Ok I am seriously considering a AI chassis system for my newly acquired 700. While researching I was reading that the 700 LTR SPS Tac with the REM DBM may need a kit or wont work with the AI system becasue the feed ramps are located on the Rem DBM system and not the barrel itself, which don't make much sense to me. If so I would think my local gunsmith can mill that out and then polish and port it. Can any of you shed any light on this for me? Yes this is a like 2004 or so model of 700 but I ran across a hell of a deal.
