OUCH.............. I bet that made the number stamps sing when he whacked them like that! The barrel nuts (and the catches) are diamond hard........... You'd shoot out a barrel before you wore out a barrel nut, believe me. As a matter of interest, what backsight did they/SA use? Was it the bog standard Mk3 .303/yards backsight or a recalibrated 7.62mm sight.

It was said that the .303" backsight could be used on the 7.62mm guns if you read the yard range scale as metres. That might have been sort-of correct UP TO about 100 yards but thereafter, following a logarithmic scale of whitewash, it was a total farce. Or in official Army terminology heard in Armourers shops of the era, ' load of total bollo......' What's the word I am looking for now?

What the .303" gun was useful for was as the sub calibre aiming gun for the early big and beefy MOBAT and lightened CONBAT as both trajectories were a match. Sorry for wandering off course a bit
