FYI, with the location of the safety on the Belgian T-Bolt, one needs to mount their scope with either medium or high rings to have room for your thumb to easily access it. I initially had low rings on mine as my scope is a Clearidge 3-9X32. That didn't leave enough room for my thumb to quickly and easily flick the safety off. For my skinny thumbs a set of medium tip-off rings works well. Those with chubby thumbs might need high rings.
