Thanks for the website - I had seen the analysis, but lost track of where it was...and it is useful to totally shock the anti-gunners with this information. Many of them seem to think that it is only about 10 million “gun nuts” with an AR, plus a bunch of old farmers and ranchers. Well, not quite, there are MANY others, and the number of guns available to give to the unarmed is simply astounding.
I do take a bit of issue with “Over the fifteen years that have been recorded, there have been 1.685 NICS checks for each additional firearm added to the private stock in the United States.” That doesn’t seem right - that would imply that a lot of the NICS checks deny people the ability to legally buy a gun, and certainly doesn’t include a LOT of people who are able to buy a gun simply by flashing a valid carry license (hence no NICS check, but one or more new guns).
There are many reasons why there are more NICS checks than there are new firearms added to the stock. Two of the obvious ones are checks done for concealed carry permits and checks done to buy used guns.
A lot of guns are sold through dealers that are not new.
The numbers for adding to the stock of new guns are the sum of the legal manufacture in the U.S. plus imports, minus exports. It is likely a pretty good number.
