Ditched the B-square adjustable mounts and going down the AJP and sportsmatch one piece. I need the AJP for the slope to save shimming as rob describes, and because the Deben 10-50 is very close to the breech. Plus i've got so used to 'head up' that it's too cramped behind her without raising the scope.
So far with a test rail, she's holding. Still working out the correct slope for the height of rail and scope.
