The Suppressor Shield with Universal Rail Attach Coupler (U-RAC), is designed to provide unparalleled performance and protection for, and from, your suppressor.
Extensively tested and endorsed by multiple federal and local agencies, this cutting-edge design combines an optimized air gap, efficient venting, and low thermal transfer materials for a staggering 60% reduction in both maximum outer surface temperature and suppressor cool-down time, without trapping heat when compared to traditional fabric-style suppressor covers.
Crafted with a carbon fiber outer hull, Suppressor Shields are both impact and heat resistant, capable of withstanding suppressor temperatures exceeding 1200°F. This durability ensures reliable performance even in the harshest battlefield conditions.
For Large Diameter and M-LOK(TM) mounted Suppressor Shields please see our RAS-XL and M-RAC products.

The Suppressor Shield with Universal Rail Attached Coupler, was designed to be compatible with all AR-style platforms that have a top Picatinny rail on the end of the free floating handguard. The Height over bore that we use, are industry standards, to ensure proper fitment. AR-15: 1.215” AR-10: 1.345” HK-416: 1.460” SIG MCX/MPX: 2.037 The Pic-Rail Grabber is machined to be compatible with as many commercial and military rails as possible.

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.
what makes modtac shields unique?
All MODTAC Suppressor Shields are designed to create an air-gap around the suppressor, allowing air to naturally flow through and cool the suppressor.
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 suppressor wraps, resulting in about half the cool down time, as well as a lower peak temperature.
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.
