I use the Primary Arms 1-6 ACSS gen2. I chose it for the ACSS reticle and price. The ACSS reticle has BDC hashes out 800 yards, calibrated for M855 and M193, and I've found them to be dead on. I've been able to make quick effective hits on target out to 900 yards with it, and it has pretty good glass and daylight bright illumination. All of this in a good quality scope for a tiny fraction of the cost of many of the others out there. It may not be in the same category as the Vortex HD, Leupold Mk8 CQBSS, S&B, etc, but it's a hell of a scope for what you pay.
