Currently running a Lite Rail and want to swap in out for the RIS II. Is the bolt up system different, or can I just use the bolt up system from the Lite for the RIS? I have searched and found both answers...

The LITE and RIS II do NOT interchange, you would need to pull the barrel nut and replace the collar.
