กล้องติดปืน Vortex รุ่น Diamondback 4-12×40 AO เส้นเล็ง Dead-Hold BDC – ODBK-412B
The Diamondback® — loaded with features! First, the solid one-piece aircraft-grade aluminum alloy construction makes the Diamondback® riflescope virtually indestructible and highly resistant to magnum recoil. Argon purging puts waterproof and fogproof performance on the agenda, and advanced fully multi-coated optics raise an eyebrow when crystal clear, tack-sharp images appear in the crosshairs. Look for all this and more in a riflescope you’d expect to cost quite a bit more-but doesn’t. We can live with that.
- 4-12×40 riflescope is ideal for big game, predator/varmint, muzzleloader, slug shotgun, and long range applications.
- Dead-Hold BDC reticle has a customized design that helps eliminate guesswork on hold-over and windage corrections. Good for any hunting or shooting at varying ranges where estimating hold-over would be a concern.
- Adjustable objective (AO) allows maximum precision on small targets.
