yorkiets,
Modify the HW30 stock
I have done this with my HW99S stock - which IIRC is the same as the HW30.
I have shortened the butt by ca. 40 mm, and added some epoxy to build up the grip to an almost vertical pistol grip, allowing a straight line for my trigger finger that is parallel to the barrel.
I don't know who designed those HW stocks, but you need arms the length of a gorilla's, and ten inch fingers to reach the trigger
To finish the job off, I have painted the stock with Ford Electric Orange pearl paint
Have fun
Best regards
Russ
