Thread: Modifying a lightweight "plastic" stock

I got a Howa mini Stock off Tararua Phil to bubba to fit my 13yr old, but It's not what I think of a "plastic" stock, like the one on my older Browning A-bolt.

It feels harder than classic glass reinforced thermoplastic, and doesn't sand like it either. It's more like fibreglass, or some sort of harder skin over a softer core. It also weighs 600g as opposed to the listed one and a bit kg for a factory Mini stock.

Has anyone modified one of these? I want to reshape the wrist/pistol grip area, but don't want to sand/file through a skin into soft/hollow core if I can avoid it (though if I have to I could re-skin it).

Thought I'd ask before I drill a small hole to find out what's inside it.
