Guys, thanks for input...
However I still have a dilema what to do...and here's why:
I bought my 870 Express at LeBaron in November 2008, it was originally 18" cylinder bore, 7 shot extension mag.

Later I bought here on EE 28" barrel for it - new unfired with factory tag and a modified choke included.

installed it, went on a range got my jams...
so dilema is: if I go back to LeBaron and say "hey whassup with my Remmy?

" - I can see in my magic ball they say - "Remmy we sold you is just fine - deal with the barrel guy"
and if I go to the "barrel guy" and say "hey whassup with my barrel?

" - guess what?
"... the barrel I sold you is just fine - your Remmy is FU$%#$#ED up... "
so what would experts suggest to the "cheap bustard"(c)

go to the gunsmith?
anyone knows good one in GTA?
Thanks in advance.
