I might be able to shine some light on some of your questions, see answers above.How old is the marker?
probably between 5/6 years old (base don the mini being released end of 06 start of 07 and it coming with a hard case)
what sort of use has it had?
A fair bit of use but not used for approx two years until I bought it earlier this year (as the previous owner stopped playing paintball) then I sold it to viper as I was a bit strapped for cash
Have you had it from new?
Three owners from new
