It's funny the way single point slings have gotten a bad name. To each his own. I have a single point on all my AR's. I wear it with my left arm through the sling (I'm a rightie.)

Allows me to hang the weapon on my left side/access to the handgun/quick recovery back to the rifle. I've never hit myself in the nether area nor have I whacked my knees (common complaints of the single sling detractors.). Granted, I wouldn't want to take a long hike with the rifle in that position, but I'm don't fancy a long hike with any tactical sling if you're not using one hand to take up some of the weight.

I was using a Blackhawk nylon strap on the 15-22, but I've gone to an aluminum mount with ambi rings that slips over the tube. I can't think of the manufacturer at the moment, but if I get a chance tomorrow I'll post the name and a pic.
