Frequently Asked Questions

What is the importance of cleaning the chamber and locking lug area on an AR-style rifle?

Cleaning the chamber and locking lug area is critical for proper function. Carbon, unburnt powder, and brass shavings accumulate here and can cause bolt or chamber-related malfunctions if not regularly maintained, ensuring reliable operation.

What are the different thread sizes for Brownells AR Style Chamber Brushes?

Brownells offers AR Style Chamber Brushes with two thread sizes: the M16 version uses an 8-36 thread for military rods, while AR-15 and AR-10 versions use the standard 8-32 threads common on commercial cleaning rods.

How should I clean the locking lug area of my AR-15?

After brushing the chamber, use specialized Chamber Maids. These are shaped to fit the locking lug recesses precisely, effectively removing loosened fouling, oil residue, and debris that a standard brush might leave behind.

Why is it important to rotate the chamber brush clockwise only?

Rotating the chamber brush clockwise ensures it stays securely attached to the cleaning rod. Rotating counter-clockwise will cause the brush to unscrew, potentially getting stuck in the chamber or damaging the cleaning rod.
