I thought I remembered reading a while back about certain scope mounts causing barrel seperation on these pumpers due to the mounts latching onto the barrel instead of a scope rail. I currently have the Crosman 4-Pc Intermount.

Should I be concerned about barrel seperation?
I was told I can not use the Air Venturi Intermount as they don't fit the older models.

If I need new mounts, is my only other option the Ingvar Alm mounts and are they still availible?
Those mounts will work. I use them on my vintage Sheridan and my Benji 392. I use pistol scopes on these rifles so I can load and pump without any problems.
Years ago Sheridan made a mount that dug into the joint but these new ones don't.
A new mounting system is in the R&D stage that will mount the scope lower to the barrel. Check all the INTEGRABASE postings on this site
I plink, therefore I am.
