[QUOTE="pmh-usa, post: 771827, member: 25707"] Running into same problem with an MPI stock blank that I'm building up for a Mod 70 (coincidence, not a M70 issue). AFTER I made sure that I had relieved enough to re-float the barrel by hogging out the forearm, this is what I did: I got some small aluminum "H" channel - cut a "trench" with a dremel in the bottom of the forearm all the way from the recoil lug trench forward to within and inch of the for end . Made it really rough and jagged, just made sure that the aluminum would be below the 'flush' line. Mixed up fiberglass resin, with some added chopped fiberglass filler to thicken slightly, and poured it in - once it was set up (fiberglass is very hard and stiff), I carefully applied 5 layers of 10mil tape to the barrel and finished glass-bedding the forearm. When that was set up, removed the action, peeled the tape off and now my forearm was rigid and free-floated. Note: if you still have a few touch points, buy some 3/4, 7/8, and 1 inch dowel - staple some 60 grit sandpaper to pieces of dowel and use to sand down the high points - if in doubt use 6 or 7 layers of tape. Good luck PM me if you like [/QUOTE]
