This table (link) shows what the Fed collects in excise taxes on all sorts of stuff, including the category, "Firearms and Ammo".

If any of you are knowledgable about such taxes, could you please decipher what this means to us consumers in dollars and cents for such items?

Of course, when we buy guns and ammo, these taxes are already built in to the price we pay; we see no item "excise tax", but it's there. Of course, state sales tax is on top of that.
