The Otis Technology .223/5.56 Gun Cleaning Kit is a dedicated cleaning kit for AR-15 platform rifles and other .223/5.56 firearms — sized brushes and cables specifically for the bore diameter. Memory-Flex cable pulls fouling from breech to muzzle in the bullet’s direction of travel.
The .223/5.56 specificity matters for AR owners who clean frequently — caliber-matched brushes work harder than oversized brushes that don’t make full contact with the rifling.
Otis Technology has manufactured gun cleaning kits in Lyons Falls, New York since 1985.
