Sub2000 Buttstock Extender

Have you ever wondered why Kel-Tec made the buttstock of the Sub2000 so short (in height)? I have to scrunch my head and shoulders down just to see through the sights! So I designed and made an extender. It really helps a bunch!!! The extender slips onto the existing buttstock.

09Feb24: I added a tapered version of the extender.
