This review from SHOT Show 2026 covers Ridgeline Suppressors' new Arm Can and Hush Can models. The Arm Can is a 3D-printed Inconel 718 suppressor for .223/5.56 up to 6mm, emphasizing low back pressure and flash. The Hush Can features an Inconel core with a composite exterior for heat dissipation and modularity with timable brakes. Both are designed with an over-barrel configuration to improve rifle balance.
Suppressor covers, like those from Burn Proof Gear, primarily function as heat shields to prevent contact burns and reduce optical mirage caused by extreme suppressor heat. However, they trap heat, limiting their use for sustained fire and potentially affecting ballistic data ('dope'). Proper consideration of fire duration is crucial when using these accessories.
This video reviews the Magpul Suppressor Cover 5.5. It highlights the cover's construction, featuring a heat-resistant polymer sleeve over a stainless steel heat shield with steel clamps. The description emphasizes its ability to reduce heat transfer, keeping external temperatures cooler by facilitating airflow. It also functions as an insulator, mitigates visible mirage, and protects the suppressor body from impact damage. The cover is designed for 1.5-inch outer diameter, approximately 5.5-inch length round suppressors.
