This stainless steel rod holds an AR chamber brush or swab, one each included, on one end and has the same t-handle as our AR Lug Recess Tool. Turning a chamber brush is difficult with a normal cleaning rod, but is an easy task with this tool. Can be used with any other standard 8-32 threaded brushes or implements. Comes with one AR-15 Chamber Brush and one AR-15 Chamber Swab. Mfg: Sinclair International
