OK, guys. I need the lowdown on the AB-10's. If they're worth having, I'd like to buy one while they're still available. I've heard different stories on these things, and for the money, I don't expect a Walther. Are there any inherent problems such as jammimg. Are they a blowback or lock up design? How's the accuracy with the short barrel? Most of my stuff is of good quality and I don't want to waste money on something junky.
