The fluting on my two FV-SRs and TR are so light as to nothing more than decorative. Unless you like the 'look' I wouldn't even use that as a factor.

I DO like the bolt knob on my SRs and TR much better than the standard bolt knob on my FSS.

It may be luck of the draw, but my first FV-SR is the 'most accurate' (more consistant groups may be a better way of putting it) of all of my MKIIs.

Will you be using a can?
