Overview

This tooling is intended for correctly modifying military safety shrouds so they can accept two-position safeties from Wisner’s Inc. It is a Brownells item built around a blue steel combination arbor with a 1/2" shank, and it accepts 1/2" through 1" arbor slotting saws. The listed components include a 30-tooth HSS slotting saw and an HSS Woodruff cutter, with the parts sold separately. For hunters or gunsmiths working on compatible safety conversions, it provides the specialized setup needed for that specific task rather than a general-purpose shop solution.

Considerations & Trade-offs

  • Designed for a specific modification task rather than general shop use, so it has limited value outside installing two-position safeties on military safety shrouds.
  • The listing notes that items are sold separately, so the combination arbor may not be a complete setup by itself.
  • Tooling is specified for 1/2" shank arbor slotting saws and related cutters, which means compatibility is defined and not universal.
  • The description is focused on the modification function, so buyers should expect a specialized tool rather than a multi-purpose installation kit.
