Suppressors for the people
Fully open-source, 3D-printed & legal
This is the OP9
A simple 9mm pistol suppressor you can print for $8 of filament. It is completely legal to make it in your home provided you file some basic paperwork. There is also a 22 variant - the OP22.
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 has just 3 parts and an optional metal thread adapter. It's so easy to assemble an ATF agent could do it.
