've tried them. Never one problem!!!

When I decided to build a "test platform" 6mm ARC, I just pulled the barrel and bolt out of my test platform .224 Valkyrie.

The E-Lander magazines that all ran with nary a problem when the rifle was a .224 Valkyrie would not feed reliably in the same rifle rebuilt as a 6mm ARC with more than three rounds in them. With fifteen rounds loaded, I could not get a round to strip out of the magazine. The tip of the bullet would nose-dive into the front wall of the magazine every time.

It looks to me like the forward rib in the E-Lander magazine body is interfering with the shoulder on the 6mm ARC case. It could be I have magazines all from a particular run with the same issue, since others report good results with E-Lander mags. I tried a different lower receiver, just to see if that was a factor - same results.

Next, I tried other magazines - ASC, Duramags, and others. Mixed results. Duramags to me are unnatural in appearance. I don't think use them if they did work 100%, but they're among the better functioning ones I tried.

Then, fortunately, a friend involved in the development of the 6mm ARC electro-optics suggested magazines they used with good success from an outfit I'd never even heard of before: Brenton USA.

Extremely agreeable people make up Brenton USA. This is a place where real people answer the phone and can actually answer your questions with authority. The boss himself may be the one you get when you call - I did. Among other interesting things, they build a handsome looking straight body 15-RD stainless steel 6.5 Grendel magazine, blocked to four round capacity for hunting.

Don't try to buy a straight 15-RD version. They just sell them with one way, apparently. I imagine they have a good reason. It's simple to yank the offending piece of red plastic out by simply pulling off the floor plate. I can't get but fourteen rounds in mine, but at least now I have a magazine that is working 100% of the time.

My groups are noticeably better when my gun runs correctly.

Why not just run the 20rd/10rd/5rd Duramags? If the curve of the 26s bugs you, they have less, and they function 100% without being a blocked mag in an odd capacity from some hunting company. Did you have any functioning issues with the Duramags or is it just an aesthetic issue? I’ve got more than two thousand rounds downrange from them in both an SBR and a full length setup and have had zero magazine issues, even with a good amount of rapid fire, to include some time in a FA lower. I do shoot suppressed and unsuppressed. I’ve not seen a single person running them in 6ARC have any issues; only @Yonderling griping about taper, hah.

I would also prefer a straighter bodied magazine, but not at the expense of functionality, capacity, or availability. If someone comes out with some straighter bodied 5/10/20/25rd magazines that run 100% I’m all ears but buying blocked 15rd magazines bugs me. It’s an odd capacity, and I don’t like blocked magazines when I want lower capacity; I want smaller magazines.

If that Brenton place is great and the owner is willing to talk, get them to produce some magazines most people would want to buy! I’ll call them tomorrow and see what they have to say. Perhaps if we all ask, they’ll consider it. Until then, 100% functioning banana magazines will keep working for me...

Griping, no, but maybe it's not worth pointing out red flags to certain people if that's the way you take it. Some guys get way too defensive about their purchase decisions; there's no reason to take something like that personally. If they work, great, but it's pretty clear they used a x39 mag body without thinking about body taper. It's really surprising you don't have some bolt over base malfunctions, unless you just aren't using full mags with those 26rd versions. With the shorter mags or just less rounds in the mag the body curve doesn't matter.

And seriously, read my screen name again. No L. You can always spot the city boys, trying to spell it like some sort of stupid hobbit name or something.

I guess the 'hah' was lost on you; it was intended as a joke. I'm not defensive at all about this topic, I could care less what magazines people use, and I definitely don't feel threatened by your comments. I am using full magazines. There are a lot of reports on these magazines in 6.5 Grendel with no issues, as well. I actually completely agree, I am not a huge fan of the taper. I would think my previous post made that clear. You seemed to leave that out of your quotation, as I'm fairly direct in stating as much.

I would also prefer a straighter bodied magazine, but not at the expense of functionality, capacity, or availability. If someone comes out with some straighter bodied 5/10/20/25rd magazines that run 100% I’m all ears but buying blocked 15rd magazines bugs me. It’s an odd capacity, and I don’t like blocked magazines when I want lower capacity; I want smaller magazines.

Just so we are crystal clear, I 100% would love to see "properly" curved magazines for this cartridge that always function. I've yet to find them, while these "improperly" curved magazines do. I had to tweak the feed lips on two out of the 30+ in various capacities that I own now, but other than that, I've had no issues. I'm pretty sure I was the one who bent them during transit, to begin with. I completely understand what you are describing as a theoretical problem. I have not seen it in practice, in a lot of different shooting scenarios, which is why I offered up my experience to someone searching for functional magazines. It's entirely possible in a different person's rifle they will function differently, but that has been my experience across the 2 lowers and 2 uppers I use for 6mm ARC.

Apologies I added an 'L', but I'm definitely not a 'city boy', not that it matters. I suppose I should retort that you can always spot the country boys, they have to resort to ad hominem attacks instead of addressing content. ;) I use autofill on this site for @ references, so the phone I was typing on must have autocorrected to some weird perversion of a disused word. I'll be more careful in the future to avoid offending your delicate sensibilities about the spelling of your forum name. 😂🤣 Hopefully the smilies get across the point that it's just a jab in jest, this time.

Again, I'm all eyes and ears if someone has lesser curved higher-capacity magazines that function reliably. All I see are reports of issues with E-landers and ASCs, and nary an issue with the CPDs other than aesthetics. I haven't personally tried the former two; the forum posts were enough to scare me off.

Looking for 10 and 15 round dedicated 6ARC mags.



So since it’s been a month how are those 6.8 mags running with 6ARC?

hahaha I wish I could get a craddack barrel in a month. I’ve got plenty of barrels from them and it’s easy to get them to shoot well but the turnaround time from ordering hasn’t been short. Got spooked with all the panic buying so got them before my build was done. I’ll update the thread once I run them.

I have a couple and they've worked great with my 243 LBC and Grendel rifles. But then again, I haven't had issues with ASC or Elander mags either.

It'd be interesting to hear if these work well for people who do have issues with other mags.

Regardless, they are a good magazine option.
