Looking for any and all reporting you can find on 6 ARC efficiency and performance in shorter barreled setups.
The interest in lighter weight builds, whether that be pistols or non-SBR 14.5” (pin and welded muzzle breaks) rifles, for hunting applications is going to be a new focal point with 6 ARC.
Comparisons welcome between 6.8 / 6.5 grendel / 6ARC in 14 and 16” barrels if you find articles or the time to test and report back here...
I found a proof research 18", stainless, online in stock so I went ahead and bought it.
It's only 18" and I really wanted a 20" but right now they're all scarce as hen's teeth lol.
So they told me it's actually "in stock," not just "order and we'll back-order ya" type of thing, so we'll see.
The real question mark for many potential 6 ARC users are good magazines. Unfortunately all the common 6.5 Grendel magazines suffer from random quality control issues.
Since there aren’t a lot of members on this site I thought I’d pass on some info. C Products Defense/Duramag has finally released a twenty round curved body 6.5 Grendel magazine. Aim Surplus had these mags in stock a few days ago.
As it stands right now the current 6.5 Grendel magazine manufacturers are:
ASC which are also rebranded AR Stoner from Midway USA, with 5, 10, 15 and 25 round capacity.
E-Lander with 5, 10, 17 and 24 round capacity
C Products Defense, Duramag with 5, 10, 20 and 26 round capacity.
Amend2, 10 round polymer.
D&H sold by PSA has a 10 round 6.5 Grendel metal mag with orange follower.
I sent an email to Lancer today requesting they introduce a new polymer magazine that will work with 6.5 Grendel and 6 MM ARC. It might not hurt for a couple others send in a request for 6.5 G/6 ARC magazines.
If anyone is aware of any other AR-15 6.5 Grendel mags please advise.
I’ve read some users of PRI 6.8 SPC magazines work with 6.5 Grendel. It might be worth sending an email requesting a 6.5 G/6 ARC mag from PRI.
I saw where Midsouth Shooters Supply advertised ProMag 6.5 Grendel/6.8 SPC mag but I never investigated further with ProMag past history.
Like most short range benchresters I have many, like hundreds, of Lapua 6ppc brass that still have a great deal of useful life left. I'm thinking of building an 6ARC for my grandson so thinking it would be nice to be able to use all that great Lapua brass. So I'm looking for your thoughts on the feasability of being able to fireform the PPC brass, just blow it out longer. Any problems forseen with that approach?
Ok while I'm at it what about the practicality of taking one of my PPC barrels and just running a ARC reamer into it for a rechamber job?
I first heard about this a few months back and was going to build a Grendel. But the 6 ARC caught my interest and I started doing research on it. Although info was limited, and not much was being released about all the testing. I started gathering parts needed to do a build, whether it be a Grendel or an ARC I wanted an AR in a different caliber besides 5.56, and I am not into pistol caliber, 300 BLK just doesn't do much for me. I also kicked around doing a Valkyrie.
About eight months later this came to fruition, thanks to the fine folks at Odin Works. They build some fine barrels and are just great to deal with.
Odin Works 18" 1X7.5 twist, Rifle +2 gas, Odin adj gas block, Odin Atlas compesator, 416 stainless, hand lapped, Odin BCG, Luth AR rifle stock, Vortex Viper HSTII 6X25 50mm scope, and a bunch more good stuff.
Just found this site this morning, and just received my Odin Works barrel and accessories this morning as well. Spent the day yesterday Cerakoting the rail upper and lower receivers as well as the stock. really looking forward to learning more about this platform. And being that we are all on the front side of this we can all help each other out as we learn about it. I reload... thank God. As this ammo seems to be made out of unobtainiom, I got lucky and scored 440 rounds, some of it I have not received yet. Should be seeing it today or tomorrow, utill thenI have 240 rounds to play with for now.
I sent an email to Criterion barrels about a week ago. Here's the response:
Paul,
We have already produced barrels in 6mm ARC and are currently evaluating the cartridge. This requires evaluating several different lengths, twists, and a wide range of ammunition. After we toast a few barrels we will make an evaluation on the viability of a full production run. I greatly appreciate your interest in our products, please let me know if you have any other questions.
