All you need - Otis Technology Round Cleaning Patches

Very innovative idea from Otis for a cleaning patch that is essentially universal. I've used these patches on a 5.56/.223 up to 45ACP very successfully. A little pricey compared to other patches. However, when you consider that this is the only patch you'll need, the somewhat higher price is offset because you'll no longer need to buy caliber specific patches. These are the only cleaning patches I'll use.
