Have a Rem700 AAC and went to adjust trigger and couldn't get it anywhere near where I would like it (2.5-3#). What do I need to do to get it there or should I just get an after market trigger to drop in? I really don't want to spend hundreds of dollars (rifle is for my dad who only hunts with it, couple weeks a year only). Just looking for a clean breaking trigger around 2.5-3#. Thanks all!
