Enhancing Suppressor Safety and Performance
MODTAC Suppressor Shields

Introduction
Suppressors generate significant heat during sustained fire, posing a serious risk of burns to personnel and equipment. Additionally, excessive heat can cause optical mirage distortion and contribute to premature wear on suppressors and surrounding gear. Traditional suppressor covers often exacerbate these issues by trapping heat. MODTAC Suppressor Shields offer an innovative solution by incorporating advanced materials and an innovative free-floating design to mitigate these problems effectively.

How MODTAC Suppressor Shields Work
MODTAC Suppressor Shields, advanced suppressor covers, leverage a unique combination of high-performance materials and an optimized design to enhance suppressor safety and effectiveness. Suppressor Shields are engineered with an attaching mechanism to “free-float” the Shield over the suppressor creating an air gap around the suppressor. This gap serves as a highly effective insulator, reducing extreme temperatures before they reach the advanced composite Shield. The composite Shield provides exceptional thermal resistance due low thermal conductivity which minimizes heat transfer to the outer Shield surface. MODTAC Suppressor Shields effectively leverage the two insulating layers to create a unique, high-performance thermal barrier that results in the following benefits:

Burn Prevention: By limiting direct heat transfer from the suppressor to the Shield’s surface, external temperatures remain significantly lower, reducing the risk of accidental burns.
Passive Cooling: The uninhibited airflow around the suppressor allows it to cool naturally, as if the Suppressor Shield were not present, maintaining efficient heat dissipation without trapping thermal energy.
Thermal Signature Reduction: Shield outer surface temperatures, during a moderate weapon system firing schedule, generally operate in temperature zones that are indistinguishable from surrounding environmental temperatures by many thermal detection systems.

MODTAC Suppressor Shield M-RAC suppressor cover verified third-party testing data.
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.
U-RAC Suppressor Shield testing on .308 SASS (Semi-Automatic Sniper System)
Temperature testing was conducted at the MODTAC Facility and then replicated at FT Benning GA with DOD Civilians.
Equipment: 18″ Gas-operated 7.62 NATO (M118 LR), HuxWrx Safety Co. (OSS) HX-QD-762 Suppressor.
Course of Fire was 5 rounds for minutes 1 and 2, then 2 rounds per minute until 40 rounds and 15 minutes had lapsed.

Performance Backed by Testing

Independent third-party testing has demonstrated the superior thermal performance of MODTAC Suppressor Shields:

  • A consistent 50%-60% reduction in external temperature compared to suppressor surfaces during high rates of fire.
  • Peak reductions exceeding 80% in temperature at lower round counts.
  • The free-floating U-RAC, M-RAC & PRSS models have been subjected to suppressor temperatures up to 1200°F, with no degradation observed in either the Shield or the suppressor.

Example Test Case:

  • Test Setup: 40 rounds of 7.62mm fired over a 15-minute period.
  • Temperature Increase: The Suppressor Shield’s external surface temperature increased by only 48°F.
  • Effectiveness: The delta T comparison revealed an 81% reduction in temperature between the suppressor and the Shield.

Prolonging Suppressor Longevity

Sustained high temperatures can significantly impact the effective lifespan of a suppressor. Excessive heat exposure contributes to several key degradation factors:

  • Material Fatigue and Structural Wear: Repeated exposure to extreme heat can weaken the suppressor’s metal structure, causing microcracks and reducing long-term durability.
  • Baffle Erosion: Elevated temperatures accelerate the wear of internal baffles, particularly in high-rate-of-fire scenarios, potentially diminishing sound suppression performance over time.
  • Thermal Stress on Welds and Joints: Heat cycling can weaken critical weld points and suppressor mounting systems, leading to potential failure or instability in extreme use conditions.

By allowing natural cooling and preventing additional heat buildup, MODTAC Suppressor Shields help mitigate these risks, supporting both performance and longevity of the suppressor without introducing additional thermal stress.

Key Benefits

The MODTAC Suppressor Shields deliver multiple operational advantages:

  • Burn Prevention: Protects personnel and gear from incidental contact burns.
  • Mirage Elimination: Reduces optical distortion, improving target acquisition and accuracy.
  • Extended Equipment Longevity: Enhances the lifespan of both the suppressor and associated gear by allowing efficient cooling.

Conclusion

MODTAC Suppressor Shields set the standard in suppressor heat management, improving operational safety, enabling the mission, and protecting gear. With proven testing data supporting their effectiveness, the Suppressor Shield provides a critical enhancement for professionals seeking safe, effective suppressor performance.
