WTT 20" barrel 8 shot tube for 24" rifled 5 shot Listing ID: 2977192

Wanting to trade the 20" barrel and 8 shot mag tube off of my new unfired 590 for a 24" rifled barrel and 5 shot mag tube from a 500. Prefer to be in similar condition to mine (new and pristine) but let me see what you have. Will include 10 shells of 3" remington rifled slugs that I won't be able to use. Also will toss in the ghost ring sights since they won't work with the new barrel (I think). And if it doesn't fit the new barrel, will also come with heat shield (I'm new to shotguns, bear with me). Thanks! I'm in North SA in the Black Hawk neighborhood near Stone Oak and Bulverde. Not selling parts as I'd like to keep it functional.
