There are US-made shotguns priced from $79.95 up to several thousand dollars. Mossberg makes several very good guns in the neighborhood of $500.
Some of the most popular gun brands made in the US include Smith & Wesson, Ruger, Glock, and Colt.
In general Mossberg firearms are well made and dependable. They are not high $$$ guns, and do not have the collector appeal of other guns, but work well. Mossberg's motto has been "More gun for your money"
The Mossberg model 283 TB was made from the 1950"s to the 1970"s. They were low priced, entry level guns.
The mossberg Model 25A was made 1936-1938. They are great little guns. I hope that this helps
