Yeah stock altering only works a little bit if you add it on the butt. Extend to much and geometry all messed up. Better longer and shallower angle from the start. Miroku stopped doing one. There used to me a model 500 but browning weight made it unpopular I think. yildiz has the plastic painted over wood grain which is nasty looking. Lincoln don't make em, Fausti and Gamba ..didn't know about them can't see any uk stockist though?
