GRINNELL, Iowa (June 3, 2020) – Brownells unveiled a line of exclusive barrels and complete uppers chambered in Hornady’s newly-announced 6mm ARC – a cartridge designed to optimize long-range performance potential in standard-sized AR-15 rifles.
Using the same bolt and magazine as the 6.5 Grendel, the 6mm ARC capitalizes on the enhanced ballistics of 6mm bullets. The 108 grain ELD MATCH load from Hornady lists a muzzle velocity of 2,750 FPS out of a 24-inch barrel.
Some models of Brownells exclusive AR-15 barrels chambered in 6mm ARC are in stock and shipping now. The complete uppers and other barrels are live for pre-orders and are expected to be in stock and shipping later in summer 2020.

I am still trying to figure out why BA didn’t make an 18″ barrel with rifle gas, especially when Brownells is having Faxon do one and Proof does one in rifle +1 gas.
I guess I thought 6.5mm grendel WAS the round “designed to optimize long-range performance potential in standard-sized AR-15 rifles.”
New year, new boutique wildcat.
I don’t know, I feel like I’ve seen more announcements and support for 6MM ARC in the past few days than I’ve ever seen for 6.5MM Grendel. Here’s hoping this one sticks.
It’s a 6.5mm Grendel necked down to 6mm and with the shoulder slightly retracted. This kind of necked down Grendel wildcat is quite popular in the long range shooting community. The Grendel is a great case and the 6mm seems to be the sweetspot in long-range shooting nowadays, so a 6mm Grendel is a match made in heaven. From what I’ve seen until now, it seems it will blow the .224 Valkyrie out of the water and anything else doesn’t even come close: fits in the AR-15 magazine format because of it’s OAL, has low recoil (in the grand scheme of things), bucks wind better and drops less than its competition. In order to have better ballistics you need to go to a bigger case in a bigger mag and bigger receiver (6mm Creedmor, 6×47 Lapua, 6XC etc.) which will be more weight to lug around and more recoil. Hence, this seems like the best thing to fit in an AR-15 until now, it’s tried and tested in the community and it seems that they organized a good launch with strong industry support. What more can you ask for?
Huh… pretty good explanation, thank you for that.
