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