My XCR is an early rifle, sub 200 serial number. I have had lots of issues with RA breaking pro,uses and commitments, including Alex himself breaking verbal and emailed commitments. Support was much improved for a while when a certain young lady was handling it but generally my opinion is that RobArms shouldn't be trusted. Buy from a dealer and if they have it in stock, otherwise call Nate, Kermit or whoever you find and wait until they have he item in stock. My XcR has thre caliber kits and numerous spares built up,over the years but only one rifle. In that time my plans for getting them for ,y wife and kids switched to other platforms that had better support, customer relations and frankly better quality and timely delivery.
Alex provides lots of excuses and while he is a pretty smart designer, taking ideas of other rifles and amalgamating them into a single product, he sucks at running a business. Is the XCR good, yes, but frankly I can do everything it does with other rifles now.
i like my rifle and will keep it, but I won't buy any more. unfortunately the best thing about he XCR is not the rifle, it is this community.
