Combine any optics on any weapon. Any number of times, anytime, anywhere.

With the continuously adjustable side and height BASIS® VARIO base rail, you can use your optic(s) on each of your weapons. You expand your basic equipment with a valuable detail that makes you 100% flexible.
100% compatible with each other and designed with zero tolerance, the two-part BASIS® system connects every weapon model with the respective target optics with absolute reliability. With really 100% reproducibility, you can use multiple target optics safely and easily on each of your weapons. Once adjusted, the mounting rail always locks to the base rail with the same torque and without play. The once queasy feeling after putting your optics on and off is a thing of the past, because the BASIS® TAC gives you, as a hunter, real confidence in your tools.
