Built into one of our standard 455 Varmint barrels, it utilizes a patented screw-in baffle system. Using the included tool, the owner can thread the baffles in to pre-designated locations within the forward threaded suppressor portion of the barrel. If they wish, they can tune baffle lengths to their liking, finding just the right combination for their load of choice. Baffles and endcap are cut from 7075 aluminum, meaning between the hollowing out of the barrel and the lightweight suppressor components, the .866” diameter Varmint barrel experiences some weight loss while still measuring in at 20.9”. Featuring a unique (and patented) baffle thread cuts through accumulated crud for regular cleanings, which is recommended be done every 300 rounds due to the dirty nature of rimfire ammunition.
