I posted this on a different thread but thought new post might get seen by others in similar situation. I was using a good bit of length on my rest front screw feet to get my rig level and knew there had to be a better way (insert infomercial here). After trying several different things figured out hockey pucks are exactly 1 inch thick which works perfectly for me. The spikes in the feet do dig into the rubber a little bit but I painted where they sit for repeatability. Banda bing bada boom elevated rest.
