There's a reason FOR a dust cover and FA. I've had to use the FA on a AR with bad BGC just to get it back into the upper for disassembly (GO DPMS!). Guns like the Ak don't really need the dust cover where tgey're built to looser tolerances. I prefer those gadgets on the AR for my personal gun. You may or may not ever need those features. Like the slogan says "your results may vary" There wasn't enough price difference for me to justify not having them.
