acrashb,
Previous posts have made it an issue, by implying that the XCR is on par with SAN rifles, which is the root of the thread "Sig 550 Vs XCR". I (and others) have posted opinons regarding the issue only to have XCR owners come to the XCR's rescue to what I believe are ridiculous levels.
I like XCR's and would love to have one (I don't because I can't have everyting I want) but don't believe for a second that a sample of them would stand up to a sample of some of the other top rated weapons ( I sound like a broken record, HK 416, SCAR, SAN, Colt Canada C8 or SFW).
Throttle monkey 1: Not all AR's are created equal. Some makes of AR 15's will probably fall apart and have more issues that XCR's or others when run really hard. Don't get too excited about some Police Dept's using the XCR or whatever. There are Dept's that use the Ruger Mini 14 and swear it's the greatest gun on earth. Police Dept's choose weapons for some really strange reasons sometimes, you'd be suprised. It's not always because it's the best gun in the World. You'd be hard pressed to find an Operator (Police or Military) that would trade in his/her SG551 or Colt Canada SFW for a Mini 14.
The XCR has a lot going for it and it's cheaper than SAN rifles. So if this is a price issue, buy the XCR some ammo and practice.
There are those here that believe that the SAN rifles are worth the extra money and as a result deliver better performance.
I'm really out, Rich
