Re: Zero Stop Washers
Measure the OD you need to fit inside the turret cap and go to Lowes or Home Depot and buy several white nylon washers with a close OD (smaller, not bigger), then drill the hole in the center to fit your stem. Stack them up until you get close to where you want and then sand the thickness down to get them perfect. Lay a piece of sandpaper on a flat surface and sand the washer in a figure 8 pattern to reduce the thickness.
I just wanted mine so I could not go a complete turn too far, and have mine adjusted so I have 5-7 MOA or so under.
It's been a long time, and way be remembering wrong, but I think I just stacked up some rubber 0-Rings on my Leupys w/ M1 knobs.
