Unity Tactical FAST Accessory Riser 0.725" Picatinny Black - FST-RLB

Unity Tactical FAST Accessory Riser 0725 Height Fits Picatinny Anodized Black FST RLB UPC 810007883021

Product Description

The Unity Tactical® FAST™ Accessory Riser (SKU: FST-RLB / UPC: 810007883021) is an elite tactical rail enhancement designed to elevate electro-optics and rail-mounted accessories by 0.725 inches, establishing an optimal 2.26-inch optical centerline when paired with native lower-1/3 cowitness height optics. Developed for military, law enforcement, and professional carbine shooters, the FAST platform promotes an upright, heads-up posture that drastically improves target acquisition speeds, maintains environmental peripheral awareness, and facilitates natural, unencumbered sight pictures while operating with plate carriers, ballistic helmets, communication headsets, and night vision systems.

Precision CNC-machined from high-strength billet 7075-T6 aluminum, the FAST Accessory Riser provides unmatched mechanical durability and zero retention under severe weapon recoil and hard tactical deployment. The mount is treated with an abrasion-resistant MIL-A-8625 Type III Class 2 hardcoat anodized matte black finish that suppresses glare and resists corrosive bore solvents, extreme field temperatures, and abrasive debris. A specialized pass-through channel is CNC-machined along the underside of the riser, permitting streamlined, snag-free routing for tape switch leads and remote pressure pad cables directly underneath the mounted unit.

Featuring a rugged two-cross-bolt rail grabber clamping system, the FAST Accessory Riser locks rock-solid onto any standard MIL-STD-1913 Picatinny top rail without shifting or losing zero. Beyond elevating red dot sights like the SIG Romeo8T or Leupold LCO, it serves as the premier riser solution for rail-mounted aiming lasers (including PEQ-15, NGAL, and DBAL units), elevating the laser emitter plane to clear forward-mounted weaponlights, switches, and folded backup iron sights while preserving unobstructed hand placement on slim modern handguards.

*Armorer Bench Notes & Real-World Staging Guidance:*

Fitment Matrix: Mounts to any standard MIL-STD-1913 Picatinny rail interface. CRITICAL WARNING: Incompatible with Weaver-only rails lacking standardized MIL-STD slot dimensions. Recommended cross-bolt fastener torque is 35 in-lbs using a calibrated T25 Torx driver. Over-torquing may strip receiver clamp threads or damage polymer upper rail slots. Never apply permanent red threadlocker; use a semi-permanent medium-strength blue threadlocker (e.g., Loctite 242 or Vibra-TITE VC-3) to secure clamp hardware.

1. Confirm the host carbine or rifle is completely clear, magazine removed, and chamber visually and physically verified empty before securing the upper receiver in an armorer bench vise.
2. Thoroughly clean and degrease the host MIL-STD-1913 Picatinny rail surface and the underside clamp geometry of the FAST riser with isopropyl alcohol.
3. If utilizing remote pressure switch cables, route the wires neatly through the integrated underside cable channel before setting the mount onto the receiver rail.
4. Seat the FAST Accessory Riser firmly into the desired rail slots, pushing forward toward the muzzle to seat the cross-bolts against the front rail recoil surfaces.
5. Evenly alternate tightening the dual T25 Torx cross-bolts to 35 in-lbs using a precision torque wrench, mount your primary optic or laser unit to the top rail, and conduct live-fire zero confirmation.

Key Features

• 0.725" Optical Elevation: Elevates native lower-1/3 cowitness optics (e.g., SIG Romeo8T, Leupold LCO) to an upright 2.26" optical centerline for rapid target transitions and passive NVG aiming.
• Billet 7075-T6 Aluminum: Machined from solid aerospace-grade aluminum to deliver unmatched structural rigidity, lightweight handling, and return-to-zero reliability.
• MIL-A-8625 Type III Hardcoat Anodized: Durable matte black finish eliminates reflective glare and resists chemical solvents, heat, and harsh abrasion.
• Underside Cable Routing Channel: Integrated recess enables clean, snag-free wire management for weaponlight and laser pressure switch leads directly beneath the mount.
• Dual Cross-Bolt Grabber Clamp: Heavy-duty dual steel cross-bolts ensure rigid clamping force across all MIL-STD-1913 Picatinny rails under aggressive firing schedules.
• Optimized Laser Clearance: Elevates IR/visible laser systems to clear bulky support-hand grips, tape switches, and forward accessories on compact rail systems.
