Very nice.

It has to do with the attachment point near the front sight base. The way this rail is designed the front end of the rail is secured a round a "collet" so to speak which has a channel milled out of it to slide into place around the barrel. Unfortunately this channel will only permit barrel movement up or down(only slightly) therefore preventing any "true" free float movement of the barrel.

aside from the channel there, what part of the rail or collet is actually touching the barrel behind the FSB? or is there any part of the actual barrel touching the rail beyond the barrel nut?
