I just picked up a almost new ATN PS-22 HPT on ebay and want to use it conjunction with my Bushnell HDMR and don't want to send the rifle out to have the Badger or US Optics rail installed. So for now I'm just going to try the adapters that they have that it attaches directly to the objective bell of your scope. I was wondering if anyone knows which of the adaptors I would need. Is there anyone out there that can chime in on this. Thanks.
