If someone is dead set on owning a semi-auto centerfire, the only one that's worth a hill of beans IS the BAR... But, like any semi-auto rifle, you MUST keep it clean, lubed and rust-free..
The only item on the BAR I run into from time to time, (maybe 1-2 times/year) is a sheared timing latch pin.. About a $40 repair, total - including the pin.., tops... And that's after that rifle has gone through a fair number of rounds..
FWIW..
