Thanks for the link. The puff of air is coming from well behind the bolt/barrel interface. Tissue over just the exposed bolt does not move at all. That’s what is weird about it. JMJinNC
This guy might be able to offer some insight:I did not watch the whole video, and am curious about the broken o-ring on the table.
Crosman delivered a complete new rifle today, with 2 mags, etc. Awesome customer service.
