Best bore snakes: five pull-through bore cleaners, and what each one leaves undone

How we picked

Bench & Berm does not test gear. Every figure on this page is published by Hoppe's or Otis Technology on their own pages, every one is linked in Sources, and anything a maker treats as a performance claim is labeled as a claim rather than repeated as fact. Here is what the ranking is actually built on.

• It has to be currently for sale, in the size we name. Pull-through cleaners are sold by caliber group, and caliber groups go in and out of stock constantly. Every pick below was checked on the maker's own store on 2026-10-23, down to the individual size.
• What is in the box beats what is on the box. A rope with a brush, a mop and a bottle of CLP is a cleaning kit. A rope on its own is one step of a cleaning. We rank the ones that admit this above the ones that do not.
• A handle and a case, not a bag. A pull-through gets filthy by design. The products that ship with a T-handle and a container are the ones you will still be using in a year.
• Honest about the chamber. No rope cleans a chamber face, a bolt or an AR gas key. Every pick here carries that in its cons, because the most common beginner mistake in this category is thinking the snake replaced the rest.
• Nothing invented. Where a maker publishes no figure — service life, how many pulls, how many washes — we say so instead of filling the gap.

What a bore snake actually is

A bore snake is a weighted cord you drop through a barrel and pull out the other end. The front is a brass weight on a cord thin enough to feed through the bore. Behind that sits a bronze brush, or on the newer designs two of them. Behind that is a long braided tail that does the wiping. One pull does, in rough terms, what a rod with a brush and then three or four patches does.

That is the whole appeal, and it is not a small one. The barrier to cleaning a gun is not technique, it is setting up. A rod kit means a mat, a vise or a free hand, a bottle open on the bench and a pile of dirty patches to deal with afterward. A snake means a rope and two minutes. The gun that gets cleaned with a snake after every range trip is cleaner than the gun that gets a perfect rod cleaning twice a year.

Before any of that, the gun is unloaded and verified clear the way your owner's manual shows it. The NRA's cleaning rule is to make absolutely sure the gun is unloaded, keep the action open while you clean, and "be sure that no ammunition is present in the cleaning area." Our how to clean a pistol page walks the whole sequence, and gun safety rules covers the handling that comes first.

BoreSnake vs Viper vs Ripcord

Three names cover almost everything sold in this category, and the differences are real rather than marketing.

The original BoreSnake is one bronze brush and a braided tail. Hoppe's describes it as a one-pass solution that uses "an integrated bronze brush to scrub out carbon fouling, while the tail clears the barrel of loose debris with a surface area 160x larger than a standard patch" — the maker's claim, and the number you will see quoted everywhere. The Den version adds the plastic case with a lid that doubles as the pull handle.

The BoreSnake Viper is the same idea with a second set of brushes. Hoppe's says the Viper "takes the technology of the original Boresnake and increases the cleaning power by adding an additional set of brushes", and adds two details worth having: a cone-shaped bore guide on the leading end, and the caliber stamped into the brass weight so a drawer full of snakes stays sortable. For a rifle bore with baked-on carbon, the extra brush is the pick.

The Otis Ripcord is not a rope at all. Otis builds it on a "rigid, helix-shaped rubber core" that it says "keeps the cleaning surface pressed against the bore, engaging the rifling", wrapped in braided Nomex that Otis rates to 700 degrees. Two consequences: it is stiff enough to push, which is why it runs the right direction through the barrel, and the heat claim is the one that matters if you clean between strings with a hot barrel.

If you want the longer argument about pull-throughs against rigid rods generally, that is its own page: bore snake vs cleaning rod. And if you are choosing specifically between the two 9mm options here, Hoppe's BoreSnake vs Otis Ripcord puts them head to head.

Which way it goes through the barrel

This is the one technical difference between the two families that a buyer should actually weigh.

A rope snake is gravity-fed: you drop the weight in and it has to go in whichever direction the barrel lets it, which on most handguns means in at the chamber and out at the muzzle, and on others means the reverse. Otis makes a point of its design running "from Breech-to-Muzzle, with no gravity feed necessary", because the rigid core can be pushed in from the chamber end.

Why anyone cares: breech-to-muzzle is the direction a bullet travels, so fouling gets pushed out the front instead of dragged back across the chamber face and into the action. Glock's own owner guidance for caring for your pistol is worth reading alongside whatever tool you buy, because the manual for your specific gun outranks any general advice on this site.

In practice, on a short handgun barrel, this is a small effect and either tool is fine. On a rifle with a chamber you cannot easily wipe, it matters more.

Buying the right caliber

A bore snake is caliber-specific, and this is where most wasted purchases happen. Buy too small and the brush does not touch the rifling; buy too large and it jams. Both makers sell by caliber group rather than by exact cartridge, which is more forgiving than it sounds.

