Look at what a proper military sniper uses on a rifle - it's not a Nightforce. I spent a good few years in the military, and we used German optics every time. Neither the US M25 or M40 sniper set-up, nor the British L96, nor the German PSG-1 uses Jap optics. In fact, I believe the Yanks have now opted for the Leupold Mk 4, having ditched US Optics.
You cannot compare a police marksman with a military sniper.
