Sentry Strap by NeoMag
The Sentry Strap, by NeoMag, is their solution to sling staging. It utilizes two powerful magnets to hold your sling fast to your rifle. Deployment is simple. Just grab your sling, give it a tug and the Sentry Strap breaks away and releases your sling. Fast and easy. That's the way we like it.
The minimum size the Sentry Strap will fit is roughly 1" (a buffer tube). The maximum circumference is 8" (2.6 Max Diameter). The Sentry Strap is secured with Velcro. The sling catch is secured with magnets and will fit anything from padded slings to webbing straps.
