While I agree that people get attached to their purchases, it is possible that on an individual basis that it could be combat ready but maybe not heavily combat tested.
For Mike Kelly who won the Canadian Nationals Level III 3-Gun Match competition using his XCR Rifle than compared to your standard weekend shooter with and XCR is different. If you have taken courses and competed with it extensively it would in my opinion be considered reliable.
I think the "combat-ready" factor is two folded. Years of use by a military in a variety of extreme conditions is one. The SIG/SAN has had this and the XCR has not but only because it is too new. To gain such a reputation requires extensive time and testing. The people at Robarms make good products and my M96 proved it to me with after ten years of hard use. After ten to twenty years we could make an accurate judgment for the XCR.
The second part of "combat-ready" I feel is the individual and their training. No matter hold good the rifle is does not make up for a lack of training and practice. When I pick up my buddy's XCR or my other buddy's Swiss Arms I don't shoot as well as they can with them because I haven't practiced, trained and dry fired it a million times like they have. That said I can match and beat them with my M96 for which I have practiced and trained with and dry fired a million times. There is always the human error factor such as not seating the magazine correctly and having a dud round. If you do not practice and learn how to problem solve your rifle and situation it doesn't matter how great your rifle is. It's now become worthless if in a life and death situation unless you've trained on how to deal with malfunctions.
I've seen too many shooters with all types of firearms, AR15s from all types of brands, SIG Swiss Army, XCR, M96s who did not know how to deal with malfunctions and other problems. For them I would not consider any one of them "combat-ready" because when it does fail (lack of cleaning, malfunction, etc...) they cannot solve the problem.
I definitely agree that the individual is probably more important than the gun.
But buying one gun or another won't solve the problem with the individual, regardless. So of the issues that can be addressed by buying the right gun, we should be asking, "Does the XCR address those issues?"
And I also agree that given enough time, we'll probably have a good idea about whether that's true or not. I just hate watching guys who clearly don't know, announce confidently to everyone else "my gun is ready to go to war and you should feel confident buying one if that's your criteria!"
How many of the guys who say "absolutely, the XCR is as good as anything else out there" have run their gun through a few thousand-round weekends? How many have taken them to training classes and pushed the guns? Those are the conditions that the Colt and DD and Knight ARs seem to dominate in. So before we start saying "it's just as good" let's see just how hard the AR system can be pushed.
ANY rifle will survive a 200 round YEAR. I want to know if it will survive 200 round HOURS on a regular basis.
Not a lot of Canadian shooters do this and I have not seen any XCR owners here stepping up and saying, "here's the XCR I ran at LMS Defense's Carbine 1 and 2, it was awesome as usual and I am taking it to the Oregon Firearms Academy and Blackwater's facility for a few more 1000 round weekends later this year."
What I have seen more of is guys who don't put a thousand rounds a year through their guns saying, "I have 200 rounds through this rifle and it's flawless."
Well that may be, but for me, the real jury is still out, and the deliberations I have been listening to are not overly encouraging for the most part.
In ten years if the XCR has taken over I will be totally happy for both Robinson and for Canadian shooters who will have access to an awesome non-restricted rifle which takes AR mags. But so far I remain skeptical that this will take place.
