I have a hunting partner that has a 6 year old BAR. It is a great gun, accurate(although not sub 1/2" accurate) and has taken many deer. But, he found out that the BAR can break as his gun sat in the gunsmiths shop for the last two weeks of firearms season. Seems something broke causing the gun not to eject. I realise a bolt rifle can malfunction too, but it is much less likely to do so.
