CMMG ZEROED 30 .30 Caliber Direct Thread Suppressor Built for .30 caliber or smaller centerfire cartridges, the CMMG ZEROED 30 suppressor delivers maximum sound suppression and robustly overbuilt quality at a no-nonsense price. Constructed entirely from heat-treated 17-4 stainless steel with a surface-hardening gas nitride finish, the ZEROED 30 offers outstanding corrosion resistance and a combat-load full auto rating of approximately 240 rounds between cooldown periods. At 6.5" overall length, it is purpose-built for .30 cal platforms such as the .308 Win DMR, 300 BLK PDW, or 7.62x39mm carbine. All ZEROED suppressors are manufactured 100% in-house at CMMG&';s Boonville, MO facility, ensuring maximum quality control and competitive pricing. The ZEROED 30 includes two HUB compatible direct thread mounts (1/2"-28 and 5/8"-24) straight out of the box, providing immediate flexibility for a wide variety of host firearms. The tubeless laser-welded baffle design, combined with 7/8" wrench flats on the mounts and a 3/8" square drive end cap on the suppressor, makes disassembly simple using common tools. Cleaning is equally straightforward: use nearly any solvent or an ultrasonic cleaner with confidence. Product Highlights Full Auto Rated: All ZEROED suppressors carry a full-auto rating with approximately 240 rounds between required cooldown periods, making them ready for the most demanding use.
