Keep your AR15 clean, lubricated, and in tip-top working condition. The Real Avid AR15 Brush Combo contains all of the components needed to remove gunk, grime, and carbon from your gun's bore and star chamber. The included star chamber brush, mop, and 3 cleaning pads are perfect for scrubbing, cleaning, and lubricating your AR's star chamber. The stiff .223/5.56 bore brush goes to work scrubbing away the carbon from your bore. All items in the Real Avid AR15 cleaning kit match standard 8-32 threads, so they will, most likely, work with a gun-cleaning rod you already own.
