A new front sight holder for the GPR1 air rifle - Pardini Armi is happy to introduce a new front sight holder for the GPR1 air rifle. It is available in both a light alloy version as well as a steel variant (with item codes R001S and R001 / 1S respectively). It allows the shooter to securely clamp a SCATTÂ® training system on the vertical axis of the barrel. SCATTÂ® is a device that allows the shooter and coach to analyze the training session and identify any errors made while shooting. The new front sight holder is supplied on all newly produced rifles and can be requested as a spare part for the all existing rifles.
