I've been using the GroveTech Mountaineer or the Uncle Mike's Mountain Sling. They are about the same with sewed in swivels and "textured" inner layer but the GroveTech is made in the USA and I believe the UM's is now made in China.

UM bottom is a metal buckle (this one isn't the Mountain Sling) and the GroveTech is nylon
Camo GroveTech of 7-KS/.350 Mag. is tucked in behind the gun but you can see a little of the pattern...
GT with the gripper inner layer...
