Safety is in the correct place for starters *wink*
They work.
Folks buy these for various reasons, and they flat work right out of the box.
Some removed nicer guns (Model 12, 870s, Ithaca 37s...) from Tractors, Barn, Farm/Ranch, guest house, cabin duty and bought these.
Now I did not grow up with Mossberg, never saw or heard of Mossberg in my parts, except for the pistol Mossberg did back in the day.
Duck Hunting and other hunting needs, decided to get some guns for guests, and farm/ranch kids to use.
Walked in, bought a few, went out without cleaning and they run...
Bought more, and then read instruction book and all.
So for the money, out of the box, these have worked in duck blinds in freezing rain and ice, busted doves, felled deer, and ridden in trucks, tractors and the like.
I mean unload, hit them with a air hose and dust fly everywhere, or use the garden hose, even power washer to clean [doesn't everybody do this?] .
Lube? Toss me the John Deere oil, that'll be fine...
