I also purchased the same gun last august,
it worked fine until 2 weeks ago, I was
at a tactical shotgun match and the gas
chamber broke off of the barrel. I
called Remington and they said they would
send one out that day, it took 2 weeks
before I recieved a replacement and
it was a shiney gray, not even close to
my flat black barrel, it also was 18 7/8
long and the front rifle sight could be pushed
out with finger pressure!!!
hope yours is a keeper. Relode
