Does anyone have an idea how long it should take to hear back from customer service? I talked to a very nice lady in a call center 5 days ago about my Rio Grande. (It came with the wrong front sight on it, way too short.) She didn't have a clue about guns and said she had no way of connecting me with anyone that did but that she would try to get information back to me. I offered to email the information to her so she could pass it on in writing and she agreed and gave me her email address. I have emailed her 3 times but haven't heard back. The first two emails went through but the third came back as a non-existent address. I know all firearms companies are busy these days but I expected at least an acknowledgement. Is there another way to contact someone who actually works on firearms at the company?
