The Nosler SR-30K Compact Suppressor in black is a short aluminum and titanium can for .30 caliber hunting rifles (brand part no. 90664). At 5.834 inches and 7.2 ounces, it is built for hunters who want the rifle to stay short and balanced behind the muzzle. That matters most on longer barrels, which can feel unwieldy behind a full-length can in a tree stand or ground blind. It covers a .17 through .308 caliber range and mounts over a Nosler brake or by direct thread with the included 5/8×24 adapter.
