I am thinking of getting an 223 carbine as a SHTF rifle. I like the 223 because it is plentiful and easy to find (unlike 30 carbine). I have an L1A1 as a battle rifle but am wanting something lighter and handier. I was considering a Mini-14 or a AR clone. I ran across a SU-16 and saw were they take the M-16 mags which is a plus in my book, but don't know anyone who has shoot them. Please help price is a major factor in this decision.
