I plan on replacing my Dads stock trigger with a Rifle Basix on his Rem 700. I was reading in the Technical Information about removing the stock trigger. It says: Installation TipsRemington receivers are “staked” on the underside beneath the mounting pins, after the factory triggers and pins have been assembled. These mounting pins are not meant to be removed. Pins must be DRIVEN out in order to remove. DO NOT re-install these pins until they have been re-fitted to the receiver. The pins may be chucked in a drill motor (like a drill bit) and reduced in diameter with 320 wet or dry sandpaper until they can be easily tapped into the receiver. Do not attempt to install any replacement trigger until, andunless, these mounting pins have been pre-fitted to the receiver FIRST. Anyone ever changed one before? I have worked on Savages but not a Rem. What about these pins? I haven't got the new trigger yet, I'm sure there will be more detail on if I re-use these pins or discard them.. Like I read on the same site: 1) Remove bolt from receiver and remove barreled action from stock. It’s a GOOD idea to take a photo of the bolt stop return spring and safety parts BEFORE removing! Remove safety parts, bolt stop release, etc. Drive out factory mounting pins and discard. Remove trigger. I am getting the LV-1 Replacement Trigger.
