Cabin fever, needed something to do so figured I put this up. This is a design I'd put together with readily available materials. Uses a 1" bar so it can be hung with standard rings. 2" Angle aluminum. Cut down furniture bolt + handle. Key to making it work is the mount hole in the cradle needs to pressure fit the flat edge of the Magnetospeed against the inside of the cradle. The cradle slot needs to pressure fit against the rear of the fixed bracket. The bar needs to be cut and brazed perpendicular to the bracket. Pay attention to the distances of the brazed mount, too far in and you interfere with the barrel too far out and you won't have enough travel to properly set distance. Also, watch the cradle distance behind the Magnetospeed, too close and you can't plug it in when mounted, and may loose clearance for an allen if the bolt spins (see rubber washers for added friction on this connection point.) As for final fit and finish, I'm a function over form guy so don't care what it looks like and only use it for load workups.
