From the manufacturer
The CGS STI SIX is a centerfire rifle suppressor designed for compatibility with 5.56 and 6 ARC platforms. It is engineered without barrel length restrictions, allowing use across a wide range of host weapons chambered in this caliber. The STI SIX measures 6.5 inches in overall length and features a primary diameter of 1.64 inches. The included mount contributes an additional 1.125 inches to the system length. The main suppressor body is manufactured from titanium using additive manufacturing (DMLS 3D printing), a process selected for its ability to produce consistent internal geometry and reduce overall weight. The suppressor body weighs approximately 9.3 ounces, and the complete system weight with the included flash hider mount is 11.3 ounces.
