Our apologies for the delay. We have been at SHOT Show.
Due to the way that the Wilcox Filter fits the Objective lens, the RFR will not work correctly with the Filter installed. Our apologies for the incorrect information on our website. We will correct it. If you would like to get a refund for your purchases, we will be happy to provide you with an RMA. If you need one, please contact us at firstname.lastname@example.org
Again, our apologies for the confusion.
