The Hoppe’s AR Rifle Chamber Brush, 7.62mm/.308 Win (Model HP1325P) is a dual-diameter manual cleaning tool engineered specifically to scrub carbon, fouling, and brass shavings from rifle chambers. This specialized maintenance tool is designed to prevent feeding and extraction failures in semi-automatic platforms, such as the AR-10, as well as bolt-action rifles. As a non-powered, manual firearm accessory, it contains no electrical components and requires no SAA/RCM safety certifications or Australian mains power compatibility, making it freely merchantable across all Australian states.

Key Features

• Dual-Diameter Architecture: Incorporates a dual-diameter bristle configuration to scrub the chamber and locking lugs simultaneously.
• Phosphor Bronze Forward Section: Features softer phosphor bronze bristles designed specifically to clean the neck and shoulder area of the chamber without damaging the steel.
• Steel Rear Section: Utilizes tough steel bristles at the rear to aggressively clean carbon and debris from the locking lug recesses and main chamber body.
• Thread Interface: Features a standard 8-32 male thread, allowing it to connect securely to standard cleaning rods.

Who is the Hoppes Chamber Brush .308 for?

• AR-10 platform rifle owners — who require a specialized rifle chamber cleaning brush engineered to match 7.62mm chamber dimensions, allowing them to thoroughly scrub the locking lugs and chamber neck to prevent semi-automatic cycling and extraction failures.
• Bolt-action rifle shooters — who need to maintain chamber tolerances on their .308 Winchester (7.62mm) firearms using a dual-diameter rifle chamber cleaning brush that threads directly onto standard 8-32 thread cleaning rods.

Less suitable for: owners of smaller calibre firearms such as 5.56mm or .223 Rem, where using this brush will cause fitment failure and potential chamber damage; these users must use a dedicated 5.56mm chamber brush instead. It is also incompatible with cleaning rods featuring smaller 5-40 threads or larger 5/16-27 shotgun threads unless used with an appropriate thread adapter.
