The five most popular rifles for the American Militia are the following

1. AR-15
2. M1A
3. FN FAL
4. CETME/G3
5. AK Series Rifle (Rifles chambered in three calibers of 5.56x45mm, 7.62x39mm, and 5.45X39mm)

The Ruger Mini-14/30, M1 Garand, and M1 Carbine have the same level popularity.

The SKS and WWII Military Surplus Bolt Action Rifles are also hugely popular because of their cheap price. Many militia members buys those as backup rifles to store in different locations or to have as loaner rifles. Also in states like California, where citizens cannot own rifles like the AR-15 or AK Series. Folks get them becaus ethat is all they can use.

Are the Michigan Militia the legitimate thing, or are they one of the ones I've heard about that are anti-government and all?

They're unorganized militia. They're not antigovernment. Just very weary of it. Check out their page and see what they preach.
