Description
The Arisaka Indexer is a compact hand stop designed specifically for the Geissele Super Modular Rail (SMR) 416. It is typically placed between the index and middle fingers to promote a more forward support hand position without interfering with transitions to kneeling or prone. The Indexer’s wider, flatter profile also functions as a hand stop or barricade stop and acts as a forward limit to help prevent fingers from slipping onto a hot barrel or suppressor.
