Otis Technology MPSR Cleaning Kit – 5.56 NATO/.223

The Otis Technology MPSR Cleaning Kit delivers field-ready maintenance for 5.56 NATO and .223 Remington rifles using Otis's proven pull-through system. Unlike traditional cleaning rods that can damage rifling when pushed from the breech, this kit's cable design follows the direction of the bullet and allows cleaning from either end of the barrel—critical for AR-platform rifles and other firearms where breech access is restricted.

Built for shooters who need portable, complete cleaning capability, the MPSR kit includes a Memory-Flex cable with slotted tip, obstruction removal tools, bronze and nylon brushes sized for 5.56mm bores, cotton cleaning patches, solvent, and lubricant. All components pack into a compact ballistic nylon case that fits in a range bag or field pack. Compatible with AR-15, M4, and other rifles chambered in 5.56 NATO or .223 Remington.
