Im really kickin this around, There's a local gun shop here by me that has 2 used Mossberg 510 mini's. The one is 410ga and the other 20ga. Im more interested in the 20ga. its Mossy Oak Obsession camo for $249.00. I've read some of the issue these guns have, most seem to be simple fixes. So is worth the $249 used price? Thanks for any thought on this!
