Sometimes I’m amazed at how well simple can work.If I remember that scope, it’s going to show up with pci.rail type rings and your M_rod likely has the .22 grooved receiver. Could get new rings...or this simple spring loaded set of adapters. No real recoil to a PCP, found them to actually be a simple fix that works AND is easily removable if you want to use that nite site on a rifle that does have a pic.rail.Amazon.com : LIVIQILY Tactical 11mm Dovetail to Picatinny Rail Adaptor Mini Snap-in Conversion Mount : Sports & Outdoors So like $8….which seems a sin for an expensive scope, but all I can say is that it works for me.
