SHOT Show 2020: SIG Sauer Sierra3BDX 2.5X-8X-32mm Riflescope

posted on January 26, 2020

For 2020, SIG Sauer has partnered with Mission Crossbows to develop the Sierra3BDX 2.5x-8x-32mm ultralight riflescope that is the perfect size, weight and magnification range for crossbow configurations, making it possible to reach out well beyond 100 yards, and engage targets with extreme precision.

The Sierra3BDX 2.5x-8x-32mm scope is compact and lightweight so it won’t alter the balance of a horizontal bow. It is designed to be used with the SIG Sauer Kilo BDX rangefinder, which is connected to the scope with Bluetooth, through the free SIG BDX app for Android and iOS systems, where the user develops a ballistic profile for their specific crossbows.

Simply range a target and the information is immediately sent to the scope, illuminating the correct reticle point for an exact hold. You can set up several profiles on the app to use with different crossbows. The scope has .25 MOA adjustment, offers second focal plane magnification and is built on a 30mm tube.

Technical Specifications:
• Weight: 19.4 ozs.
• Focal Plane: Second
• Magnification Increments: 2.5x-8x
• Adjustment Increments: .25 MOA
• Reticle: BDX-R1
• Objective Lens Diameter: 30mm
• Tube Diameter: 30mm
• Illumination: Yes
• Battery: CR2032

The SIERRA3BDX 2.5X-8X-32mm has an MSRP of $519.99. For more information, visit
