@drewheyman: Max effective range for a 12 gauge 2 3/4" slug is about 100 yards, With a sabot it jumps up to around 125 yards. But even the top of the line sabot has about 3' of drop at those ranges and this weapons sighting system is a scaled up version of that found on the M-16.

Also I just found another article claiming it has an effective range of 200m, not 150m.

I call utter PR bullshit on this.
