What's this 'Feather' thing? I've never heard of one, and probably never seen one. (my google is tired, humor me here)
I do have a CX4, and like it a lot! I wish the trigger were nicer, but it should break in a bit (only have about 200 rounds through it... 0 problems so far!). I'm gonna get the top rail and the side rails (already have one side rail), mount a sling adapter on the left, and a weaponlight on the right, then get a S.P.O.T. Mk III for the top. Maybe later on, thread the barrel and suppress it. It's very high quality. Just handling one will give you that impression. Take it down, and that impression will be reinforced.
If CX4 is in your budget, I'd recommend it, and I'd say with confidence that unless you're just weird, you'll be completely satisfied with it.
