Anybody have an idea of what happened to the supply chain of TPS rings. Trying to scrounge out a pair of 30mm and 1'" rings and all vendors list OTS until late spring. TPS online store/website lists all products as "OTS,not available". Tried to send an email to customer service but that appears to be down/OTS. Will try calling next week and see if I can connect with a "live person". Anybody hear anything..they make a great product. Thanks, Eric
