I'm new to the forum so I apologize if I'm posting in the wrong section, or anything of that nature. I currently own a Remington 870 Wingmaster. I wanted to get a swivel from Uncle Mike's website so I can carry it around easier. I'm trying to find the right one for my gun. I found this one: Uncle Mike's - Remington Model 870 Express And this one: Uncle Mike's - Remington 870 & 870 Youth I'm afraid I don't know the difference between the two and I don't want to order the wrong one. Thank's in advanced for your help.
