There is actual a thread for dis.. but I'm not a big fan of the 3 point slings nor the single points. I use M60 slings on all my AR's and on my PTR91. I did add a small loop of 550 cord and HK style metal snap hooks (DIY tactical has them for $1.25ea) so they are quick detatch.

Marpat is working on a home made 3 point sling that will be interesting if he ever gets it done. Then again he's finally gotten his own AR and now has motivation to knock it out finally.
