I can only echo Crowbeaner. Mine has been a fine hunting rifle since purchasing it in 1976.
I have never had a jam, failure to feed or failure to fire. It is also no more "ammo finicky" than any of my other rifles. It will shoot Winchester and Federal with 1.5" groups if I do my job. Now it isn't as fond of Remington because the groups will open up to about 2". Bear in mind a 2" group will kill pretty much any deer.
No, it probably isn't as slick as a BAR BUT, you can comfortably carry it many more miles than you can carry the BAR.
