Update on the consumer Bushmaster ACR

Adam Heggenstaller has just posted the first concrete detail of the consumer Bushmaster / Remington / Magpul ACR …

The cool thing here–other than it being a brand-spanking new gun that you can get your hands on real soon–is the ACR’s modularity. The consumer version will be offered with a 16.5-inch barrel, but Bushmaster will also be making barrels with lengths of 10.5, 14.5 and 18 inches. The first version of the ACR will be chambered in 5.56×45 mm, of course, but since a tool-less disassembly allows you to change bolt heads, barrels and magazines, the ACR can be user-configured to run with other cartridges as well. Ongoing development will focus on the 6.8 mm Rem. SPC, 7.62×39 mm, a yet-to-be-disclosed 6.5 mm round and, get this, the .30 Rem. AR.

  • I look forward to seeing what the new 6.5 cartridge will be. If it can compete with the Grendel and ammo and reloading components made available it’ll make the Grendel folks nervous. I really like the 6.5 bullet and might consider the new cartridge for a build on a new Black Rain Ordnance billet upper and lower I just picked up.

    Love the cartridge swappy-ness of it. Does anyone know what they’ll do about magazines – will the standard AK mag fit in the receiver or will it all be proprietary stuff?

  • Btr

    Will the 7.62×39 one take ak mags?

  • Lance

    If you want to look to allterative to a 5.56 M-4/M-16 and want a bigger bang asnd not goto a M-14 or M-110. I think the 6.5 ACR is a grat weapon. I can say in my opion that 6.5 grendell is a better round than 5.56mm and could come close to 7.62 NATO w/o the recoil some whips hate.

    The Magpul Masada was demoed with AK style magwells.


    I’ve seen nothing like that for the Bushmaster/Remington ACR. 7.62x39mm will feed from modified M-16 magazines however, like the C-Products magazines.

    AK mags will have to have a different lower as they are a paddle release mag and opposed to a side release style on the M-16 magazine.

    it looks like they removed the x39 interchangeability that was on the Future Weapons video?

  • Let us see if they can pull this off within a reasonable financial window. I’d love one, but money IS an issue for some of us.

    for once, i agree with lance 😉 i cant justify spending that kind of money for a 5.56mm rifle, though i possibly could for one in 6.5 grendel. Yes, the Grendel is superior to the 5.56 and 7.62 NATO and bridges the gap between the two rounds. Im sure the ACR is a wonderful rifle. Bring the price down to 2000 and ill think about it.
