In response to bigger night vision and Thermal sights, as well as larger Laser Pointers, Badger designed the Offset EFR rail to accommodate the newer range of electro optic devices. The mount lowers the laser device 1.1" and adds only .1" to the width. Machined from 6061 Alloy and Mil Spec Type III Hardcoat Anodized. This part attaches to the Badger EFR front rail structure.
