Overview

Built for sight alignment work on M1 and M1A rifles, these gauges provide a repeatable indexing reference when timing the receiver and barrel components. The front gauge attaches to the gas cylinder on the M1 or the flash suppressor on the M1A, while the rear gauge fits in the stripped rear sight housing to help establish a consistent reference point. Machined aluminum construction and the included illustrated instructions make the set straightforward to use in a shop or bench setting. For armorers and serious rifle owners focused on careful sight setup, this is a purpose-made tool rather than a general-purpose accessory.

  • Rear gauge fits in the stripped rear sight housing.

Considerations & Trade-offs

  • Designed for use with M1 and M1A setups, so it is not a universal timing tool for other rifles.
  • The rear gauge fits in a stripped rear sight housing, which means the sight assembly must be disassembled before use.
  • It is a setup and indexing aid rather than a complete repair or sighting system, so additional tools or adjustment steps may still be needed.
  • Machined aluminum construction with a matte silver finish is practical, but the finish is utilitarian rather than decorative.
