How The Suppressor Shield works

The MODTAC Suppressor Shields work by utilizing a combination of existing, but no commonly used materials on the market as well as the proper design.
All our Suppressor Shields are designed to create about a 1/4″ Air-gap that surrounds the suppressor. This air gap works as a great insulator, and limits the heat transfer out to the surface of the Shield. This air gap also allows air to naturally flow around the suppressor, so it cools down much faster than when wrapped with some sort of insulating fabric suppressor cover.

Internal and third party testing has shown a consistent 50%-60% reduction in temperature of our shield compared to the surface of the suppressor, with some tests showing over 80% reduction in temperature, especially at lower round counts.  All of our free-floating Suppressor Shields, (U-RAC and M-RAC) have been tested with up to 1200 degree suppressors, showing little to no degradation.

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″) 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.

What does this mean?

The materials and design of the MODTAC Suppressor Shields provides 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.
