MODTAC designed the Suppressor Shield – Universal Rail Attach Coupler (U-RAC) to provide a free-float suppressor cover solution to the majority of standard forends with top picatinny rails.Top picatinny rail systems maintain a standard height over bore, which allows the Suppressor Shield to be centered over the suppressor in a free-float configuration. Please check the Fitment Guide to see if your forend is compatible.

Hardware

– Aluminum hardware provides a strong, light coupler.

Attaching Mechanism

– Free-float

– 1/4 turn, quick attach/detach Suppressor Shield

– Recoil proof design

Design

– Air gap provides air circulation around suppressor.

– Vents are placed to minimize mirage and maximize air flow.

– Free-float design reduces heat transfer from suppressor to Suppressor Shield.

Materials

– High Temperature resin can withstand suppressor temperatures of up to 1,000°F for short periods of time.

– Filament wound carbon fiber provides unparalleled rigidity/strength to weight ratio.

– Carbon Fiber possesses a low thermal transfer rate, protecting the operator and equipment.

– Cerakote coating provides a long-lasting, durable surface.

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

U-RAC Suppressor Shield length Selection

Measure length (A) shown on image above. [Front front 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″

“A” length (in)	Suppressor Shield length (in)	Part
5.50 – 6.00	4.75	18B-004-4752
6.00 – 6.75	5.50	18B-004-552
7.00 – 7.75	6.25	18B-004-6252
7.75 – 8.00	7.00	18B-004-72

For (A) measurements longer than 8.00” please contact us at info@modtac.us

Part	“A” length (in)	“B” diameter (in)	Weight (oz)	Vent Options
18B-004-4752	4.75	2.00	7.0	CQB
18B-004-552	5.50	2.00	7.25	CQB

Fitment Guide

The Suppressor Shield U-RAC is based on standard picatinny top rail heights. Depending on the front slot design, the U-RAC should fit most rail systems and can be used in combination with a wide variety of suppressor models up to 1.65″ outer diameter.

If you have a question for a specific rail, please contact us at info@modtac.us or 720-608-8609.

Standard Venting – The “standard” vent design is optimized 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.
