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 its 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. .22 LR Full-Auto Rated, .17 HMR/.22 Mag Semi-Auto Rated
