I think AG and i were seperated at birth
I once had a club member who bought a s400K from a mate's mate
. It would start off at 16ft/lb and gradually drop with each shot until after 12 shots was almost empty. On stripping it i found that someone had drilled the Transfer port, messed with the firing valve/pot and put spacers on the hammer spring. We got on the phone to the seller who basically said 'tough titty, sold as seen'.
. I then said 'no worries mate, i'm taking the rifle to the police station now so make sure you have your FAC ready'. Oddly enough the seller then agreed to give £50 back to the chap and i fitted a new body and set the rifle up as it should be.
