1. Wheeler's Delta Series Pic Rail Riser is designed for precise optic and accessory mounting above a Picatinny rail.
2. The riser aids in achieving the perfect co-witness alignment of scopes and night vision devices.
3. Multi-Height Pic Rails offer versatility for maintaining zero point accuracy in day/night shooting systems.

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.
