It would be great if someone could offer modified M70 buttplates with traps in them. The pre64 buttplate, IMO, is about as popular on custom rifles as the Niedner and of course there are hundreds of thousands of Winchesters, not just 70s, that use this buttplate. I for one would cheerfully chop a big hole into the butt of a stock 70 to have a place to hide a sight slide. And when the time comes to sell the rifle, just put a regular plate back on it and pass off the hole, if ever found, as a lightening cut.
