Gel Ball Double Feeding and Skip Feeding: What's Actually Wrong
Quick Answer: Double feeding (two gel balls going out on one trigger pull) and skip feeding (only firing every second pull) look like opposite problems, but they usually come from the same place: the feed path between the magazine and the chamber. Double feeds are most often caused by wet gel balls sticking together on the way through, not oversized gel. Skip feeds are most often a weak or worn magazine spring that can't push a fresh gel into position every single cycle. Fix the feed path, not the gel brand.
Two gel balls fire on one trigger pull, wasting ammo and throwing your aim off. Or the opposite: every second pull is a dead click, like the blaster's only half-loading. Players usually treat these as two unrelated faults and start swapping gel brands to fix one, then the other. Most of the time that's chasing the wrong variable.
Both faults sit in the same part of the system: how reliably a single gel ball moves from the magazine into the chamber on every cycle. Too many gels get through at once, or not enough do. Once you know which failure you've got and why, the fix is usually quick.
This is a different problem from a blaster that won't feed at all - if nothing's chambering, see our guide on gel balls that won't feed first. This post is specifically about blasters that feed, just wrong - too much or too little, on a pattern.
Why Double Feeding Almost Always Comes Down to Water, Not Size
A properly sized gel ball physically can't slip a second one through a feed tube built for one - unless something is gluing them together. That something is almost always surface water. Gel balls tipped straight from the soaking container carry a thin film of moisture, and two gels sitting against each other in the feed tube can stick as a single unit long enough to both get pushed through on the same cycle.
This is why double feeding tends to show up worse early in a session, right after loading fresh from a soak, and settles down as the gels sit and surface-dry a little in the magazine. It's also why swapping brands rarely fixes it - the new gels get loaded wet the same way, and the problem comes straight back.
A genuinely oversized or deformed gel ball can also cause a double feed by jamming the tappet in a half-cycled position, but check drainage first - it's the more common cause and the easier fix. Matched, consistent sizing like SummerCat removes gel-size variability from the equation entirely, so if double feeds are still happening you know it's drainage or the mechanism, not the batch.
Why Skip Feeding Is Almost Always a Spring, Not a Gel
Most gel blaster magazines rely on spring pressure alone to push each gel ball up into position between cycles - there's no motor doing the work. If that spring is weak, worn out, or the follower is catching, it doesn't fail outright. It fails intermittently , which looks exactly like feeding every second shot: the spring manages to push a fresh gel up in time for every other cycle, but not the one in between.
An overfilled magazine causes the same pattern for a different reason - too many gels stacked under the follower can bind against each other and the mag walls, so the spring can't push the stack up smoothly every cycle. Underhydrated gels that are still slightly hard and irregular in shape do the same thing, catching against each other instead of sliding freely.
Rule these out in order: don't overfill the mag (leave a little headroom), confirm gels are properly soaked and not still firm, then test the same gels in a different magazine if you have one. If the skip-feed follows the magazine and not the gel, the spring or follower is the actual fault.
Rule Out the Gel Itself
Still Double Feeding After You've Fixed Drainage?
Wet gel is the main cause of double feeds - dry it properly first. If it's still happening, oversized or inconsistent gel could be adding to the problem. SummerCat's matched sizing takes that off the table.
🟣 A Weak Spring Doesn't Announce Itself - It Skip-Feeds First
This is the part of the post most people never think to check.
Players tend to think of a magazine spring as either working or dead - it feeds, or it doesn't. In practice a tired spring goes through a whole intermediate stage first, and skip-feeding every second shot is exactly what that stage looks like. The spring has just enough push left to get a gel into position most of the time, but not reliably enough to do it on every single cycle under full trigger speed. That's not a random fault - it's the predictable halfway point between "working fine" and "not feeding at all."
The practical upshot: if a magazine starts skip-feeding, don't just live with it or blame the gel batch - that spring is already on a decline curve and will get worse, not better, from here. Cheap replacement springs and followers for common magazine platforms are inexpensive and worth swapping proactively rather than waiting for the mag to fail completely mid-game.
What to Do With This
- Getting double feeds? Drain gel balls properly and let them surface-dry for a minute before loading - don't tip them straight from the soaking water into the mag.
- Skip-feeding every second shot? Don't overfill the magazine, confirm gels are fully hydrated (see our growing and storing guide ), and test in a different magazine if one's available.
- If the fault follows the magazine regardless of which gels are loaded, it's the spring or follower, not the gel - budget for a replacement rather than working around it.
- Keep gel size matched to your barrel - oversized or deformed gels make both faults worse. Check our SV vs Standard barrel-fit guide if you're on a tighter bore.
A consistent, properly sized gel like SummerCat removes one whole variable from this troubleshooting process - if the feed path is still misbehaving with matched, well-hydrated gels loaded, you know for certain the fault is mechanical, not the ammo.

Frequently Asked Questions
Why does my gel blaster sometimes fire two gel balls at once?
Almost always surface water on the gel balls, letting two stick together and pass through the feed tube as one unit. Drain gels properly and let them surface-dry briefly before loading. A genuinely oversized or deformed gel can also cause it, but check drainage first.
Why does my gel blaster only fire every second shot?
Usually a weak or worn magazine spring that can't push a fresh gel into position on every single cycle, an overfilled magazine, or underhydrated gels catching against each other. Test the same gels in a different magazine to isolate whether it's the spring or the gel.
Is skip feeding a sign my magazine is about to fail completely?
Often, yes. Skip feeding is the predictable halfway stage between a spring working fine and a spring that's failed outright. If it follows the magazine rather than the gel batch, budget for a replacement spring or follower rather than waiting for it to stop feeding entirely.
Can overfilling the magazine cause feeding problems?
Yes. Too many gels stacked under the follower can bind against each other and the magazine walls, stopping the spring from pushing the stack up smoothly on every cycle. Leave a little headroom rather than filling the magazine to capacity.
Is double feeding or skip feeding the same problem as a gel blaster that won't feed at all?
No - different fault, different cause. A blaster that won't feed at all is usually hydration, dried residue in the feed tube, or gels left loaded in storage. Double feeding and skip feeding happen in a blaster that is feeding, just unreliably. See our separate guide on gel balls that won't feed if that's the problem you're seeing.
