The Nosler SR-22ALTi Suppressor in gray is an aluminum and titanium can for .22 caliber and smaller firearms, including 5.56mm rifles (brand part no. 90602). Nosler fits a titanium blast chamber and blast baffle where heat and erosion are worst, then uses aluminum components to keep weight and cost down. It weighs 9 ounces and measures 7.533 inches, so it adds little to a lightweight varmint or predator rifle. Nosler recommends it for full-length barrels with standard-pressure cartridges, the bolt-gun and predator work where rapid strings are uncommon. It mounts over a Nosler brake or threads straight onto a 1/2×28 muzzle with the included adapter.
