NightForce C542: ATACR 4-16X42 F1, MOAR, ZeroHold

Nightforce : C542

If you need something compact yet powerful, the ATACR 4-16x42 F1 delivers. The fully multi-coated ED glass lenses within are stunning. Adjustments are standard with the Nightforce low profile ZeroHold feature, and available in .1 Mrad (12 Mils per revolution) or .25 MOA (30 MOA per revolution) increments. A capped windage adjustment helps prevent accidental adjustment in the field. The parallax adjustment is marked with approximate numbered distances and is coupled with DigIllum digital reticle illumination. The eyepiece features enhanced engraving, an integrated Power Throw Lever (PTL) and an XtremeSpeed thread for making a fast diopter adjustment. All of these features are paired with intelligent, Nightforce F1, first focal plane, reticles that provide for fast hold-off adjustments and precise ranging calculations. The ATACR 4-16x42 F1 sets a new standard in mid-powered optics.

    Good product, some shortcomings.

    Love the 1st focal plane, glass is outstanding, very rugged (though not tested yet), clicks very precise. Reticle is wonderful, although for my next scope I will switch to mil based system.
    One major complaint--reticle illumination is stupid insane crazy complicated. It works, but there are much better ways of accomplishing this. I know because other manufacturers have done it.
