Variable magnification riflescope

The BARSKA AC10042 offers a 4-16x zoom range with a 50 mm objective lens and adjustable objective for parallax correction. Multi-coated optics and a 30/30 reticle support precise aiming at extended distances. The one-inch tube provides 3.5 inch eye relief and 1/8 MOA click adjustments for windage and elevation.

Suited for varmint and long-range target shooting

Hunters engaging small game at distance and shooters needing fine reticle adjustments will benefit from the adjustable parallax and high magnification. Buyers who require illuminated reticles for low-light conditions or a first-focal-plane reticle for holdovers at any power should consider other models.

4-16x magnification with 50 mm objective

The zoom range and large objective determine light gathering and detail resolution for distant targets. Exit pupil varies from 12.5 mm at 4x to 3.1 mm at 16x, while field of view spans 16 ft at 100 yds on low power and 5.7 ft at 20x equivalent. These optical limits define whether the scope matches the intended engagement distances.

Questions about this item

How do I mount the 1-inch tube scope and set the 3.5-inch eye relief without getting scope bite?

Use 1-inch rings matched to your rail, then slide the scope until the full 12.5 mm exit pupil at 4x is visible with your head in a natural shooting position; tighten rings in a cross pattern to lock that distance.

What upkeep does the multi-coated 50 mm objective and nitrogen-purged tube need over time?

Wipe lenses with a microfiber cloth and lens solution only; the sealed tube is waterproof and fogproof, so no internal cleaning or gas refill is required.

At what magnification does the 1/8 MOA click value make windage dialing too slow for rapid follow-up shots?

Above roughly 10x the finer 1/8 MOA increments demand many clicks for large corrections, so shooters often dial at lower power then zoom to 16x for final aim.
