Greetings! I recently got a Hatsan Invader 5.5 cal. semi-automatic PCP rifle, but due to Hungarian laws 7.5 Joules is the allowed energy, and the corresponding air pressure is not enough, it does not pull up the loading bar, the rifle does not charge. There is no professional service here in Hungary! How should it be set to load the projectile as well - because it pulls the hammer back, but not the bar! I tried with a stronger rf kick, but then it didn't work either! Someone has an idea, thank you - Petibácsi- Hungary
