I went from the olds style to MS2 with ASAP plate so I have never used a quick detach system. But I see the CTR stocks and a lot of other accesories have the the detach points. I am interested in trying it but not sure what I need? I want an FDE sling that can be used in single or 2 point configuration, I will have a CTR stock but may go with the setup that slides on the buffer tube, so I will need a from contact point that will attach to MOE handguards. What do I need? Best sling for the money? Thanks.
