Troy Industries M4 Folding BattleSights Set (Front M4 + Rear DOA Dioptic)
This set includes a Troy Front Folding BattleSight (M4) and a Troy Rear Folding BattleSight (Di-Optic Aperture/DOA). Both sights fold out of the way at the push of a button and lock upright via Troy’s stainless steel cross-locking system.
Built from hardened aircraft aluminum with stainless steel components and a mil-spec hardcoat anodized finish, these sights are designed for same-plane rail systems and provide .50 MOA click adjustments.
