Replace your factory gauges with the well known WIKA brand. The WIKA 315 bar gauges have been known around the airgun community as one of the top quality gauges for air rifles. Filling your air rifle to the correct pressure can significantly improve your overall shooting experience. Get the shot count you’re supposed to have, and be sure your rifle isn’t going to drop below the regulator set pressure. These have also been used to achieve better accuracy for those who like tuning their rifles/regulators by using the 10 bar incremental dash marks. The WIKA 315 Bar Gauge also makes reading pressures much easier, especially for anyone who has a hard time seeing the original small lines and prefers the larger clearer print.
