Description
Product Details

The FAST™ ABSOLUTE RISER manufactured by PTS under official Unity Tactical license is the professional solution for elevating optics with standard "absolute co-witness" height (such as EOTech XPS, Leupold LCO and similar).

The 2.26" Philosophy: Heads-Up Posture
The FAST™ series stands out for bringing the height of the line of sight to 2.26 inches (approximately 5.74 cm). This configuration is designed to ensure an ergonomically correct "heads-up" posture. Keeping the head straighter offers immediate tactical advantages:

Faster visual processing of the battlefield.
Reduced neck strain and improved situational awareness.
Ease of aiming while wearing night vision devices, protective masks, headsets, or bulky plate carriers.

Construction and Materials:
The riser is made of high-quality 6000 series aluminum alloy CNC machined, with an anodized finish (available in Black or FDE) that ensures lightness and strength. It installs directly on standard M1913 Picatinny rails via a secure "rail-grabber" clamp. It features the original Unity Tactical markings engraved.
