Description

The SIG Sauer SIERRA6BDX 3-18x44mm Rifle Scope is a second focal plane scope with the BDX-R2 digital ballistic reticle, adjustable parallax, 0.25 MOA clicks and a 30 mm tube, powered by two CR2032 cells.

BDX is the digital part: paired over Bluetooth with a SIG BDX rangefinder, the reticle illuminates a holdover dot at the correct elevation for the ranged distance and your load. The 3-18x range and adjustable parallax make this the mid-size model, suited to stalking and target work at longer distances than the 2-12x40.

How It Compares

Want less magnification and less weight? The SIERRA6BDX 2-12x40 is 21.4 oz with fixed parallax. Want more reach? The SIERRA6BDX 5-30x56 uses a 34 mm tube. Want the same BDX system with an AR mount included? The BRAVO6T-BDX 3-18x44 ships with an ALPHA5 mount. Browse all deer stalking scopes and long-range rifle scopes.

Ideal For

Deer stalking at extended ranges
Night fox and vermin control
Target and gallery rifle shooting
Shooters already using a SIG BDX rangefinder

Excellent service, many thanks

great product, great customer service

The purchased product is a Nightforce ATACR 7-35x56. The waiting times were a bit long, as for many other products imported from the USA, and therefore not dependent on Xtreme Tactical who always updated me on the status of the shipment (thank you George). The product has a high cost but adequate to the characteristics of the Nightforce brand, the price paid slightly lower than the Italian one. Nightforce, is always a point of reference in the panorama of high quality optics. Very satisfied, too bad that with Brexit things are getting very complicated for Europeans.
