ZeroTech Optics USA has introduced new turrets featuring five numbered markers that shooters can move without tools to match current ballistic data. The markers sit above the usual MIL or MOA scale so users keep both custom references and standard elevation information. A selector on top unlocks one marker at a time.

The product fits certain B-designated ZeroTech riflescopes, with compatibility depending on the exact model. The Nashville company backs its optics with a Triple A Lifetime Warranty covering any owner and any problem without a receipt.
