The Brownells Chamber Mop in cotton is a practical cleaning tool built for AR-308 and .308 Winchester rifle maintenance. This 12-pack gives you enough mops on hand to keep your chamber and locking lugs clean without running out mid-cleaning session. The dual-purpose design tackles two critical areas with a single tool—the long, thin section slides into the chamber where individually-tied cotton strands work like multiple brushes at once, while the shorter, wider diameter end addresses the locking lug recesses where powder residue and fouling accumulate. If you run an AR-308 platform rifle or a bolt-gun in .308, chamber cleanliness directly affects reliability and accuracy, and these mops make the job straightforward.
Cotton construction is a reliable choice for chamber cleaning. The mops attach via standard 8-32 threads, so they'll work with any cleaning rod equipped with a compatible jag or adapter. At roughly 3 inches long, they're sized to do real work without being unwieldy. Whether you're breaking in a new upper, performing routine maintenance between range sessions, or deep-cleaning after a long hunting season, having a multi-pack means you won't improvise with a worn-out mop or skip the chamber when supplies run low.
Brownells chamber mops are a working shooter's choice—straightforward, no-nonsense tools for keeping the parts of your rifle that matter most in good condition.
| Caliber/Platform | .308 Win / AR-308 |
| Material | Cotton |
| Thread Size | 8-32 |
| Length | Approximately 3 inches |
| Quantity | 12 mops per pack |
Yes. These are sized for both AR-308 platform rifles and .308 Winchester bolt rifles. The dual design—long section for the chamber and short section for locking lugs—is particularly useful on AR-pattern builds where lug recess fouling is common.
Any cleaning rod or rod adapter with standard 8-32 female threads will work. Check that your existing cleaning kit has compatible threads or a threaded jag that accepts 8-32 attachments.
That depends on how often you clean and whether you reuse mops or replace them each session. A 12-pack gives you plenty for regular maintenance or lets you use a fresh mop each time you hit the range.
This is the cotton version. Cotton is effective for chamber cleaning and is widely compatible with standard solvent-based cleaners and lubricants.
