Well for one I figur the wife could handle the 5.45 better than the 7.62 and the price:

Right now I am trying to choose between the one above and this one:
ROMANIAN BPS AK SHOOTERS PACKAGE over at:
K, I get it.
The Romanian AK package is cheap as dirt, seems to take the double stack clips, with tapco triggers (reduces the harsher trigger slap on some Romanian varients). Most of the basic work seems done. There are loads of cheap mods and accessories for it too.
Experiences seem to vary on that weapon. Check for chromed barrel, batch quality - the stamped markings will be an indicator... will try to get you a link to that, and FReepmail later, if I can.
It is always good to diversify your ammo so going with a 5.45 is a good option.
Also, what many military folks forget (and yes I am prior military too) is that there are different guns for different battles. For instance, I would not want to use a 7.62 to clear a house or school that contains innocents because that 7.62 round will probably go thru the bad guy, the wall, and anyone on the other side of the wall, and just keep going. However, for combat taking place over distance or in the open, the 7.62 is great. Defeating body armor is alo a consideration when chosing a weapon. You have to use the right weapon for the right situation so diversification is great.
