Lee Enfield No 4 MK 1* Butt Stock.

[Peter Laidler]

You WILL get it tight because the two squared shoulders on the butt on the right - close to the actual butt part will engage in the two squared shoulders at this end of the butt socket. THAT prevents rotation. What achieves TIGHTNESS is the taper between the butt and butt socked. Fit it carefully taking a gnats knacker off the butt taper part at a time and it. Knock the butt into the taper BUT NOT BY KNOCKING THE REAR OF THE BUTT until the butt seats firmly and tightly in the socket. Make sure that there's a slight clearance between the shoulder and the butt socket. Dollop of GREASE XG-279 inside the butt socket, insert steel washer, thackray/double coil spring washer and stock bolt. Tighten up with the BIT, screwdriver, stock bolt until you JUST feel the earth about to slow down on its axis in its orbit around the sun. That is tight enough
