First off, Welcome To The Forum.
The new guns coming out of Ilion have been pretty disappointing, by all accounts so far. Fit and finish issues, sloppy tolerances, yada yada yada. I'd pass on ANY gun, new or used, that I couldn't inspect first. I just found a used 1983 model a couple weeks ago, after six months of casual looking, and would suggest you bide your time and wait for a nice used one to come along.
As for accuracy.............I'll just say that Marlin has always made VERY good barrels.
