X2 - a used 'enhanced' ACR should run around 2k - that's also what I paid for mine. Plus $550 for Dlask to de-restrict it, and it's around the price of a new XCR.
How does the Dlask barrel shoot, I've only seen a couple range reports and they weren't very detailed. I bought a used Herron barrel for mine and had a local verifier do the paperwork to declassify it. I'm still doing load development trying to find something it shoots really well. So far PMC 62gr green tips shoot about 1.5 inch at 100yds and I have a couple handloads that are doing slightly better, nothing under moa yet though.
