Ron/MikeI put a 1/4 drill bit through the hole in the clevis at the end of the ram. I also measured the part that Mike suggested. Everything appears to be the same thickness
I love it when a plan comes together.......

I think they had to trim something like a half mm (0.020" ?) off the end of the new Vortex to get all the holes to line up properly with the holes in the comp-tube. That seems possible based on some of the "loose" tolerances I've measured on other Hatsan parts.I'll see if I can find the post and provide a link.BEFORE trimming ANYTHING I would take the calipers to several parts to identify if one of the dimensions REALLY NEEDS trimming.I know it is discouraged but I made a small hardwood mallet that I use to coax in stubborn cross-pins. Most of the time I DON'T need to use it, but sometimes a few GENTLE taps helps things move forward.My calipers have a dead battery. The new gas ram came with a new end cap. I compared the new end cap with the original and they are the same size. No problems there that I see.I then measured the new and old gas rams. The new gas ram measures just at 6 and 5/8 inches from the brass ring to the end of the assembly. I did not measure the gas piston rod. The old gas ram measures between 6 9/16 and 6 5/8 inches from brass ring to end of the assembly. The body of the new gas ram to the end of the assembly is longer than the original. I believe this is the problem. I could contact Hatsan to send me another, but risk being in the same situation. Or I can grind off the difference. My head is leaning toward Hatsan owning this one. Michael, thanks for presenting the fact that someone else had this issue.Sorry, have not found post yet.I had a really NICE Mitutoyo dial caliper at work for almost 18 years. Supplied by employer so I surrendered it when I left. Purchased a digital caliper for home use. EVERY TIME I tried to use it the battery was low or dead. GRRRR! Did that stoopid battery dance for almost a decade, then purchased a good DIAL CALIPER for home/airgun use. Very happy again using a dial caliper. Never going back to digital this lifetime.I THINK the critical dimension to get all 3 holes to line up in comp tube might be here (see attached).Can you measure the thickness of the old and new Vortex at the location shown in your edited photo?
