Hatsan USA says it's available at "FieldSupply.com, AirgunDepot.com or PyramydAir.com." I searched all three of the sites but the Vortex model doesn't show up. I emailed all three site tonight but haven't received any responses yet.I had the Benji Trail gas piston pistol for a week and sent it back because the sites would not adjust enough to hit the bulls eye.
I have the spring version , Model 25 Super Tact in .177 . Cocking is stout, & recoil is a little, too. It didn't take me long to get used to it , though. It was shooting close to 700 fps, then suddenly dropped to under 500. I contacted Hatsan, returned it, & had it back within 2 weeks. All is well, now & I am pleased with it. I wouldn't mind having some type of small scope on it , but not sure what to buy & which one would hold up to the recoil.http://www.hatsanusa.com/products-page/spring-powered/mod-25-super-tact/
