I have a Knight's 1" Stock Extension w/ Sling Swivel Mount that has a push-button swivel that allows ambidextrous sling mounting. This tactical position is a great mount point for a 3-point sling. Anyhow, I had it on my Shorty stock to give me another 1" of shoulder spacing. It comes complete with the buffer extension, extra long machined screw and actual sling mount. This will not work on a regular 4 or 6 position collapsable stock. I accept paypal or M.O. If in the Portland, OR area, I may be able to meet you.
Trades? I'm only looking for some brand new black teflon DPMS mags or a Tango Down Foregrip.
