I just got done building an AR in 6.5 Grendel with the plans on competing in practical rifle field type matches that are shot from 250 to 875 yards. You have to carry your gear from stage to stage during the match. This will be my first entrance into shooting an AR over 250 yards. I've got it set up with a Harris bipod which has it's own sling mount, I used a YHM free float rail so they have a spot for a standard sling swivel on the side of the rail at the end, I would just need to buy the stud that installs into the rail's hole... Or I have a Blue Force Gear rail attachment that I could use. The downside of the Blue Force Gear attachment is that it would require me to run the sling off the side as there is no room on the bottom rail with the bipod mounted.

If I went with the standard sling swivel attachment I could run the sling off the bipod if I wanted it on the bottom. I'm just not sure how much I would use the sling while shooting NM style while standing. I assume if I need to shoot while standing then a bottom mount is a must as the side mount would twist the gun under recoil.

You guys got any input for me?
