I'm thinking of adding a sling to my m&p 15or. And had questions on the attachment locations and sling basics. From my reading I think I want a basic 2-pt sling but having one that can be both a 1 or 2 point may be worthwhile.
I think for the front ill be ok going with a QD swivel attached to the bottom of the gas block.
I get confused on the rear attachment point though. For basic 2 point slings I've seen attachments on the buffer tube, the bottom of the stock or attached or wrapped into slots in the stock itself. Will any of those work for a 1pt sling as well? Or does it have to be a swivel attached to the buffer?
Thoughts or advice appreciated.
