I don’t know to much about the 2020 HUBAN .22 it works with no function issues that I know of short of the gauge backing plate moves. That would need to be replaced but does not leak at this time. I put some JSB 18.13 down range. Fun to shoot but not my cup of tea. It is in good condition but has some visible marks. It has been used. Asking ($1000) $800 Shipped or make an offer. If you want more pics just pm me. Need this to move due to unforeseen issue.
