Suppressors for the people

Fully open-source, 3D-printed & legal

This is the OP9

It is the world's first fully 3D-printable 9mm suppressor. It is completely legal to make it in your home (ATF won't shoot your dog, probably).

Take a look inside

An off-axis bore allows the OP9 to be run on pistols without suppressor-height sights. This also allows the OP9 to maximize internal volume which makes it one quiet pickle.

Easy assembly.

The OP9 is 100% printed, meaning no glue or other parts are needed. It's so easy to assemble an ATF agent could do it.
