Brownells 60 Degree Sight Base File Features The Brownells 60 Degree Sight Base File is built as a true parallel three-square tool with one cutting side and two safe non-cutting sides a design that allows precise widening of dovetail slots without the risk of deepening the slot or marring the untouched edges. This parallel construction gives the gunsmith absolute control over the dovetail angle a level of precision that standard files cannot match. The #2 fine single cut variant is suited to delicate precise final fitting work where a medium double cut file would remove material too aggressively. Maintaining the correct dovetail angle throughout the process preserves the firearm s structural integrity and finished appearance. Measuring 7 inches long and 0.284 inches wide this file is sized for the dovetail slot work most sight base fitting jobs require on rifles shotguns and pistols alike. Made from steel it holds an edge through repeated use across multiple projects in a gunsmithing shop or home workbench. This tool belongs in the kit of anyone who regularly fits or adjusts sight bases offering the exacting control that off-the-shelf files simply cannot provide. For sale at GrabAGun this Brownells sight base file is a precision tool for gunsmiths who demand accuracy in every cut.
