Additional handwheels make switching tops on a Sinclair rest a snap. Many shooters like to have two handwheels if they are using a B/R top in competition and an All Purpose top for sighting in hunting rifles or varmint shooting. Our stainless steel handwheel fits all Sinclair rest post except competition rest. Only fits the lite weight rest, does not fit Gen II rest.
