steyr lg110 accessory rail blocks

Steyr/FWB/Anschutz/Air Arms/RAW (I certainly forgot a couple of brands) feature the same type UIT rail. The "european" version is commonly known as the anschutz rail and the "american" version is known as the freeland rail. The rails differ slightly in size but I think the anschutz rail is more commonly featured on match type weapons all over the world.

What blocks are you looking for specifically? The T nuts that fit in the rail or a so called hamster or are you looking for something different?

Or you can make it yourself if you have the t nuts (available at rowanengineerings website). Here's the one I made for myself:
