I have an extra MDT timbr frontier chassis I can’t seem to sell. I like the chassis so I figure I might as well build another rifle to put into it. Ive been thinking about buying a 350 legend donor action off euro optic and then a 300 blackout prefit.

anyone done something like this? the chassis requires AICS mags too. Not really familiar with how that might feed in 300 blackout.

Am I trying too hard? Should I just buy a Ruger American? probably five or $600 cheaper for the same function…
