When purchasing Sig Sauer or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

The SIG Sauer BDX system can make sure that you get the most accurate shot possible. It is designed to be used with the Kilo1600 BDX LRF and Sierra3BDX 3.5-10x42mm riflescope combo kit. This kit is perfect for hunters who want to have a lightweight optic that doesn't weigh down their rifle system.

The BDX system uses the Kilo1600 BDX rangefinder to collect data on the range and windage. The software calculates a shooting solution based on the rifle and ammo combination and sends it to the Sierra3BDX riflescope. This illumines a holdover point inside the scope reticle. The Sierra3BDX riflescope has a tube size of 30mm and an adjustment value of 1/4 MOA. The reticle is available in the second focal plane.

The Sierra3BDX 3.5-10x42mm riflescope is equipped with the company's LevelPlex anti-cant system, which ensures the optic is level for in-scope adjustments. It also has HD glass and a BDX-R1 Digital Ballistic Reticle. Shooters can use this reticle to shoot out to 800 yards with a guaranteed 1-MOA accuracy.
