Modtac U-Rac Xl Suppressor Shield Size 6.0'' Rail Type Ar-15

The Modtac U-Rac XL Suppressor Shield for AR-15 is a Picatinny rail-mounted heat shield designed to protect shooters and equipment from suppressor-related burns while keeping your rifle running cool. Built for suppressors up to 1.900" in diameter, this quick-disconnect shield uses a free-floating, air-gapped design that reduces peak temperatures without trapping heat or slowing suppressor cool-down between strings of fire. It's the kind of accessory that lets you focus on your shot rather than worrying about accidental contact with a hot can.

Modtac engineered the U-Rac XL with lightweight materials—an aluminum coupler paired with high-temperature carbon fiber construction—so you're adding minimal weight to your rail while gaining serious functionality. The quick-disconnect mechanism stays secure even under sustained fire, and the shield is compatible with standard AR-15 platforms and Picatinny rail systems. If you're running a suppressor on your AR and want to eliminate mirage signature and safeguard your hands and gear, this is a field-proven solution that works without complications.

Whether you're shooting suppressed at the range, hunting, or running drills, the U-Rac XL gives you confidence in your setup. No guesswork, no jerry-rigged solutions—just a purpose-built heat shield that does what it promises.

Frequently Asked Questions

Will the U-Rac XL work with my AR-15 suppressor setup?

Yes, the U-Rac XL is designed for AR-15 platforms with Picatinny rail systems. It accommodates suppressors up to 1.900" in diameter, so confirm your suppressor's diameter against that limit. The quick-disconnect mounting integrates directly into your existing rail.

Does the shield trap heat or slow suppressor cooling?

No. The free-floating, air-gapped design is specifically engineered to reduce peak suppressor temperature while allowing air circulation around the can for efficient cool-down between strings of fire.

What's included with the U-Rac XL?

The shield itself comes ready to mount. You'll use the quick-disconnect mechanism to attach it to your Picatinny rail; no additional adapters or rail sections are required for standard AR-15 setups.

How much weight does this add to my rifle?

The U-Rac XL is built with lightweight aluminum and carbon fiber to minimize added mass. Exact weight is not specified in the product details, but the design prioritizes a minimal footprint compared to heavier aftermarket heat shields.
