The robust two-sided toothed profile of the prism block TOWER allows a simple and sturdy adjustment in 8 stages without spacers and discs. This offers many advantages especially when in the standing or kneeling positions. Head movements when aiming are reduced to a minimum and this reduces tensions in the neck and back.
The basic height is 27mm and can be raised in 1.5mm increments to a maximum of 38mm.
Due to the long rail of the TOWER, the rear sight can be moved closer to the eye, which is an advantage for benchrest shooters.
Prism block TOWER is allowed in all air rifle and small bore disciplines. For air rifle competitions, care needs to be taken to comply with the relevant regulations on the foresight height and the sights not protruding beyond the end of the barrel.
