It has an integrated spring that automatically jumps to the next position after firing a shot. Thus, the ten pellets can be fired semi-automatically at high speed. The Steyr Pro X system operates with a maximum cartridge pressure of 200 bar. The integrated regulator ensures constant energy. More than 200 shots can be fired with a filled cartridge until you have to go back to your compressed air tank or pump again.
The Steyr Pro X is a regulated multi-shot and semi-automatic PCP Bullpup air rifle with a beautiful walnut ambidextrous stock. The 200 bar cylinder, the two-stage match trigger, the 520 mm match barrel, the 10-shot magazine, the Biathlon side lever system, and the extra-long cylinder (more capacity) make this a very accurate PCP air rifle but its also a pleasure to shoot with. The automatic repeating action allows ten quick shots directly out of the magazine.
