Geissele 6 ARC in service with SOCCOM, some hands on comments.

Ok, I'll throw this in to bring the simmer back up to a boil. Are not the 6 ARC and 6 Max identical ballistic-wise? I know there's much discussion prior just in this thread about the strength of the Grendel bolt but the 6 MAX just makes more sense to me with the common bolt. It seems to be the cartridge equivalent to Betamax vs. VHS, hd dvd vs. blu-ray, etc.

I don't have the knowledge nor the inclination to know all about the performance of small arms where my stolen taxes are being sent in eastern Europe. To an old cold war REMF, it looks a lot like WWI with drones and .338 Lapua snipers. It would seem like not a whole lot for Russians to spin up AKs in 6.5 Grendel if they're not happy. Does anyone know if that's been done?

Lancer 300 BO mags with the metal lips feed 6 ARC rounds just fine.

At least for me in the last 300 rounds or so.

They are pretty similar if you are shooting bullets under 90 grains. Otherwise the MAX started to lose case capacity with the heavier, longer, more aerodynamic bullets.


Personally I’d love to see a 75k psi 25 arc or similar to launch a 75 vmax very fast. Maybe Hornady could develop a 90 ELD VT and 120gr ATIP too

If bolts are extractors have been a problem for some then what do you think is going to happen with 75k psi velocities in cycling?

I think it would take a steel base and maybe a nonstandard receiver / bolt. A guy can dream right?

I haven’t really noticed my proof barrels tending to speed up… I have taken my LMT gas gun and made loads for it so that it would shoot at the same velocities as my old guns. But that’s an MWS, and we’re not talking apples to apples here…
