There's nothing wrong with the regular stock. I actually have a tapco stock on my backup AK, a regular one, not a M4 style, and I'm going to either replace it with the original wood, or just break down and buy a full bulgarian polymer set, cause the tapco has a weird cheek weld for me..
I don't think it's too long either, unless you are very tall, I'm 5'9", and it fits me fine with or without body armor. Only thing I wish was different was the buttpad, I would prefer some rubber like on a vltor or sopmod M4 stock, and have the butt be flat, not curved.
Unbroken, the best way to determine what's best for your team is to actually go out and train with the rifles, you'll learn what works and what doesn't.
