The Otter Creek Labs Universe-36 multi-caliber suppressor is built around a 36-caliber bore (Otter Creek Labs part no. UNI36). Rather than being tied to one cartridge, it is designed to move between host firearms in calibers up to that bore size. For a shooter with several rifles or pistols in different chamberings, one multi-caliber can is a simpler and more economical path than a dedicated suppressor for each. It is the standard Universe-36; an FDE version is listed separately.

Key Specifications

• The bore is 36 caliber, the largest projectile size the can is built to pass.
• It is a multi-caliber suppressor, designed to serve several hosts rather than a single cartridge.
