So did you machine the stem or something ?!!! You can get the stem much lighter than that .

Edit, it's scandium model

Could probably lose another 15 g by smoothing out some edges but I don't feel like polishing it

I would do it .Also see if you can get the bolts hollowed . Easy to do with a drill press and carbide drill bit . Drill through the centre of the face plate or even better cut the face plate into two sections and remove the centre . Debur the edges and you would save more weight that way without compromising any strength .
