I have a nifty Bicentennial Mini-14 NFA machine gun for sale - even has an M14 giggle switch. Only $8,500 if you want to increase your stable. I did like the Mini's I've had and agree they are much more attractive than AR's or AK's. I've just never gotten the accuracy I wanted out of them, though they are still within a minute of bad guy at most distances you would be engaging as opposed to evading. Also, they are freaking LOUD!
They have newer model Mini 14's with the AR style adjustable sights instead of the blade front sight. Haven't shot 1 yet but would like to!
