I really like my XCR but:
-It does not break open far enough... I modified my upper so it would open all the way. It is easy to do and should have been done in the factory... That way, one can access the firing mechanism without removing the front pin (which is difficult). Furthermore, removing and reassembling the bolt assembly is easier when fully opened.
-The front pin should be captive and easilly removed without the small, easilly lost, difficult/impossible to remove without a pointy tool, clip... Loose that clip and the rifle will soon be out of commission. And you NEED to remove the front pin to access the firing machanism unless you modify the upper so it opens all the way...
-There should be a more slender barrel option... Fluting is expensive while turning a lighter profile barrel is easy. I don't care much about heat problems with 5 round mags in semi-auto. The way it is now, the barrel contour is that of a fairly heavy .308... I don't need an HBAR or heavy varmint barrel on a .223 for general field use. If Robinson does not come up with a slim barrel, I'll have to have mine turned. That will surely solve the front-heavy balance and poor offhand caracteristics.
My rifle is an older version but the new ones have better triggers and ambi-controls. I heard rumors of canadian made stock adaptors that would allow the use of AR colapsible stocks... That would be good news indeed. My rifle has an original adaptor and I like it a lot.
The XCR is a well made, accurate rifle. It has some quirks and not everyone likes it... But you know, I owned a Classic Green and it did not like it... Well made but heavy as hell, not very good ergonomics with the controls, mickey mouse bipod, no rails, expensive, unavaillable mags, expensive... My advice is to try many rifles and pick the one you like. I love the AR platform for many reasons but it is restricted and you can't do anything with it in Canada.
