Barska 10-40x50mm rifle scope

This Barska AC10366 riflescope delivers variable magnification from 10 to 40 times with a 50mm objective lens. It is built for shooters who engage varmint or long-range targets and need precise adjustment controls. The 30mm monotube chassis is shockproof and nitrogen purged for waterproof and fogproof reliability in extreme temperatures.

Upgrade from fixed-power

The variable zoom ring and lockable target-style turrets replace simpler scopes that lack side parallax adjustment or fast-focus eyepieces. The jump is worth it when shooting distances change frequently and repeatable windage or elevation clicks are required. Buyers who need a compact low-power optic for close-quarters use will find the magnification range excessive.

Sustained performance under recoil and weather

The high-impact rated monotube and o-ring seals maintain zero and optical clarity after repeated heavy-recoil sessions. Fully multi-coated lenses preserve contrast during extended glassing in heat or cold without internal fogging. The included sunshade reduces glare during all-day observation, while the see-through rings allow backup iron-sight use if the primary optic fails.

Questions about this item

What size rings are included for mounting the scope?

The package includes a set of 5/8-inch high see-through rings for mounting the scope to the rifle.

How do I adjust the focus and magnification on this scope?

Focus is set using the fast-focus eyepiece, while magnification is changed via the zoom ring; a common error is adjusting magnification before the reticle is sharply focused.

What protects the optics from fogging and water over time?

The 30mm monotube is CO2 dry nitrogen purged and O-ring sealed to provide waterproof and fogproof protection for the life of the scope.
