1. Wheeler's Delta Series Pic Rail Riser is designed for precise optic and accessory mounting on Picatinny rails.
2. The riser helps in achieving the perfect co-witness alignment of scopes and forward-mounted Night Vision Devices.
3. It addresses the challenge of calculating optic height above a receiver rail by offering Multi-Height Pic Rails for various applications.

Wheeler® understands the need for precision in today’s world of advanced shooting systems. Calculating total optic height above a receiver rail is difficult due to varying specifications from a variety of ring manufacturers. The necessity to mount optics and accessories at a precise height above a Picatinny rail led us to the development of Multi-Height Pic Rails. Being able to select a riser that fits the particular application allows for the perfect co-witness alignment of a scope and forward mounted Night Vision Devise (NVD). Proper alignment of the scope with the NVD is critical in maintaining the same zero point with a day/night system.
