Aluminum Jags Eliminate Annoying False Positives on Patches

Conventional brass jags work great — except for one thing. They can react to solvents, leaving a blue “false positive” on patches. In recent years, jag-makers have experimented with many different materials in an effort to cure the solvent-reaction problem. Today we have polymer jags, nickel-plated jags, and stainless steel jags. And the latest innovation is the aluminum jag from Dewey.

J. Dewey Mfg. offers a series of “Copper Eliminator” jags and brush adapters made from aircraft-grade aluminum with the same hardness as brass. Dewey claims that its aluminum jags will not become embedded with grit or particles that could harm your bore. At the same time, Dewey’s aluminum jags will not react to ammoniated bore solvents that can turn patches blue green when used with brass jags. Dewey aluminum jags are offered with either male OR female 8/32 threads. The $5.25 aluminum jags and $3.70 brush adapters are offered in a wide variety of calibers. You can order these products from Dewey Mfg. or Brownells.
