I am a self-defense, SHTF type shooter. In looking at low power, variable optics, 1-6X or 1-8X, somehow this video popped up. This is Barry Dueck, former USMC, who says at 1:06 minutes into this video, he can hit moving targets better with his offset A2 style irons than the big optic.

For me, I am far more apt to encounter some robbery or home invasion at close quarters than lead a target in a scope with hash marks. Most likely they will have pistols. Guys with pistols run and gun, so they are always moving.

So what is best for close quarters, 75 yards in in, on a moving target? Irons, Red Dot, Variable Powered Optic? Vote and say why.
