CMMG DEFCAN 556

 Engineered for effective sound reduction and minimal point-of-impact shift, the CMMG Defcan 556 suppressor is a high-performance, full-auto-rated suppressor designed specifically for 5.56mm firearms, featuring durable 3D metal-printed Inconel construction for superior heat resistance and long-lasting strength. Its innovative QD clamp-on mounting system allows for a quick and secure attachment by simply sliding the suppressor over the included ZEROED SVD muzzle brake.

The ZEROED SVD brake is designed to function as a muzzle device when the suppressor is detached. Turned from 4140 steel with a nitride finish, the 5.56mm ZEROED SVD Brake provides efficient recoil mitigation in a compact size. Designed to have the same exterior dimensions as a mil-spec A2 flash hider, the 5.56 SVD brake allows for direct QD attachment of DEFCAN-556 and DEFCAN-762 suppressors. 

Built with the industry-standard 1-3/8x24 HUB thread pattern, the DEFCAN 556 offers seamless compatibility with a wide range of quick-detach mounting systems, giving shooters the flexibility to easily switch mounts or muzzle devices as needs evolve. The package includes muzzle device shims and thread locker for a reliable, custom fit right out of the box. Ideal for users seeking a rugged, easy-to-use suppressor with adaptable mounting options, the DEFCAN 556 provides excellent sound reduction and durability, though it is recommended for barrels 6.5" or longer. Whether for tactical applications or precision shooting, this suppressor delivers dependable performance and versatile mounting solutions designed to keep pace with changing gear preferences. Additionally, direct thread parts are also available.

Applicable laws can vary between and within states. The item must be shipped to an FFL with SOT. This involves no ATF fee and will only occur after payment is made in full. The transfer from the buyer's FFL/SOT to the buyer, however, this no longer requires a $200 tax stamp fee that the buyer must pay (it is now free). Buyers of NFA items should be aware that ATF processing times are controlled only by the ATF, and that we cannot transfer your item until said transfer is approved. Having said that, current processing times for individual suppressor applications are very short as compared to the past (a matter of days in some cases).
