Modular Rail Attach Coupler -XL Suppressor Shield (M-RAC-XL), designed to provide unparalleled performance and protection for your large diameter suppressor.
Extensively tested and endorsed by multiple military units and federal agencies, this cutting-edge design combines an optimal 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, significantly extending the lifespan of your suppressor compared to traditional fabric-style suppressor covers that trap heat inside your suppressor.
All M-RAC XL’s will include the 3.1 variation which utilizes the industry standard screw spacing of 20mm, to allow compatibility with M-LOK accessories, such as Arisaka and Surefire light mounts. This means, you’ll still be able to mount M-LOK accessories in these slots, and not waste any rail space.
Crafted with a carbon fiber outer hull, our Suppressor Shields are both impact and heat resistant, capable of withstanding suppressor temperatures spikes of 1200°F, ensuring reliable performance even in the harshest battlefield conditions.
For Standard Diameter and pic-rail mounted Suppressor Shields please see our M-RAC & U-RAC products.
*All complete Shields will ship with Stuff-Saks, High-temp thread locker, and all tools necessary for installation.
Measurement guide for length of Suppressor Shields with Rail Attach Couplers.
1. Ensure there is a 1/4″ gap between your handguard and suppressor.
Failure to have the proper gap, may cause binding on certain suppressor.
2. Measure from end of forearm to the end of the suppressor.
3. Select the closest part number to this length.
Example Measurement A = 5.9″
Choose part 18B-007-6 (6″ of coverage)

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 suppressor wrap.
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.
