Your cart is empty.The tapered bronze bristles of the Otis chamber brush scrub the chamber, neck and shoulder of your 7.62x51mm NATO and .308 Winchester firearms. The steel bristles at the base scrub the star chamber of the locking lugs while the bronze bristles scrub the chamber clean. The brass stem is cold-welded to the core and the tip is folded, not cut. The chamber brush has a standard 8-32 thread to fit on most cleaning rods. This is the perfect cleaning brush to use with AR-10s and other .308 Winchester or 7.62 NATO rifles.

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.

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..

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.
