Can we say FAL rifle, select fire. Chambered in 7.62x51/.308, it is every bit of an "assault rifle". The term is a word made up by the media/politicians to scare the general public, don't fall for it. Yes, the correct term would be battle rifle, just like the current M16/M4 series is the current battle rifle of the US.
I would pick up a FAL, CETME, G3, SCAR, simply because they may be harder to find. Compared to the amount of AR's (Armalite Rifle, not assault) out there. A better return for resale down the road.
