Air Arms Owners Club

I have been Googling this but can't find a clear answer. Is there an adjustable hamster available for the HFT500? It's height adjustment I am looking for. I have the standard Air Arms hamster and am looking at modifying it with a block of wood and some foam to increase the height but if there is an adjustable one available it will be better that the bodge job I am likely to make of my modification!!

If you are using the HFT 500 hamster then just purchase / fabricate some additional spacer blocks (it comes with one included as standard), simply purchase appropriate new longer bolts and away you go.
Alternatively Rowan Engineering (and others) manufacture adjustable mechanisms.
