The CGS STI Six 5.56 Ti Silencer is a dedicated centerfire rifle suppressor built for modern 5.56 NATO and 6mm ARC platforms. Measuring 6.5 inches in length with a 1.64 inch diameter, it uses a titanium body produced via DMLS 3D printing to maintain precise internal geometry while keeping weight to a minimum. The included flash hider mount adds 1.125 inches of system length, bringing the complete package to approximately 11.3 ounces for a compact, lightweight setup.

Designed without barrel length restrictions, the CGS STI Six offers broad compatibility across a variety of rifles chambered in .223 Remington, 5.56 NATO, and 6 ARC. Its titanium construction and carefully engineered internals help reduce sound and recoil while preserving reliability and balance on the gun. Ideal for range use, training, and general shooting where reduced report and improved shooter comfort are desired, this suppressor reflects CGS Group’s focus on innovation, precision manufacturing, and practical performance.
