Now having used my Atlas for a while, unlike the tilting feature on the Harris, the Atlas can be set on a tension level that once broken in that doesn't require consistent adjustment. Also, ran into a mount produced by Seekins that is a superb mount for rifle stocks. It is an integrated sling swivel and is supplied to fit a two hoke configuration for McMillan, HS, or B&C .
