I'm an old man, cleaning brushes for me have always been bronze, or bronze/steel in the case of the GI chamber brushes. However, I recently heard someone I respect for AR knowledge speak positively about the blue nylon ones.

Is the future already here, and it is a blue chamber brush? Do I miss "it" and become unhip with the times?

What's better about them?

I've been using them for a few years (about 6) mainly because they don't deform as readily and may be a little less abrasive during frequent cleaning.   I also keep bronze and bronze/stainless chamber brush to clean the barrel, chamber, and lugs, but I don't use them as often.  They make the chamber brushes in polymer too.

So, I wouldn't call them the new hotness or anything.  Most people just don't know about them.

BTW I'm an old man too.

I've always used my old, decomissioned toothbrushes.  I'll primarily use bronze bristles to clean a chamber (or just a boresnake), but the toothbrush does very well on parts soaked in Hoppes #9.

I've added some Nylon bore brushes to the mix because the solvents that dissolve copper do the same to bronze / brass bore brushes.

Ordered some Pro-Shot aluminum jags for the same reason.

I use them (Iosso?) because I’m just trying to get the chunks out, they are easy to clean and last a long time.

Yes nylon are better in my opinion, and the blue (Iosso Brand) are the best of the nylon.

For bores and chamber brushes.

I just used a blue nylon Iosso bore brush for the first time ever yesterday... Man that was tough to push through the barrel (I almost thought it was going to get stuck).

Bronze brushes are easy to push through the barrel.
