How to fix a jammed air rifle, pellet pistol or BB gun

On this page
This page covers general safe-clearing practice drawn from manufacturer and safety-organization guidance. I haven't had a jam worth filming on my own PCPs, which run factory slugs through a magazine, so the specific step-by-step below is general airgun practice rather than a fix pulled from my own field notes. Full methodology & editorial policy →
Step 1: Stop, and don't pull the trigger to "see what happens"
The single most important rule with any jam is the one the NSSF states for firearms and that applies just as directly here: don't fire through an obstruction. Even a small blockage close to the muzzle creates a pressure spike right at that point in the barrel, and airgun barrels are typically thinner and softer than a firearm's. A stuck pellet, a double-load, or a lodged BB can bulge or split a barrel if you fire into it. If a shot ever sounds or feels wrong, or nothing visible happens downrange, stop and check the bore before firing again.
Step 2: Make the gun safe before you touch the barrel
- Spring or gas-piston gun: uncock it. Never work on a barrel with the action cocked.
- PCP: discharge the reservoir if your rifle has a way to do so safely, or at minimum ensure the magazine is out and the safety is on.
- CO2 gun: remove or vent the cartridge.
- Every gun: point the muzzle in a safe direction and keep your face and hands clear of the muzzle end while you work from the breech.
Step 3: Match the jam to the fix
| Symptom | Likely cause | Fix |
|---|---|---|
| Won't load a second pellet, first one feels loose | Pellet not seated flush at the breech | Push it fully home with a finger or a seating tool before closing the action |
| Shot sounded weak or "wrong," nothing visible downrange | Pellet stuck partway down the bore | Stop shooting. Uncock/depressurize, push it out from the breech |
| Two pellets found jammed together in the barrel | Double-load: first pellet wasn't seated before loading a second | Depressurize, push both out from the breech, inspect for a bulge before shooting again |
| Magazine won't rotate or feed on a repeater | Mis-indexed magazine or a chipped pellet skirt jamming the mechanism | Unload per the manual, clear the jammed pellet, check the magazine for damage |
| BB gun magazine tube won't feed | BB turned sideways, tube overfilled, or dirty ammunition | Empty the tube, clear the sideways BB, reload with clean, round BBs |
Clearing a stuck or double-loaded pellet
Work from the breech, not the muzzle, whenever the design allows it. Insert a cleaning rod or a wooden dowel sized to fit the bore snugly without forcing, and push steadily until the obstruction moves toward and out the muzzle. If it doesn't move with light, steady pressure, stop. Forcing a stuck rod is how barrels get scratched, bent, or have their crown damaged, which will hurt accuracy even after the jam itself is cleared. If there's any chance a pellet broke apart in the bore (a common outcome of a double-load), assume there are two obstructions, not one, and check the barrel is fully clear before reassembling anything.
Clearing a jammed BB gun
Gravity-fed BB magazines jam differently than pellet guns. A BB that tips sideways in the feed tube, an overfilled tube, or out-of-round or dirty BBs are the usual culprits. Empty the magazine completely per the gun's manual, tip the gun to work any stuck BB free, wipe the feed path if it's dirty, and reload with fresh ammunition rather than the batch that jammed.
Preventing the next one
- Seat every pellet flush at the breech before closing the action; check by feel.
- Don't mix pellet head shapes or brands mid-string on a repeater's magazine without checking they feed reliably.
- Keep BBs and pellets clean, dry, and stored somewhere they won't corrode or deform.
- If accuracy or feeding has been getting worse before the jam happened, work through a full accuracy troubleshooting checklist rather than assuming the jam was a one-off.
- If a repeater keeps jamming no matter what you try, the magazine or rifle itself may be the problem; the six-rifle comparison in best air rifles for rabbit hunting covers repeaters chosen partly for reliable feeding.

A gun that jams repeatedly, rather than as a one-time loading mistake, is worth a closer look. If it's a PCP and jams coincide with inconsistent shots, start with why is my PCP shooting inconsistent?, and if it's feeding trouble on a magazine-fed repeater, check the magazine itself before assuming the barrel is at fault.
FAQ
Why does my air rifle keep jamming?
The most common causes are loading a second pellet on top of one already seated, a pellet loaded skirt-first or deformed on the way in, a broken pellet left in the bore from a bad shot, or, on magazine-fed guns, a mis-indexed magazine feeding two pellets at once. BB guns jam differently, usually from a BB rolling sideways in a gravity-fed magazine tube.
Is it safe to fire a jammed air rifle to clear it?
No. Firing into any barrel obstruction, however small, spikes pressure right at the blockage and can bulge or split the barrel, which is exactly the warning the National Shooting Sports Foundation gives for firearms and applies just as directly to a stuck pellet in an airgun barrel. Clear it mechanically instead.
How do I get a stuck pellet out of an air rifle barrel?
Uncock the gun or release its air charge first. Then, from the breech end, run a snug-fitting cleaning rod or wooden dowel through until it contacts the stuck pellet and push it out toward the muzzle. Never hammer on the rod or force it if it won't move; stop and check for a second obstruction behind it.
Why did two pellets get loaded into my barrel?
Usually because the first pellet wasn't seated fully before the action was closed, leaving room to load a second one on top of it without obvious resistance. Always seat a pellet flush with the breech before closing the action, and check by feel, not just by sight.
What causes a BB gun to jam?
Gravity-fed BB magazines can jam when a BB tips sideways in the feed tube, when the tube is overfilled, or when dirty or out-of-round BBs bind in the feed path. Emptying the magazine, checking for a sideways BB near the feed port, and reloading with fresh, round ammunition clears most of these.
Can a dirty or dry barrel cause jams?
It can contribute, especially on spring-piston guns where a dry, fouled bore adds friction a pellet has to overcome. But most jams are a loading mistake, not a maintenance problem; check how the pellet was seated before assuming the barrel needs cleaning. See how to actually clean one in this guide.
What if a pellet or BB won't come out no matter what I try?
Stop forcing it. Repeated force with the wrong tool is how barrels get scratched or bent. At that point it's worth a trip to a gunsmith who works on airguns, or contacting the manufacturer, rather than risking the barrel to save a service call.
How do I prevent jams in the first place?
Seat every pellet fully and squarely before closing the action, don't mix pellet head styles or brands mid-magazine on a repeater, keep BBs clean and dry, and inspect a barrel after any shot that sounded or felt wrong before firing again.
