Troy Industries Rear Fixed BattleSight Round AR-15/AR-10 Black Hardcoat Anodized

The Troy Industries Rear Fixed BattleSight Round is a permanent, rail-mounted rear iron sight built for AR-15 and AR-10 flat-top platforms. Precision-machined from 6061 aircraft-grade aluminum with stainless steel internals and finished in black hardcoat anodized, this fixed rear sight delivers unflinching durability and a continuous zero through hard use and harsh conditions.

Designed as a direct, no-tools upgrade over the standard A2 rear sight, the Rear Fixed BattleSight Round clamps securely to any standard Picatinny rail and offers a serrated anti-glare ramp that eliminates reflection for a cleaner sight picture. The round aperture pairs with 0.68 MOA windage adjustment for precise zeroing, and the sight installs with no levers or springs to manipulate.

Beyond its primary AR-15 and AR-10 fit, the Rear Fixed BattleSight Round also fits M4 and M16 variants, as well as any other firearm using a flat-top upper receiver or a removable carry handle. Compact and lightweight at just 1.8 oz, it provides a dependable iron-sight backup or a primary aiming solution for any flat-top AR build.
