Google M700 trigger adjustment. read through several articles and see if you are comfortable doing it yourself. also, and let me stress this very strongly, Do The Safety Checks when finished. if done incorrectly, the rifle will be unsafe, VERY UNSAFE! these safety checks are very important.
if you don't feel that you have the skill set or are not comfortable doing it, then let a competent gunsmith do it for you. the money spent is a bargain to have a safe and usable rifle.
another thing if you do decide to do it yourself, you need to buy a good trigger pull weight gauge. how will you know how much you adjusted or where you started at without one? you won't. i take a static reading several times and average them before i make any adjustments on any firearm to the trigger. i make several during and then afterwards. trust me, very few people can tell the difference in a couple of pounds difference!
again, Safety First. if you are new to firearms and haven't worked on very few other than just cleaning them, i might also suggest you leave this to someone that knows how to do it properly. adjusting a trigger not knowing what you are doing is very unsafe.
