Honestly, I'd say go elsewhere. I have converted 6 LA s/f blind mags to the old style DBM (has a mag release button in the side of the stock) and it is no easy task. Toughest part is finding the bottom metal. Then I had to do some grinding and cutting of the bottom of the action to make the mag and/or box fit properly. A lot of work. THey turned out really nice, but, honestly, when I was done I did not have anything all that special. Nice, but it would have been so much easier to start with a CF s/a. The only reason I did it was I had found some nice walnut stocks with cut checkering that used the old style DBM and expected it to be an easier task than it tuned out to be. If you can find the bottom metal and mag it might be worth doing, but don't buy the action or rifle first, thinking you will get the other parts later, 'cuz you might never find those parts.
