DILLON RIFLE COMPANY DRC308 HUSH KIT SUPPRESSOR - COMPACT, FULL-AUTO RATED, HUB-COMPATIBLE
The DRC308 from Dillon Rifle Company is a compact, full-auto rated .30 caliber suppressor 3D-printed as a single monolithic piece in Inconel 718 or Titanium. It measures 6.5" long without its adapter and 1.75" in diameter, threads onto a HUB (1.375x24) interface, and ships with a 5/8x24 direct thread mount. The DRC308 is optimized for .308 Win / 7.62x51mm NATO, is rated up to 7.62x51mm NATO, and also works with smaller calibers such as .300 BLK.
Inside, Dillon uses its patented Purposely Induced Porosity (PIP). A series of very small vents around the radius of the suppressor gives the gas more room to be managed before it vents, which significantly reduces back pressure. The monolithic structure provides durability and thermal resistance, and the internal geometry is designed to further cut high-frequency noise. It is also slightly wider so it could take more than an inch off the length.
In independent testing by PEW Science, an Inconel 718 DRC308 earned a composite Suppression Rating of 25.9. The test host was a KAC SR-25 with a 14.5" barrel firing Lake City M80 149gr 7.62x51mm NATO.
Both materials share the same length and diameter, so the choice comes down to weight and how hard you shoot. The Patterned Inconel 718 DRC308 weighs 18.7 oz bare, and the Patterned Titanium version weighs 11.8 oz. The Inconel 718 is recommended for full-auto hosts and rifles with FRTs, and Titanium for semi-auto and bolt-action shooters who care most about weight. Dillon recommends a minimum barrel length of 10.5". Muzzle brakes, compensators, or compensating flash hiders are not recommended because they concentrate blast pressure on the suppressor's sidewalls or first baffle. Beyond the included direct thread mount, the DRC308 accepts any HUB-compatible mount.
CAPITOL ARMORY'S OPINION
Compact 7.62 cans usually give something up in sound suppression, and the DRC308 doesn't feel like it gave up much. At 6.5" without its adapter it keeps a rifle nicely balanced, and the PIP design is a big reason Dillon could shrink the length without the performance shrinking with it. If you want a short can for your .308 that still pulls its weight, this one deserves a hard look.
Picking a material is pretty simple. Running full-auto or an FRT, or just putting a lot of rounds downrange? Go with the Inconel 718 version, since that's the one built to take a beating with heat and high round counts. If you mostly shoot semi-auto or a bolt gun and every ounce counts, Titanium is a great pick and trims almost 7 oz off the Inconel model. You get the same length, diameter, and HUB mount either way.
We also like the GOV version for a cleaner look. The smooth, raw exterior keeps things simple and suits precision or duty rifles well. All in all, the DRC308 is one of the more capable compact 7.62 options out there right now.
