TruGlo Buckline Black 3-9x40 BDC Rifle Scope

The TruGlo Buckline 3-9x40 BDC Rifle Scope combines a common 3-9x magnification range with a 40 mm objective and TruGlo’s Duplex BDC reticle. The reticle adds holdover reference points while retaining a familiar central aiming picture, giving the shooter more information than a plain duplex when distance changes. Variable power lets the same optic cover wider close-range views and more detailed aiming at the upper end.

Windage and elevation move in 1/4 MOA clicks for predictable sight-in adjustments, and the fully coated lenses help maintain image clarity through the magnification range. TruGlo includes Weaver-style scope rings so the optic can be installed on a compatible base without purchasing rings separately. This 40 mm version keeps the objective more compact than the 50 mm Buckline while preserving the same 3-9x power range.

The 3-9x40 Buckline is a traditional hunting configuration that balances a common magnification range with a moderate objective size. Its BDC dot reticle and included rings keep the package focused on practical field use without unnecessary controls.
