The CMMG DefCan 2 5.56/223 suppressor is a full-auto-rated can built for shooters who demand both durability and serious sound reduction on modern sporting rifles. Its 3D metal-printed Inconel construction handles sustained fire and high heat without compromise—ideal whether you're running suppressed duty drills, hunting, or putting rounds downrange at the range. At 7.8 inches long and 19.8 ounces, it balances real noise reduction with a compact footprint that won't throw off your rifle's handling.
The DefCan 2 arrives ready to mount. It ships with a ZEROED SVD muzzle brake (5.56mm, 1/2x28 thread) and shims, so you can get behind the gun without waiting for additional hardware. The Cerakote finish protects against corrosion and abuse—important when you're actually using the thing in the field. The real smartness is the HUB-compatible design: the suppressor uses the industry-standard 1-3/8x24 HUB system, which means you can unscrew the included SVD brake and swap in different HUB-compatible muzzle devices down the road. Your can keeps working with whatever new gear you adopt.
If you're running a 5.56 rifle and want to keep things quiet without fuss, the DefCan 2 delivers. Full-auto rated means it's built tough enough for anything you throw at it. Thread locker is included to keep things locked tight.

Frequently Asked Questions
Can I use the DefCan 2 on a standard 5.56 rifle?
Yes. The DefCan 2 is chambered in 5.56x45mm NATO and ships with a ZEROED SVD muzzle brake threaded 1/2x28—the standard thread pitch for most 5.56 rifles. Shims are included to help achieve proper fit and concentricity.
What if I want to switch to a different muzzle device later?
The DefCan 2 uses the industry-standard 1-3/8x24 HUB mounting system. You can unscrew the included SVD brake and attach any other HUB-compatible muzzle device without replacing the suppressor. This makes it easy to adapt as your setup or preferences change.
Is the DefCan 2 rated for automatic fire?
Yes, the DefCan 2 is full-auto rated. Its 3D metal-printed Inconel construction is designed to handle sustained fire and the heat that comes with it.
What comes in the box?
The package includes the suppressor itself, a ZEROED SVD muzzle brake (5.56mm, 1/2x28), shims for fitment, and thread locker to secure the brake.
