Operating in high-stress tactical environments or wearing heavy protective gear often makes acquiring a traditional optic sight picture uncomfortable and slow, forcing shooters to unnatural neck strain and cramped head positions.
The Unity Tactical FAST™ Optic Riser is engineered to solve this exact ergonomic bottleneck. By elevating most lower 1/3 co-witness rail-mounted sights (such as the EOTech® EXPS Series) to a 2.26″ optical centerline, it provides a much faster and more natural "heads-up" shooting posture. This increased height significantly improves target acquisition speed while accommodating bulky equipment like electronic comms headsets, gas masks, and night vision devices for effective passive aiming.
Key Features
- 2.26″ Optical Centerline: Raises optics higher than standard mounts to allow a head-up posture, critical for wearing tactical gear and night vision equipment.
- Rugged 7075-T6 Aluminum: Precision-machined from high-grade 7075-T6 aerospace aluminum for exceptional durability and impact resistance.
- Mil-Spec Hardcoat Anodized: Finished with a Type III hardcoat anodized surface to resist field wear, corrosion, and harsh environments.
- Versatile Clamping Options: Ships standard with a two cross-bolt rail clamp and is fully compatible with the optional FAST™ QD Lever.
- Ecosystem Integration: Designed to pair seamlessly with FAST™ FTC magnifier mounts for a cohesive modular sighting system.
