Removing SMLE Fore-end Rear Screw Wire

[Parashooter]

. . . I could gouge/chisel out a small square around threaded rod/screw wire on one side of the fore-end enough to grab it with a pair or pliers and twist it out . . .

Unfortunately, the divot you'll make to grab the "wire" will likely create a considerably larger exterior blemish than a thin-wall hollow drill would leave. (The drill can be made by filing teeth on the end of a steel tube with I.D. matching the O.D. of the "wire".)
