Odd location. Bottom floor of a 1970s low-rise office building.
Strange policy. Everyone who enters must sign a contract swearing not to post any photos taken in the museum on line. In the contract they specify "or in a blog." Clearly NRA isn't proud of their museum. It's as if you are touring a slaughter house and prohibited from photographing the dead animals.
Amazing collection of firearms displayed beautifully. Every conceivable type of gun dating back hundreds of years. Gun enthusiast or not, you'll be fascinated by the collection. Interior of the museum is beautiful. You almost expect to find some old southern senators sitting around smoking pipes and cigars.
If you love guns you'll be in heaven at this museum. If you have no interest in guns you'll be amazed by how elegantly guns can be shown. If you are 100% anti-gun, you'll still find the museum interesting.
