I recently went from messing with AKs to ARs when I put together a CAR for less than $500.00. I already had a A-2 Bushmaster 20'' just to say I had one. Now I have an A-3 20'' also. I can tell you one thing for certain, after I get a EOtech (roughly the cost of a Sar-1) for the CAR, I am going back to the AKs for my fun guns. This AR thing is just too expensive (and addictive). The weapons run OK but are just are not as much fun as a AK. There are too many little things to worry about that you don't with an AK. Even the lubes cost a lot and who the hell ever heard of breaking in an AK. For what you will pay for your first AR you could get yourself a SA-M7 milled rec. carbine from Arsenal or one of the 5.45x39 Arsenal AKs (for less recoil) and save hundreds on "must have" acessories like the EOtech I've convinced myself that I need. Hell for $450.00 you can get a Yugo underfolder. You will be hard pressed get a decent AR upper for that price. Its not like I'm poor, I am far along enough in life that I can afford the AR addiction but the prudent side of me says enough already. Wait till you have that high paying job after collage to buy the AR stuff. Then you can go hog wild and be able to afford the addiction. I know one thing, after building a couple of AKs, building a AR is a piece of cake, and a lot cheaper than buying a whole one.
