Temperature Testing

MODTAC independent testing utilized commercially available tools to identify the measurable difference between suppressor temperature and the outer surface of the Suppressor Shield (Performance Capability) of the free-float version of the Suppressor Shield.
Product Specifications

Suppressor Shield Selection
Measure length (A) shown on image above. [Front edge of forearm/rail to end of suppressor]
Note: We recommend the Suppressor Shield be shorter rather than longer than the suppressor if the measurement comes out in between sizes.
Take length (A) and subtract 3/4″ for the total width of the coupler.
Suppressor Shield length = (A) – 3/4″

- Standard Venting – The “standard” vent design is optomized to deliver maximum mirage reduction while enabling air flow from the below the suppressor, up and around the suppressor body to encourage natural cooling.
- CQB Venting – Our CQB vent design focuses less on mirage reduction and more on protecting the operator. By increasing the amount of hot air that can escape, the CQB vent design promotes faster cooling while still offering maxmimum burn protection.
