obsidian
Obsidian () is a naturally occurring volcanic glass formed when lava extruded from a volcano cools rapidly with minimal crystal growth. It is an igneous rock.Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. It is commonly found within the margins of rhyolitic lava flows known as obsidian flows. These flows have a high content of silica, giving them a high viscosity. The high viscosity inhibits diffusion of atoms through the lava, which inhibits the first step (nucleation) in the formation of mineral crystals. Together with rapid cooling, this results in a natural glass forming from the lava.Obsidian is hard, brittle, and amorphous; it therefore fractures with sharp edges. In the past, it was used to manufacture cutting and piercing tools, and it has been used experimentally as surgical scalpel blades.

I have a bunch of Obsidian and Dacite available. Small pieces, large rocks and pre-cut slabs. I also have a set of traditional and coppers tools to get you going. I also have deer sinew and Hazel arrow shafts for making your own arrows. Approximately 150ibs of rock.
Moved my subgun on, so I no longer need this 3-lug mount. Used for about 300 rounds and functions perfectly. Fits Obsidian 9 and Obsidian 45 suppressors, for attachment to 9mm firearms only.
Has several small spots of wear through the finish on the top edge (see pictures), hence the low price...
I currently have several silencers in stock and looking for a good home!
