Overview

A 3-9x40mm rifle scope with the Buckmasters bullet drop compensation reticle, built on a 1 inch tube and calibrated with holdover dots for shots out to 500 yards.

  • 3-9x40mm variable magnification
  • Buckmasters BDC reticle
  • Holdover dots calibrated to 500 yards
  • 1 inch tube, black finish

Who it's for

Suits hunters and shooters who want a clear, budget-friendly scope with BDC holdover for shots at typical hunting distances. Less ideal for someone who wants rings included in the box, since those are sold separately.

What buyers say

From Amazon customer reviews.

Reviewers who mounted this on rifles for hunting, including kids' first deer rifles, repeatedly say it rivals scopes costing much more, several name Vortex and Nikon directly, and it held zero even after a reviewer intentionally dropped it on gravel twice. The one consistent gap noted is that scope rings aren't included, so buyers need to order a 1 inch set separately.

Strengths and trade-offs

Drawn from this product's published specifications.

What to check first
  • Scope rings not included, sized to 1 inch tube
  • 3-9x magnification suits mid-range shots, not long distance
