AirTact .25 Refurb.... Noooo!

It has to go back to Hatsan. Ugghh.  When I received it I started to unbox it and I could see the left forward stock screw was loose. I could see the threads! So I tried to tighten thinking they missed it putting it back together. Nope the screw is stripped! So I emailed Hatsan asking them they wanted me to do. They sent me an RMA today to return it.  Dang I had a bad feeling. I never shot or cocked the gun. I just took it out of the box and looked it over. I kinda liked the gun based on my initial impressions (stripped screw not withstanding). I don’t know what they’re going to do (repair, replace etc.) I keep you informed.

Just got a refurb cylinder for my AT4410 and it is shooting 2.5 mil lower at 60 yds than my other cylinder. Got in touch with Hatsan and was told it was a different valve, waiting to hear back from them.

Looks like the same screws on my Edge. I just replaced the screws on mine for the same reason. I got screws that were a wee bit longer than the OEM ones. The OEM ones weren't quite long enough imo. However, the ones I got were just a bit too long. So, I used 3 washers to make up for the length. Now the stock is held more securely to the action than before. The OEM washers were those biting star washer things and they were eating through the stock. The washers I'm using now are regular flat washers. It looks like you have the same washers. I recommend replacing those washers along with the screws to save your stock.

I think the measures for the screws I got are M5 x 0.8 with a 16mm length shank. They are just a couple mm longer than the OEM.

I felt that there's two reasons why the screws got stripped. 1. The holes in the stock aren't lined up with the holes in the action. 2. The screws were too short.  Longer screws solve both those issues.
