Help Please...w/ Rem 870 rifled barrel

[bearring0]

I ordered a rifled barrel on ebay for a Rem 870 12g.. but it has the extender cantilever base missing. Ive looked and cannot find them anywhere on the web..
Does anyone know of a place that sells them, have that cantilever base, or have another rifled barrel they would part with.. in either 12g or 20g..
THANKS.
It should look like this... the base itself

At one time, Gun Repair Center had them. Might wanna give them a holler. https://gunrepaircenter.com/search.php?search_query_adv=Cantilever

You’re welcome. I think I have a complete cantilever barrel, but I don’t have the cantilever by itself.
