Weighing in at a mere 5.6oz the .22LR DEFCAN-22 brings superior sound suppression to your favorite rimfire cartridges. The scant weight and 1” diameter allow the DEFCAN-22 to be as at home on a handgun as it is on the end of a rifle.

Removable end caps and baffles make user serviceability a cinch for cleanup while baffle indexing marks make for quick reassembly that assures you get optimal sound suppression once it’s reassembled. A hex opening on the front cap allows a 1/4" allen wrench or hex bit to be inserted for easier disassembly in the event any carbon fouls up the threads.

  • Rear Cap: 4140 Steel
  • Tube: Anodized 6061 T-6 Aluminum
  • Baffles: Heat Treated 17-4 Stainless Steel

Lightweight & Compact

Adding just 5.6oz to the muzzle of your firearm, it's like taping a feather to the end. The 1" diameter eliminates the need for suppressor height sights on many pistols. (Unlike those embiggened .22 cans by others)

1/4" Hex Front Cap

Use a 1/4" hex bit or allen wrench to easily remove the front cap for disassembly once you've got your DEFCAN good and dirty.

User Serviceable

Removable front and rear caps and baffle stack allow for easy and thorough cleaning of every nook and cranny.

Direct Thread Attachment

Many .22 LR firearms come with a 1/2-28" threaded muzzle, or adapter, allowing for easy attachment of suppressors... Like a DEFCAN-22 perhaps?
