Power Custom Series II Stoning Fixture .154" Adapter for AR-15/M16

Eliminates the guesswork and provides an accurate, repeatable method to achieve a crisp, clean-breaking trigger pull.

How it works

Individual, easy-to-change adapters attach to a precision-ground indexing elevator column and clamp the hammer in the right position for correct stoning with the specially ground Series II India Stone.

Adjustable design lets you change hammer angle to meet the shooter’s needs.

Series II India Stone required for use. Purchase separately.
