I started this project three or four months ago, planning to develop a rifle stock that can be used for prone shooting and F-TR and still have rigidity in the stock. Some stocks are not as rigid as they should be for F-TR. There is a fine balance between making a stock light enough to use a heavy barrel and having it be strong enough. By using a lighter wood stock material like spruce, I could keep the full size of the stock, and maintain the rigidity. Including buttplate and cheek adjuster, it is 3 1/2 pounds, and probably with some adjustments I could get it under 3 pounds.
