ZeroTech has introduced an Adjustable BDC Turret that mounts on the elevation caps of thirteen Thrive X and Thrive HD riflescopes. The accessory costs 69 dollars and uses five independently lockable markers sitting above the existing MIL or MOA scale.

Shooters can reposition those markers without tools to match a new cartridge or weather data instead of ordering another engraved cap. A selector on top frees one marker while the others stay fixed.

The product works only with listed B-designated models, so buyers must check the exact SKU.
