I have a demo Sig BDX Sierra 6 in box with all paperwork and sunshade. I have other BDX models and this one has been mounted but not used. Anyone that is not familiar with the BDX scopes and likes to tinker with electronic options can check out the SIG site. You download the BDX app on your phone, enter the ballistic specs of your round and using a SIG BDX rangefinder or binoculars the proper LED lights on the reticle. There are two other ways to utilize the LED options without the use of a rangefinder with data sent from the app to the scope. I also have one SIG 2200 rangefinder in excellent condition available to anyone that buys a scope. This 3-18x44 is being offered for $800 and the 2200 rangefinder is offered for $175. Pics available by request.
