SIG Sauer SIERRA3BDX Riflescope

The BDX system pairs your riflescope with a compatible SIG Sauer laser rangefinder via Bluetooth. It automatically calculates your ballistic holdover based on your specific load and environmental conditions, then illuminates the exact holdover dot on your reticle so you don't have to manually adjust your turrets.

You don't need the app for every shot, but you do need it initially to program your specific ballistic profile into the scope. Once your load data is synced, the scope functions seamlessly with your rangefinder in the field.

The SIERRA3BDX features an adjustable illuminated holdover dot that is designed to stand out against dark backgrounds. Combined with the 30mm tube, which allows for greater light transmission, it provides a clear aiming point during the critical dawn and dusk hours.

Yes, it is built to handle harsh environments. It features an IPX-7 waterproof rating, meaning it can withstand submersion, and the internal construction is fogproof to ensure your view remains clear even during rapid temperature changes.

Yes, the reticle remains visible without power. However, you will lose the digital holdover dot functionality, so you will need to rely on the standard reticle markings for your aiming points until you replace the battery.
