ELEVATION ADJUSTMENT
- ~1.6 MOA (1.886"/100m) per click with a 14.5" sight radius
- ~1.2 MOA (1.367"/100m) per click with a 20" sight radius
*NOTE: Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed fore end on the same plane as the receiver rail. Because of this the sight is also not compatible with MOE Hand Guards.
