i boght the KT sling, but since i shoot long guns left handed, and want the sliing to be ambi, that ain't gonna work. i need to put it on the trading post.
i've seen some using AR clamp on single point sling adapters, looks like they have potential if you ant a simgle point sling.
a GG&G "Sling Thing" should work in the sling slot on the buttstock
and this http://www.gggaz.com/quick-detach-sling-thing-for-dovetails.html
would mount to the rails on the sides of the HG, or the one above would bolt thru the side of the original handguard. there are also other flavors of rail mount QDs that are less expensive.
there are also non-QD versions of the Sling Thing both for the buttstpck and rails, but i think i'd prefer the QDs.
not exactly cheap, but should be solid.
