I gave them a ring up there in Sidney as soon as I saw their GI listing.
From what I was told over the phone, all the calibers have the same exterior
barrel profile. Therefore, the larger the caliber the lighter the barrels. This
is all heresay as I haven't handled any of them yet. The rifles are supposed
to make it down to Fut Wutt sometime after the first of the year. You'll be able
to dust them for my prints soon after.
