The Nosler SR-30ALTi Suppressor in black is an aluminum and titanium can developed for .30 caliber rifles (brand part no. 90620). Nosler built it for backcountry hunting and precision work, where every ounce on the end of the barrel matters. It weighs 9.2 ounces and measures 7.963 inches, with a usable caliber range of .17 through .308. It mounts over a Nosler brake or threads straight onto a 5/8×24 muzzle with the included adapter. For a hunter who wants a light .30 caliber can that stays out of the way on a long walk, this is the lightweight option in the SR-30 family.
