There are many really good mag tube closure designs that have Been out there for years.

I remember when they had to completely redesign the outer tube for the 45-70's .... in thinking back, I believe it was for much the same type of failures .... I suspect that if/when it should be warranted, they would reengineer as needed .... given, ours has most probably fired as many or more than most and I fully intend to keep up the pace .... having a lifetime warranty sure ain't a bad thing
