The Holosun Technologies ARO-RD2 ARO Enclosed Red Dot Sight is a compact 1x optic designed for fast, reliable target acquisition. As an upgrade to Holosun’s popular 403 and 503 series, the ARO features a rugged 22mm housing that integrates cleanly with compatible magnifiers while maintaining a streamlined profile. Its crisp 2 MOA red dot reticle provides a precise aiming point for close- and medium-range applications without obscuring the target.
The ARO-RD2 includes a 1.63-inch lower 1/3 co-witness pedestal mount, allowing the optic to align naturally with many standard iron sight setups. The enclosed design helps protect the emitter and internal components from environmental exposure, making this red dot sight a practical choice for demanding range, duty, hunting, and defensive applications. The black finish provides a low-profile appearance and complements a wide range of firearm configurations.
Built around Holosun’s ARO platform, the Holosun Technologies ARO-RD2 combines straightforward operation with magnifier compatibility and a clear red dot aiming solution. Its 2 MOA reticle balances speed and precision, while the 1x optical power preserves natural sight awareness and both-eyes-open shooting capability. This model is configured with a red dot-only reticle for users who prefer a simple, uncluttered aiming interface.
