@Phwe9774: The internet is your friend. Just go to youtube, search for "remington 700 trigger install", and you will have your choice of at least a dozen videos.
Trigger installation on a remington rifle may be more difficult, but I just replaced the trigger on an older, pre-accu trigger, savage 110 with a timney. Even with my limited skills, the job was simple. It took 15 minutes if you read the instructions, and 5 minutes if you didn't.
