Unless they have improved the mags, I would pass. You're right, They are light, aim well, and a hoot to shoot when they are not jamming from finicky ammo. Sore hands from beating the mags on the tailgate to get them "full."
If you want one at a good price go to Bradis and put some money down to get on a waiting list. For less than $350.00 it is worth the wait.
