After approximately a million years, Bushmaster has shipped the DMR variant of the ACR to US distributors. Not sure but I think they've only shipped these to Canada before, making this is the first US appearance.
Looks like we get the Geissele trigger, an 18.5" barrel, AAC 51T Blackout flash hider, Magpul PRS2 via an ACR stock adapter, and the enhanced handguard. Gas system appears to be of the same length.

They've been teasing photos on their Facebook page for a few weeks, so I've been wondering when they would hit.
Available here (I have no interest in this site aside from purchasing my coyote ACR from them last year) for $1913:

Price doesn't seem too bad compared to the regular ACR at around $1600 considering what they're including with this version; I put at least $200 towards mine when I replaced the trigger and A2 flash hider.
Does this mean 2017 might finally be the year for new barrels? Maybe someone can drag a Bushmington rep into a closet at SHOT and press them for details.
