Swab-its® AR-15 / M4 MSR Star Chamber Cleaning Foam Swabs™ – Precision Firearm Cleaning Swabs
MADE IN THE USA | MSR STAR CHAMBER CLEANING SYSTEM
Finally, a Star Chamber cleaner that works.
The MSR (Modern Sporting Rifle) is one of the most popular and versatile rifle platforms, but it is also one of the most difficult to clean. The Swab-its® Star Chamber Cleaning Foam Swabs™ are specifically designed to access and clean the AR-15 / M4 barrel extension (star chamber)—an area known for tight tolerances, locking lug recesses, and heavy fouling buildup.
The star chamber is the interface between the barrel and upper receiver. Its locking lug geometry creates hard-to-reach pockets where carbon and debris accumulate, making traditional brushes, patches, and mops ineffective.
Swab-its® Star Chamber Cleaning Foam Swabs™ solve this problem with a precision-engineered foam design that expands and compresses to deliver full 360-degree contact inside the chamber.
