The Unity Tactical FAST Accessory Riser is an ultra-compact, precision-machined rail block built to elevate tactical electronics by exactly 0.725 inches. Crafted from high-strength 7075-T6 aerospace aluminum and finished in an anodized Flat Dark Earth hardcoat, it securely clamps onto M1913 Picatinny slots via a heavy-duty two-bolt mount. The riser is specially optimized to bring block-style red dots, night vision lasers, and thermal imaging systems up to an ergonomic 2.26-inch optical centerline. This raised configuration establishes a natural, heads-up shooting posture that dramatically accelerates reticle tracking while wearing gas masks, helmets, or communication headsets. Spanning only three physical rail slots to maximize open handguard estate, the design integrates a built-in pass-through slot underneath to keep messy remote switch cables safely tucked away.
