For anyone with an interest in firearms and historical weapons, this is the place. The Frazier houses collections of American weaponry as well as a collection from the Tower of London.
This is a well organized and well run museum, with helpful and friendly employees. The museum itself can be overwhelming in it's size, so these are big bonuses.
The highlights of my visit were the British weaponry and a swordfight played out for a small audience of museum goers. The duel was historically accurate and the "actors" were very open to questions and stoppped several times to explain what they were doing. I found it quite interesting and I would highly recommend this show.
The main drawback about this museum, for me, was the neverending displays of guns. After awhile it becomes a tad boring, even for me (and I am quite interested in historical firearms). My recommendation is to count on getting tired of guns near the end of your self guided tour and skip what you don't find interesting near the beginning.
