The Forster 6-48 Bushing Set (brand part no. UF1000-UB0648) is a matched set of guide bushings sized around the 6-48 screw thread, one of the more common thread sizes found on sight bases, scope mounts, and small firearm hardware. Forster Products builds the set so the correct drill and tap bushings are matched to each other for 6-48 work, keeping both operations on-axis instead of guessing at compatible bushings from separate sets. A wandering bit on a 6-48 hole often means a misaligned sight or mount later, so the guide matters as much as the tap itself. It’s a natural fit alongside the rest of our gunsmithing tools and gunsmith supplies for sight and mount installation work.
