Scope mounting parts for No.1 Mk3 HT

[Son]

Just thinking out aloud Son, but the trouble with an SMLE is holding the xxxx thing square and secure in the first place. Any knowledge as to exactly how parallel the bottom surface of the body is to the axis of the bore? Comments............

I've got a barrelled action loose at the moment, I'll get it out and clamp it onto a flat surface and project a light through the bore or something- I'll get back to you shortly....




Ok, I'm back.
I set the barrelled action up, clamped gently so the bottom surface of the action was held down flat. I turned the lights off and stuck a single LED torch in the muzzle and then the chamber to project a spot onto a block set up at the opposite ends. I marked the centre of the spots and measured their height above the surface to be the same at each end, over a span of four feet. Conclusion from this rough experiment- the axis of the bore appears to be parallel with the bottom surface of the action.
