I think the dates for the suspect trigger (2nd) variation) are 2007 to 2014. Mine is the 3rd variation. I was just wanting to upgrade to get a crisper pull. I do not have any huge issues with accuracy, but want to refine my results if I could.From what I've read I am guessing that there are three types of triggers that have been used on the Rem 700. The first was on the rifle from its introduction in 1962 until some date- I know not. Trigger number 2 is the one that had issues. How it differed from the first one - I know not. It was replaced by the third variation which has evidently satisfied the ambulance chasers but does little as an aid to the shooter. If this information is correct and anyone has the approximate dates of the changes; I'd appreciate learning. and of course if the information is wrong or there were further variations, I'd like to hear the correct information.
