Mine is a 2007 which is their debut year. According to Tomray who worked at Marlin NH, their are some 35K to 40K JM 308ME's prior Remington discontinuing them.
Remington did make one small run of 308ME's, I believe in 2012, then that was it. For years Remington said they would reintroduce them but never did.
My 2007 308ME shoots sub-moa and will never be sold.
