What are the differences between these two models?
I know that they're the long action versions of the M590/M595, and have found reference to a derilium (sp?) bolt sleeve on the M690? What is this and what does it do? Why wasn't it used on the M695?
The M690 was earlier than the M695 right? What years were they produced?
I've found an M690 i'm interested in, so any info appreciated.
