Why NSP thought it was OK to enlarge the tap hole thus allowing blow-by is beyond me!

I shall be measuring the loading apertures now - may have to go down the brass sleeving route to get any oversized ones back to 5.52/53 or whatever is correct.

JB said it was Sussex Armoury produced the rifles. Most of the components being made on the local trading estate. He said quick fixes have to be carried out otherwise production is expensive. Like most .22" taploaders maximum power and soft shooting was only achieved using the contemporary Eley Wasp. Just the same as an Airsporter I used to have. BSA sold a little kit to expand the skirts of Wasps to get maximum power out of their S models. It made an enormous difference to the shooting characteristics.
