Well after the feedback from my 5.45 post earlier I figured I might as well ask a broader question. If you were going to buy a rifle in one of these three calibers and you were a poor college student living off of ramen noodles, which caliber and gun would you choose and why? Functionality and reliability matter more to me than pure beauty. I don't want to start an AK vs AR argument or anything, just trying to gauge peoples opinions taking the current market and availability into consideration. Some ideas I've toyed wit are the Keltec SU16C in .223/5.56 and now the Saiga in 5.45. I really like the price of bulk 5.45 and such but everything has its benefits. Opinions?
