Otis Technology 919-1M All Caliber Cleaning Patches, 1000-Pak

The Otis Technology 919-1M All Caliber Cleaning Patches come in a practical 1000-pack that covers every rifle, shotgun, and handgun in your safe. Whether you're running a .22 rimfire or a 12-gauge, these cotton patches work across the full spectrum of firearms without needing separate inventories for different calibers. Built from 100% cotton, they're durable enough to get multiple passes out of each patch—up to 6 clean surfaces per patch—which stretches your supplies further and saves money on regular range days and post-hunt cleanings.

These patches pair seamlessly with Otis's slotted cleaning rod tips, which hold the patch securely and allow you to scrub the bore from every angle for consistent, 360-degree cleaning contact. The versatility is the real advantage here: whether you're maintaining a precision rifle, a shotgun, or a defensive handgun, you're using the same proven patch across your entire collection. No guessing which size patch goes in which gun, no sorting through different products.

A thousand patches is a serious supply that won't run dry after a season or two of regular shooting. Serious shooters, gunsmiths, ranges, and hunters who put real rounds downrange will appreciate having this depth of inventory on hand. Stock them in your range bag, your cleaning kit at home, and keep a pack at the bench—you'll use them.

Frequently Asked Questions

Will these patches work for all my firearms?

Yes. These all-caliber patches are engineered to clean everything from .22 rimfire rifles up through 12-gauge and 10-gauge shotguns, so you don't need different patches for different guns.

How many times can I reuse each patch?

Each patch can be flipped and reused up to 6 times, giving you up to 6 clean surfaces before you need to discard it. That means a 1000-pack delivers significantly more cleaning cycles than the raw count suggests.

Do these patches come with a cleaning rod?

The patches themselves don't include a rod, but they're designed to work with Otis slotted cleaning tips, which attach to standard cleaning rods and hold the patch securely while allowing full 360-degree bore contact.

What's the difference between these and small-caliber patches?

These are all-caliber patches designed to work across your entire firearm collection. Otis also makes small-caliber patches specifically for .17 to .22 rimfire, but the 919-1M covers that range plus everything larger in one versatile product.
