Star Chamber Cleaning Foam Swabs™
AR-15 / M4 MSR Precision Cleaning Swabs | Made in the USA
Single bag includes (3) Star Chamber Cleaning Foam Swabs™
Finally, a star chamber cleaner that actually works.
The AR-15 / M4 Modern Sporting Rifle (MSR) is one of the most popular and capable rifles ever built—but anyone who owns one knows the star chamber (barrel extension) is one of the most difficult areas to clean properly. Carbon buildup, fouling, and debris collect deep between the locking lugs, where traditional brushes, patches, and cotton swabs fall short.
Swab-its® Star Chamber Cleaning Foam Swabs™ are engineered to reach where other tools can’t. The uniquely designed foam wings expand to contact 360 degrees of the barrel extension, penetrating between locking lugs to remove fouling while remaining completely lint- and fiber-free. The result is a cleaner, more reliable rifle—without leaving anything behind.
Beyond firearms, this same precision foam design is trusted for engine repair, powertrain service, and mechanical assembly, where lint-free cleaning is critical. These swabs excel at cleaning machined surfaces, grooves, ports, and tight mechanical interfaces commonly found in engines and precision equipment—making them a versatile tool in both the armory and the shop.
