Troy Rear Fixed BattleSight AR-15 AR-10 Picatinny Hardcoat Anodized

The Troy Ind SSIGFRSROBT00 Rear Fixed BattleSight Round Black Hardcoat Anodized for AR-15/AR-10 delivers rock-solid stability and dead-on accuracy as a permanent rail-mounted alternative to a standard A2 rear sight, with a serrated ramp to reduce glare and a design that provides constant access to fixed sights that continuously hold their zero. Machined from hardened aircraft aluminum with stainless steel components and finished in MIL-SPEC hardcoat anodizing, this sight offers unflinching durability and peace of mind for long-range confidence on the range or in the field. It fits all M4/M16/AR-15/AR-10 variants with flat top receivers or removable carry handles and is intended to work on same-plane rail systems only, ensuring the front sight must be mounted at the same height plane as the rear sight and that railed gas blocks higher or lower than the receiver will not zero properly. The Troy Rear Fixed Rail Sight is a permanent, rugged solution that retains its zero and simplifies optics alignment, enabling repeatable, fast target acquisition on AR-pattern platforms while maintaining clean integration on Picatinny rails for versatile mounting options.
