From Examiner.com:

Last Friday’s gun sales activity overwhelmed the National Instant Check System and provided retailers all over the country with a very green “Black Friday,” but did it also provide government anti-gunners a clue about how to suspend the Second Amendment?

From USAToday:

The FBI fielded 154,873 calls, a roughly 20% increase from last year’s previous one-day record of 129,166, according to bureau records.

From Market Daily News:

Fueled by fears that the Obama administration will go after gun rights during a lame duck term, the FBI reported 154,873 background check requests on Friday – a 20 per cent increase on last year’s record total of 129,166 checks.

The number of guns sold could actually be double or more that figure because only one background check is recorded per sale even if buyers purchase multiple firearms.
