I would like to replace the x-mark trigger on my Rem 700P with a Triggertech diamond 2-stage. Sadly, this trigger is only available for clone actions and not for "factory Remington 700". Triggertech web site seems to imply that there is a difference between the bolt release on the factory rifles and clones. I own two Remington 700P rifles and no clones, so I have no idea what this difference might be. What is the difference between the Remington factory rifles and clone actions with respect to bolt release? Can the Remington factory rifle be modified by a competent gunsmith to accept the Triggertech 2-stage?