• 9mm handgun: the Hoppe's pistol size is listed as ".357, 9mm, .380, .38" — one snake for nearly every common defensive handgun caliber below .40. Otis groups the same bores as "9mm/.38 Cal/.357 Cal".
• .30-caliber rifle: Hoppe's Viper Den size ".308-.30" covers .308, .30-06 and .30-30; Otis lists the equivalent as ".30 / .30-30 / .30-06 / .308 cal / 7.62mm".
• 12-gauge shotgun: gauge is gauge. The Viper Den shotgun line is sold in 12, 20 and .410, and Otis sells 12, 16, 20, 28 and .410 individually.
• .22 rimfire: Hoppe's lists a 0.22 pistol Den size. Take care here — a .22 bore is small enough that a snake sized for anything else will not fit.

The Viper's stamped brass weight is a genuinely useful detail if you own more than two guns, because an unmarked snake in a drawer is a snake you will eventually force down the wrong barrel.

The availability problem for 5.56

If your rifle is an AR, read best cleaning kits for the AR-15 before you buy a rope at all. The AR's cleaning problem is carbon in the bolt carrier group and the gas key, and no pull-through touches either.

What a bore snake leaves undone

This is the section most roundups in this category skip, and it is the reason the Otis Ripcord Deluxe Kit ranks second here rather than fifth.

A pull-through cleans a bore. It does not clean the chamber, the feed ramp, the breech face, the extractor, the slide rails on a pistol, the bolt carrier group on a rifle, or the gas system on a semi-auto shotgun. It does not lubricate anything either, unless you put the oil on it yourself. On most guns the bore is the part that tolerates neglect best and the action is the part that does not.

So the honest shopping list for a first handgun is a snake plus a bottle of CLP plus a rag, or an all-in-one kit. Otis builds exactly that into the 9mm Ripcord Deluxe Kit: the Ripcord, a caliber-specific bore brush, a cotton bore mop, a T-handle, a short AP brush, a microfiber cloth and a half-ounce of FP-10 CLP. That is a cleaning rather than a bore pass.

If you would rather buy the pieces separately, our gun cleaning supplies list is the full inventory, best gun cleaning solvents and oils ranks the bottles that go with a snake, CLP vs gun oil sorts out which bottle you need, and best gun cleaning mats covers the surface you should be working on.

Washing it, and when to throw it out

A snake gets dirty, and a dirty snake is dragging the grit it collected last time back down your barrel. The honest state of the published guidance: neither Hoppe's nor Otis publishes a service life, a maximum number of pulls, or washing instructions on the product pages we checked. Retailer listings for the Viper describe it as machine washable; Hoppe's own page for the Viper Den does not say so, so we are not going to state it as a maker claim.

What you can judge for yourself is the brush. When the bronze bristles are flattened or missing, the snake is a wiping tool and not a scrubbing one. When the tail is stiff with dried solvent, it is not wiping either. They are inexpensive consumables, which is the real answer: replace it rather than nursing it, and keep the old one for the dirtiest first pass.

Which one for which gun

• One 9mm handgun, nothing else: Hoppe's BoreSnake Den Pistol in .357/9mm/.380/.38.
• One 9mm handgun and no other cleaning gear yet: Otis Ripcord Deluxe Kit 9mm/.38/.357, because the brush, mop and CLP are the parts you are missing.
• A .308 or .30-06 rifle: Hoppe's BoreSnake Viper Den Rifle in .308/.30, for the second brush set.
• A 9mm, an AR and a shotgun: Otis Ripcord 3-Gun Trio. It is also the way to get a .223 Ripcord without waiting.
• A 12-gauge for clays or birds: Hoppe's BoreSnake Viper Den Shotgun, 12 Gauge.
• You want one tool to clean the whole gun: no snake does that. Start at best gun cleaning kits instead.

What to look for in a bore snake

1. The right caliber group, confirmed on the listing. Not "rifle", not "universal". The size string that includes your cartridge.
2. A bronze brush, and ideally two. The brush is the only part that scrubs. The Viper line exists because one brush is thin for a fouled rifle bore.
3. A pull handle included. Pulling a cord barehanded through a tight bore is how people hurt a hand or snap a cord. Hoppe's Den lids and Otis T-handles both solve it.
4. A case. A used snake is a solvent-soaked, carbon-coated rope. It does not belong loose in a range bag with your ear pro.
5. Honest extras, or none. A kit that includes a brush, a mop and a CLP dropper is doing more than a rope. A rope sold as a complete cleaning system is not.
6. Marked calibers if you own several guns. The Viper's stamped brass weight; a paint pen on anything else.
7. Current stock in your size. This category runs out by caliber, not by product. Check before you commit to a brand.

Beginner mistakes

• Treating the snake as the whole cleaning. The bore is the easy part. The action is what malfunctions.
• Forcing a size that does not fit. If it needs real force, it is the wrong caliber or the snake is worn. A cord that parts inside a barrel is a bad afternoon.
• Never washing or replacing it. A snake carrying old grit is sandpaper on a rope.
• Soaking it in solvent and leaving it in the case. Store it dry. Our how often should you clean your gun page covers cadence, which matters more than intensity.
• Cleaning on the kitchen table with ammunition in the room. That is the NRA rule above, and it is the one that actually hurts people.
• Buying a rope for an AR and expecting it to fix carbon. See how to clean an AR-15.
