What is a suppressor shield?
The materials and design of the MODTAC Suppressor Shields provide a solidly mounted, rigid shield that eliminates mirage, reduces the chance of incidental contact burns on personnel and equipment, as well as allows the suppressor to cool naturally, prolonging the life of your suppressor and your gear.
Are Suppressor Shields Different than Suppressor wraps?
Yes, Suppressor Shields are a rail mounted, rigid, and free floating design which does not retain heat inside of the suppressor, unlike a fabric wrap.
What Makes Modtac Shields Unique?
All MODTAC Suppressor Shields are designed to create a ~1/4″ air-gap around the suppressor, allowing air to naturally flow through and cool the suppressor.
Temperature Testing
M-RAC Suppressor Shield Temperature Testing
Temperature testing was conducted independently by SFARTAEC Instructors at Ft. Bragg, NC. Equipment: US Army M4 / URGI (11.5″) 5.56mm NATO, Geissele Rail, Surefire SOCOM Suppressor, MODTAC M-RAC Suppressor Shield 2.0
Course of Fire was 10 rounds per minute for 9 minutes (3 mags) totaling 90 rounds, followed by monitoring of temperatures during cool down cycle.
