My 2 cents...
...and that's all it's worth.
I have seen many Crosman 760 Pumpmasters in my time and all have been reliable, fairly accurate, and powerful enough to drop anything up to a squirrel given proper shot placement. I would buy one new,if I needed one.
I personally have a Daisy 860 Powerline (it even has a "heavy barrel!") which blew the barrel out the shroud in the first year, but after my father ingeniously used a hose clamp to hold the barrel in place, it has taken many doves and is very accurate and powerful for an airgun, 20 years later. I would have another if they still made them, but they can chamber a BB when one doesn't expect it, which led to a few idiot kids dry-firing at their siblings thinking nothing was in the chamber, which led to terrible injuries, which led to lawsuits, which led to the product being discontinued.
The 760 is like an 870, tried and true. The old Powerlines are like old Winchesters and Ithacas that would slam-fire, excellent guns but dangerous in the hands of idiots...
