This one has been awesome. Once I got used to the ergonomics, I fell in love with it. Accurate, reliable (I haven't cleaned it in a few years, just to see what it's capable of, and it's still running without a hiccup), and reasonably lightweight. I don't think there's a 'best' gun, but Tavor's are pretty sweet.
How many rounds in those few years? How many is a few?
I can't help myself, I clean mine every time I get home (or at least the next day).
I'm definitely looking forward to trying one of those. I love bullpups. Worst thing is that I'll probably NEED to buy one after I run a few mags through one.
