The Sinclair International F-Class Rest Feet are designed to prevent rest feet from sinking into soft ground during shooting.
These rest feet are made from solid stainless steel, feature 3/8x16 threads, and are sold in a pack of three.
An additional purchase of the 749-013-900 leg is necessary for full compatibility, except for those with Sinclair Heavy Varmit Rests which already include the standard rear leg.
