Cmmg Suppressor Defcan 86 8.6Blk 350Leg

The CMMG Suppressor Defcan 86 is a centerfire rifle silencer engineered for shooters running 8.6 Blackout and other large-bore cartridges up to .36 caliber. Built from 3D metal-printed titanium, this suppressor delivers serious sound reduction without the bulk—it tips the scales at just 14.8 oz and measures 8.1 inches in length, so it won't turn your rifle into an unwieldy beast on the range or in the field. Whether you're shooting subsonic loads or full-power magnum rounds, the Defcan 86's generous internal volume handles the noise without flinching.

What makes this can stand out is its no-nonsense engineering: no minimum barrel length requirement means you can run it on short-barreled uppers and pistol-length builds without compromise. The industry-standard 1.375-24 HUB mount pattern gives you flexibility—swap between direct thread and quick-detach mounts as your setup demands. This unit ships with a 1/2-28 direct thread mount, and it's finished in durable Cerakote to handle hard use.

If you've invested in an 8.6 Blackout build or you're looking to tame a big-bore rifle, the Defcan 86 gives you the suppression you need without adding unnecessary weight or length. It's the kind of can that lets your rifle work the way you designed it.
