The Spartan 3 sound suppressor is a lightweight, durable, compact, direct thread 5.56mm silencer.
The Spartan 3 was designed to provide the end user with a durable, compact, lightweight suppressor at an affordable price. The Spartan 3 is unique in that it is 6.25″ long and comes pre-drilled for pinning and welding to barrels as short as 10.5″ to achieve a suppressed SBR with only 1 tax stamp required (total length of 10.5″ barrel with Spartan 3 pinned is 16.1″ and NFA compliant) With this objective in mind, an optimized silencer was built. The Spartan 3 is CNC machined and TIG fusion welded for maximum thermal transfer, strength and durability. Every component in the Spartan 3 is manufactured from high strength, high temperature, corrosion resistant alloys.
