Green Mountain's web site has the 17 inch blue and stainless Ruger 10-22 MAGNUM barrels on a close out special for $74 blued and $84 stainless. Anyone used/have one of these on the 10/22 Mag Ruger?? I'm sure the 20" is the big seller - does the 3" make that big a difference (I'm sure it will be louder) in accuracy? I'm thinking about ordering one.
