The Q Porq Chop 8.6 Blackout suppressor is a big steel can for a big cartridge, sold here with the Rearend muzzle device (brand part no. SIL-PC-QUICKIE-86-RE). Q built it with 8.6 Blackout in mind to squeeze as much sound reduction as possible out of the heavy subsonic bullets the round was made for. All-steel construction means durability and less of the sparking seen from titanium cans, yet the can weighs only 12 ounces. It mounts on Q’s Quickie XL Fast-Attach and stays compatible with Cherry Bomb XL muzzle devices. Q says it can also pull double duty on smaller calibers.
