I know richard He used to work with my dad before he set up a gun shop but now sadly that shop has gone along with all the others from this area. If i remember righty he got ripped of with the patent on this rifle so i dont think he made much money out of it deffo didnt make him a fortune which it should have done to come up with an idea like this, If the big airgun companys cant build a rifle like this i think we should take are hats off to one man who did it on his own.
