Tipton 360 vise issue - Tipton Best Gun Vise 360 Multi Use

At first I was impressed with the vise but once I started using it for different tasks on my AR I found that the ball adjustment knob would not tighten down enough to keep the rifle in the vise from moving. That could be a problem if you’re trying to torque or break torque on your rifle. Also found that if you have a long barrel rifle and you have it clamped down by the magazine and working near the front of the rifle it tends to tilt the rifle because theres not enough pressure on the ball adjustment
