From the manufacturer

The DefCan-556 is a full-auto-rated 5.56mm suppressor that combines robust build quality with remarkable sound reduction. 3D Metal printed Inconel construction delivers durability and a high heat tolerance. Attachment is easy, using the included ZEROED SVD Muzzle Brake or a mil-spec A2 flash hider, slide the DEFCAN over the muzzle device, close the locking gate, and twist to ratchet snug.
