The TriggerTech Installation Guide for the Tikka trigger is intended to demonstrate how to install a TriggerTech trigger into your rifle and verify proper safety function. This guide is directed toward experienced gunsmiths and shooters who understand the workings of a rifle and how to fully disassemble the firearm. If you are unsure, we strongly recommend retaining the services of a professional gunsmith to perform the installation and all critical safety checks. Of course, you are always welcome to contact TriggerTech for assistance.
