Thanks everyone for your input. I have looked on Chambers and the Countrystore and all your listed mods are their from spring guides, top hats and trigger kits. I am tempted to fit the lot but at £100 it is the same as I paid for the rifle in 1996 would you fine knowledgeable people say it was worth it or is one mod better than others? I have polished the trigger and that really rekindled my love for the rifle. I do plan to have a go at making a new stock for it soon as this one has split and just doesn't fit very well.
