- Integrated flash hider.
- 12.5oz weight.
- HUB utilizes a 1.375x24 thread pitch machined into the body of the suppressor. The HUB system allows for a variety of mounting options including both direct thread and quick-detach mounts.
- Insert the HUB compatible direct thread mount into the HUB compatible body of the suppressor and tighten it to approximately 30 ft-lbs using appropriately sized wrenches.
- Durable 3D printed 718 Inconel construction.
- Passes the SOCOM stress test for durability.
- 718 Inconel will regularly operate in excess of 1300°F and can tolerate temperatures of up to 1800°F for short periods. Extended usage in the upper temperature ranges can lead to early baffle erosion.
- Optimized for 5.56 gas-operated rifles.
- HUB compatible and includes a titanium DT 1/2x28 mount.
- The specification table lists no full auto restriction and no barrel length restriction.
- Perform inspection and cleaning approximately every 1000 rounds. Abnormal environmental conditions including exposure to rain, mud, sand, or saltwater will necessitate more frequent inspection and maintenance.
- Frangible ammunition can increase the risk of a baffle strike and is not recommended for use with suppressors. Unjacketed lead ammunition can cause lead buildup over time, reducing suppressor effectivity and leading to a potential baffle strike.
