Cmmg Defcan 3 7.62Mm/308

The CMMG DefCan 3 7.62mm/308 suppressor is built for shooters who demand a serious 30-caliber can that won't quit. This 3D metal-printed Inconel construction delivers genuine heat tolerance and durability—engineered to handle the rigorous cycling of centerfire rifles without compromise. Whether you're running a precision bolt gun at distance or a semi-auto through extended range sessions, the DefCan 3 brings meaningful sound reduction to get your rifle to a safe, comfortable hearing level while maintaining the lightweight profile serious shooters prefer.

The DefCan 3 comes ready to work out of the box with an included ZEROED SVD muzzle brake (7.62mm, 5/8-24 thread), shims, and thread locker—no separate purchase required to get running. The suppressor also accepts standard mil-spec A2 flash hiders for shooters who already have a preferred setup. That modularity extends to the mounting system: the DefCan 3 uses the industry-standard 1-3/8x24 HUB interface, so if your muzzle device preferences change or new technology emerges, you can simply unscrew the existing mount and swap in a different HUB-compatible system without replacing the suppressor itself.

Weighing 22.3 ounces and measuring 8.5 inches, the DefCan 3 stays light enough for field work and compact enough for practical handling. The Cerakote finish resists corrosion and stands up to hard use. This is a suppressor built for hunters, range shooters, and precision rifle enthusiasts who refuse to compromise on quality or adaptability.

Frequently Asked Questions

What muzzle devices does the DefCan 3 work with?

The DefCan 3 comes with a ZEROED SVD muzzle brake (7.62mm, 5/8-24 thread) already included. It also accepts standard mil-spec A2 flash hiders with the same thread pitch. Because the suppressor uses the 1-3/8x24 HUB interface, you can swap out the included mount and attach other HUB-compatible muzzle devices if you upgrade in the future.

Can I use the DefCan 3 on different rifles?

The DefCan 3 is chambered for .308 WIN and 7.62mm, making it suitable for any 30-caliber rifle with a 5/8-24 muzzle thread. It's designed as a versatile can for hunters and shooters running multiple centerfire rifles that share that thread pitch.

What's included in the box?

The DefCan 3 package includes the suppressor itself, the ZEROED SVD muzzle brake (7.62mm, 5/8-24), muzzle device shims, and thread locker—everything you need to mount and secure it to your rifle.

Can I swap out the mounting system if I want a different one later?

Yes. The DefCan 3 uses the industry-standard 1-3/8x24 HUB interface, so you can unscrew the included SVD/A2 mount and attach any HUB-compatible quick-detach or direct-mount system. This design lets you future-proof your suppressor against new mounting options without replacing the can itself.
