Revic Optics, a division of Gunwerks, created the BR4 Ballistic Rangefinder to deliver nearly instant ranges and firing solutions! This advanced ranging tool takes into account wind and earth based effects to provide accurate and extremely fast corrections to both MOA and MILS, as well as Revic’s exclusive Shoot-To-Range feature with BDC turrets (REVIC riflescopes). The display provides ample date to simplify the entire shooting process, and a series of improved ranging tools utilize target discrimination and an innovative long-range mode. Other features of the BR4 include a barometric pressure sensor, a temperature sensor, and an inclination sensor – all of which is mounted directly inside the unit and protected by a Gore-Tex membrane. In addition, the BR4 can be programmed via Bluetooth device, and Revic’s Over The Air Update protocols gives the user the latest software updates.
