I took heart from your comments and proceeded to mount my Savage Varminter Bipod on the Survivor F/E. I put a closely fitted wood block inside the forward end of the Survivor F/E that had a press-fit splined nut in it . I drilled Thru the F/E and threaded the quick attach bolt for the bipod into the press-nut, tightened it down and mounted the bipod. About 1/2 hr. work. The proper location for the bipod may be elsewhere , but it goes on easy.There is a wood-screw type bolt holding the forward sling swivel that could be replaced with a longer one that could be run into the forward end of the wood block parallel to the barrel axis that might re-inforce the wood block mounting. The only thing lacking is the fore/aft positioning of the bipod,and if you wanted 1 more possible position a little further back, you could reverse the ends of the block as the vertical screw is positioned to the rear of the block.
