Nickona, that Galil looks amazing.
To be frank Ed, I wouldn't use 6 full mags in day again. Even RA-tech parts are not indestructible ("we use steel" - yes, but there are countless types of steel, all with varying quality...). I'm not saying don't do it, but... you'll certainly see enhanced wear and tear if you do.
That said, assuming you get the kind of accuracy and range I do, you'll be lucky if you ever need more than 2, possibly 3 mags in a day, as once I know what range it's shooting (on that day) I can generally just point and click.
Do give it a chance though. Mine drove me nuts when I got it, but I'm glad I kept with it. The moment there's a place to post it on the forums, I'll be adding my review, from the perspective of 6 months use.
