I’ve been keeping in touch with HatsanUSA. My 135 Vortex Ram died a while back and I have been wanting to convert it from a gas ram to spring. I know several other members who have expressed this same interest. HatsanUSA just got some in. They shipped mine right out. Ordered it Tuesday and it arrived today. $39.95 plus $9 shipping. I’m looking forward to the conversion and tuning. They have been difficult to get so who knows how long they will be available. The kit includes: spring, spring guide, two washers, receiver cap.
