CMMG DEFCAN 22 GEN 2, Suppressor, 22LR/17HRM/22WMR, Aluminum, Anodized Finish, Black, Direct Thread 22CA41E 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.
