FAQ

gENERAL

Dillon Rifle Company currently offers the DRC556 (5.56) and  DRC308 / 7.62 suppressor.

Mounting & Threads

Yes. The DRC556 is HUB compatible and uses the industry-standard 1-3/8×24 HUB thread specification.

The DRC556 ships with a factory 1/2×28 direct-thread adapter. This is the recommended configuration and the only setup that is fully warrantied.

The Hush Kit includes the DRC556 suppressor and the factory direct-thread adapter.

Yes, HUB-compatible QD mounts may be used if they meet the required blast-chamber clearance. However, QD mounting systems are not fully warrantied.

No. Muzzle brakes, compensators, and compensating flash hiders are not recommended. These devices concentrate blast pressure on the suppressor’s sidewalls and may cause damage or void the warranty.

No. The DRC50 is not HUB compatible and uses a 1″–14 thread adapter.

The Barrett M107/M82 requires a 7/8″–14 thread. An adapter is not currently available. Modifications are not recommended and may void warranties.

Blast Chamber Clearance

The blast chamber measures approximately 1.12 inches from the end of the threads to the first baffle. Any muzzle device or adapter must not extend into this space.

Barrel Length Restrictions

The minimum recommended barrel length is 10.5 inches. The suppressor has been tested down to 11 inches.

Barrels shorter than 10.5 inches may result in excessive blast pressure, increased fouling, and potential suppressor damage.

No. The DRC50 is not intended for sustained full-auto fire and has not been tested on the M2HB.

Materials & Construction

  • DRC556: Inconel, selected for durability under high heat and sustained fire

  • DRC50: Titanium, selected for weight savings and appropriate thermal performance

Weight

  • Without adapter: 15 oz (0.93 lb)

  • With adapter: 16.8 oz (1.05 lb)

  • Without adapter: 2.6 lb

  • With adapter: 2.7 lb (final production specifications subject to change)

Caliber Compatibility

The DRC556 is optimized for .223 / 5.56 only.

 

The DRC556 is not recommended for:

  • 6mm ARC

  • .243

  • .22 Creedmoor

  • Any larger caliber

The bore diameter is approximately 0.280–0.283 inches.

Yes. The DRC50 is designed for .50 BMG and can also be used with .50 Beowulf, which produces less gas.

No. The Barrett M82A1 is not suppressor-ready. Modifications are not recommended and may void warranties.

Coating & Maintenance

No. The factory coating is approximately 0.001 inches thick and has no observed impact on suppressor performance.

Aftermarket Cerakote or paint may clog vents and can void the warranty. Proceed with caution.

Ultrasonic cleaning is the recommended cleaning method.

Accessories

Yes. Suppressor covers are compatible with the DRC556. A Dillon Rifle Company suppressor cover will be released in the future.

Performance & Technology

Dillon suppressors use PIP technology, which is not a traditional flow-through design. It is engineered to reduce back pressure while maintaining sound suppression.

Yes. Independent test data from Pew Science will be published in the future.

Warranty & Safety

Only the factory direct-thread mount is fully warrantied.

Use of muzzle brakes, compensators, compensating flash hiders, or improper HUB/QD mounting devices may void the warranty.
