Well, I'm something of an anachronism I guess, but I started off with a fixed collapsable stock which I didn't mind that much, switched to an A2, which I found to be more comfortable than the previous fixed stock. I also enjoyed the ability to carry cleaning gear in the trapdoor compartment. I also eventually picked up a four-position CAR stock, which I tried out a couple of times, but couldn't quite convince myself that I liked it more than my A2. So I presently have an A2-stocked carbine. Whatever floats your boat, I guess.
