I have the Outlander on my Bergara B14. No complaints about it. Pretty lightweight, good feel and it dropped right in. I did put a makeshift cheek riser on it as the comb height is a bit low for me and there is no cheek piece. I don't think it made the rifle any more accurate but it didn't hurt it by any means. It has always shot at least MOA.
I've got an outlander on a 700 LA. It's been beat against the rocks on elk and goat hunts, packed in on mules multiple times, always rigged with a bipod. Never had an issue.
I have one, no problems breaking or cracking yet, but the barrel channel isn't exactly even side to side. It's still free-floated, so I haven't messed with it.
