I've spoken a bit about my M5x DBM and described verbally the difference between the "x" and the de-facto standard M5, so I thought I'd show everyone what the "x" is all about.
Notice the circled protrusion with a blind hole that houses the Pre-Load Piston, and, in some stocks, material will need to be relieved to allow the fitment of the protrusion.
One will note that in the DDG Lot Test Fixture, there's no "wall" of material between the mag box feature and trigger inlet area of the stock. If one has a stock with a wall of material there, simply remove enough of the material to allow the protrusion on the DBM. Everything else about the "x" is all standard M5.
The only other area to be revised is on the bottom of the receiver (rimfire and centerfire alike), just ahead of the trigger pocket. A small, blind depth plunge with a 1/4" end mill creates a pocket that allows the vertical movement of the piston when the magazine is inserted into the DBM.
All of my new actions will be set up from the jump with the features that accommodate the Pre-Load Piston.
