The Reptilia ROF-90 34mm Black 7075-T6 Aluminum is a drop-in upgrade designed for the Reptilia AUS Mount or Geissele Super Precision 34mm magnified optic mounts, offering a seamless integration onto AR-15 platforms with a rugged anodized finish. This Picatinny-based ROF-90 enables close-in target engagement and passive aiming with night vision by placing an Aimpoint ACRO or Steiner MPS at 90 (12:00) to provide a dedicated, compact red-dot option alongside a magnified optic, while preserving full compatibility with subsonic ammunition such as 300 AAC Blackout when zeroed for subsonic use and allocated to the close-range sight, enabling versatile ammunition handling without sacrificing magnified performance for longer-range shots. Crafted from durable 7075-T6 aluminum, the ROF-90 delivers reliable strength and light weight, maintaining precise alignment and repeatable zero across varying field conditions. This mounting solution enhances versatility for tactical and hunting applications by combining the benefits of a high-quality 34mm optic platform with a fast, intuitive close-range capability, making it an ideal enhancement for AR-15 setups requiring integrated, NV-friendly close-quarters optics.
