The J. Dewey Chamber Rod (brand part no. CHR) is a 1/4-inch diameter brass shaft with a female 8-32 thread built to accept standard chamber brushes or mops, making it especially useful for M16 and AR-15 platform cleaning where a dedicated chamber tool speeds the job up. The 9.5-inch brass shaft is long enough to reach the chamber area without disassembling the upper.
