Took it by the dealer in Hot Springs today and they've not seen this part before either. I'm the 2nd owner so
I'm thinking either I a crazy boy and this part didn't fall out of the gun (maybe from the ceiling fan or out of my head ?). I'll make sure the gun shoots OK at the range and if so move on.
Dealer in Hot Springs suggested sending the photo to Rohrbaugh to see if they notice it.
Picked up a Bianchi Belt holster, 5 extra springs, and box of Winchester 115 grain Silvertips while at the store today.
