Chamber Boss™ – AR15

The Real Avid Chamber Boss is the dedicated AR-15 chamber cleaning tool — purpose-built to reach the star chamber, barrel extension, and bolt-face geometry that bore rods and generic brushes can’t touch. Everything you need stores neatly inside the ergonomic handle.

Why Shooters Choose It

• Self-centering handle aligns inside the AR-15 upper against the barrel extension lugs — delivering precise chamber contact every time
• Star chamber brush scrubs carbon from lug recesses, feed ramp, and chamber interior in a single spin
• 5 wool star chamber cleaning pads follow the brush pass to absorb residue and apply oil with controlled dosing
• Internal tool storage — star chamber brush and cleaning pads seal inside the handle for range-bag carry
• Pivot Lock included — holds the upper open hands-free while you work the chamber

Designed For

AR-15 owners who know that chamber carbon — not bore fouling — drives extraction failures and reliability issues. Fast, effective, and purpose-built for the platform.
