Otis 7.62Mm Chamber Brush

This brush works well, threads are correct for most cleaning rods. Strong enough to remove baked on residue from steel case ammo, and soft enough not to damage the chamber. I'm going to get more in different sizes for my other calibers.

Works as described

Used it to clean bores of rifle used for target practice with corrosive ammo, needs good cleaning, this does it.

Otis should have an AR-10 cleaning kit that includes the chamber brush as well as the B.O.N.E. tool. Just manufacture the .223 kit for the .308 😎. BTW the 7.62 chamber brush works fine.Wouldn't expect anything less from otis.

cleans the throat of the chamber great and keeps your 308/7.62 running perfect. match it up with a mop it's perfect.

Tight fit, strong bristles

Whether you call it a semi-automatic or an auto-loader like I do, a clean chamber contributes to smooth operation. Use this brush with some solvent to loosen any carbon deposits or other dirt that can get in the way..

Works great
