IOSSO NYFLEX RIFLE BORE BRUSHES Reviews & Ratings

Tough, long-lasting bore brushes thoroughly clean handguns, rifles and shotguns. Distinctive blue Nyflex bristles flex more than bronze, letting you scrub back and forth without fear of getting the brush stuck in the bore. Easily scrubs out all types of fouling, and the brass wire brush core won’t scratch the bore. Handgun and rifle brushes have 8-32 male threads, and shotgun brushes have 5⁄16-27 male threads. Sold as single brushes.

They work great!

Pretty simple, they are fantastic brushes that last through a few cleanings with ThorroClean on barrels with heavy lead and copper deposits. Brings the barrel back to a shiny mirror-like surface.

Best bore brushes made

Notes are slightly over size and therefore do a much better job cleaning and they last longer too.

Works great for my 6XC!

I tried other 6mm/24 cal. brushes, and they are too large causing the cleaning rod to bend while trying to push it through the bore. These brushes have the right amount of friction to clean the bore without bending the rod. I highly recommend them for 6mm/24 Cal. guns.

Great Brushes

I love these brushes. I will admit that the first pass or two are very tight, but then they really shine. I have used these brushes for a few years now and wouldnt use any others. I have used then on stubborn copper fouling and carbon build up. They get into the lands & groves and remove a lot of stuff other brushes didnt get. Ive gotten a long life out of each one.
