I went with the mini for a couple of reasons. Its very very similar to the M1 Garand and M-14 gas system which is more then proven. It is stone cold reliable no matter how dirty it is (good mags are important in any weapon. Even my M-14 will fail with crap mags... which is about the only thing that will stop it.
). I like that the mini has a handle that can clear just about any kind of jam. An its plenty accurate and can be made even more so for either free or next to nothing from the info on this board.
Black and scary? My mini is now
. If you wanna know more check out my thread in the gallery. State/local law might make the choice for you.
.223 or 5.56? Doesn't matter both the mini and AR shoot both.
High caps? Both have them. Good and bad.
Cost? I dont know for sure about ARs but I know you can find deals on minis. I got mine with wood and BC folder, Ultra Dot red dot, Assault systems bag, and about a dozen 30rds for a little over $400. As with everything if you have the time to look around you can find a good deal on either I would bet.
Ammo? I know a mini will eat anything but I dont know about an AR.
The world is a dangerous place to live, not because of the people who are evil, but because of the people who don't do anything about it.
