mossberg slug barrel

Im changing the barrel on my 500 slugster. will be putting a 24" ported,rifled barrel with rifle sites on it. The barrel that is on it now is the 24" ported,rifled cantilevered barrel for scope or reddot,etc. Anybody interested in the cantilevered barrel let me know. Im changing to open sites because I only use it for hog hunting and only spot and stalk so its always close and would be easier for me to get sited on them better and quicker with the open sited than with a scope or reddot that's on it now
