I've got a Dm3 with a tadao board M5 ready installed (not sure what eye system I have in it) that I'm looking to sell on (not splitting the board out though). I've also got a pile of original DM3 / LCD bits that would go with it (grip, board, trigger, bolt parts). In addition and already fitted is an evolve bolt, aftermarket frame, trigger, clamping feedneck, can include a barrel if needed. Marker has no ASA fitted.
Don't know if this would be of interest to you from a spare parts perspective. DM3 runs fine, no issues aside from my having to drill an asa screw out of the grip when it sheared off so to put an asa on requires a std screw plus nut and bolt which I would include. To do this I had to cut a small notch out of the bottom of the board but this was just where some of the "TADAO M5" writing was and not near any of the electronics.
let me know
