Remington 783 .22LR Magazine Compatibility

Someone lands on a marketplace listing at 9 p.m., types "Remington 783 .22LR magazine" into a search bar, and orders a 10-round .22LR magazine because the listing title looked close enough. Two days later the magazine shows up, it won't drop into the well, and the return window is ticking. This happens more than you'd think, and it's not the buyer's fault — the model numbers and calibers get crossed in search results constantly. Let's settle it plainly: the Remington 783 does not take a .22LR magazine, in 10-round capacity or any other capacity, because the 783 was never built in .22LR.

This article walks through exactly what the 783 does chamber, what its real magazine capacities are, why a rimfire magazine physically cannot work in it, and where you actually find a 10-round .22LR magazine if that's what your rifle needs. If you're not sure which rifle you own, that's step one, and we'll cover how to check it in under a minute.

Why 'Remington 783 .22LR Magazine' Searches Lead You Astray

The confusion usually starts with cross-shopping. A shooter owns a Marlin rimfire rifle and a Remington centerfire rifle, or is comparing the two brands' magazine ecosystems side by side, and the model numbers blur together in a search bar. Search engines and third-party marketplace listings don't always help — a seller might title a listing "fits Remington/Marlin rifles" as a catch-all, which is misleading at best.

The Remington 783 was introduced as a budget-friendly centerfire bolt-action hunting rifle, built in short-action, long-action, and magnum receiver lengths to cover common big-game calibers. It was never engineered around a rimfire cartridge, and Remington's rimfire and centerfire product lines use entirely separate receivers, bolt faces, and magazine wells. There is no factory 783 variant in .22LR, .22 WMR, or .17 HMR.

If you're comparing how Marlin and Remington approach detachable magazines generally, our Marlin vs. Remington magazine comparison breaks down the two systems side by side, which is a better starting point than guessing from a listing title. The short version for this article: if your rifle is a 783, you're in centerfire territory, full stop.

What the Remington 783 Actually Chambers

The 783 was built around three receiver lengths, each matched to a family of centerfire cartridges. Short-action 783s cover calibers like .223 Remington, .243 Winchester, 7mm-08 Remington, and .308 Winchester. Long-action 783s cover .30-06 Springfield, .270 Winchester, and .25-06 Remington. Magnum-length 783s cover cartridges such as .300 Winchester Magnum and 7mm Remington Magnum.

None of those calibers is .22LR. The smallest cartridge the 783 platform was ever chambered for is .223 Remington, which is a centerfire cartridge with a bottlenecked case roughly 1.76 inches long — nowhere close to the dimensions of a rimmed .22LR round. The receiver, bolt, and magazine well are all machined around centerfire case geometry from the start.

For a deeper breakdown of exactly which magazine goes with which 783 chambering, our guide on short-action vs. long-action 783 magazines lays out the differences receiver by receiver. If your rifle is chambered in .308 Winchester specifically, we also have a dedicated writeup on the Remington 783 .308 magazine that covers fitment and capacity for that exact caliber.

Remington 783 Magazine Capacities by Action Length

Capacity on the 783 tracks the cartridge, not a flat number across the board. Short-action and long-action 783 magazines — covering .223 Rem, .243 Win, 7mm-08, .308 Win, .30-06, .270 Win, and .25-06 — are built as 4-round detachable box magazines. That number is consistent across those standard chamberings because the magazine body only needs to be long enough to stack four cartridges of roughly similar case length.

Magnum-length 783 magazines are a different story. Because magnum cartridges like .300 Win Mag run longer overall, the magazine body has to be the longest of the three lengths — but that added length goes toward accommodating the longer cartridge, not more rounds. Magnum 783 magazines hold 3 rounds, one fewer than the short- and long-action versions.

That's a detail worth double-checking before you order, because it's counterintuitive — the physically largest magazine holds the fewest rounds. A few points to keep straight:

• Short-action 783 (.223 Rem, .243 Win, 7mm-08, .308 Win): 4-round detachable box magazine
• Long-action 783 (.30-06, .270 Win, .25-06): 4-round detachable box magazine, longer body than short-action
• Magnum 783 (.300 Win Mag, 7mm Rem Mag): 3-round detachable box magazine, longest body of the three

If capacity limits matter for where you live or hunt, verify current law in your state before you buy — our magazine capacity laws by state page is a starting reference, not legal advice.

Why a .22LR Magazine Will Never Fit a 783

This comes down to basic cartridge geometry, not manufacturing preference. A .22LR round is a rimmed, straight-walled rimfire cartridge about 0.6 inches long overall. A centerfire cartridge like .308 Winchester is a rimless, bottlenecked case nearly 2.8 inches long overall. The feed lips, follower shape, spring tension, and magazine body dimensions built around one cartridge type have nothing in common with the other.

Even if a .22LR magazine were somehow forced partway into a 783's magazine well — which it isn't designed to do — the feed lips wouldn't align with the bolt face, the extractor wouldn't engage the rim correctly, and the round wouldn't chamber. At best you get a jam. At worst you damage the magazine catch, the follower, or the magazine well itself trying to make an incompatible part work.

This is the same reason a .22 WMR or .17 HMR magnum rimfire magazine doesn't work in a .22LR rifle either, even though both are rimfire. The magnum rimfire case is longer and fatter than .22LR, so a magnum magazine won't feed .22LR reliably, and a .22LR magazine won't accept magnum-length rounds at all. Caliber-specific means caliber-specific — there's no cross-compatibility shortcut in either direction, centerfire-to-rimfire or rimfire-to-rimfire.

How to Identify Your Rifle Before You Buy

The fastest way to avoid ordering the wrong magazine is to stop guessing from memory and go look at the rifle. Every Marlin and Remington bolt-action or semi-auto rifle in our catalog has its model number stamped on the left side of the barrel, near the receiver. That number is the ground truth — not the box it came in, not what a relative told you, not what a marketplace listing assumes.

Once you have that model number, match it directly against the magazine description on the product page you're about to order from. A legitimate listing will state the exact model number it fits, not a vague "compatible with Remington and Marlin rifles" blanket claim. If a listing can't tell you the specific model number, that's a reason to keep looking rather than order and hope.

This two-step check — barrel stamp, then product page match — takes less time than filling out a return form, and it's the same method we'd recommend whether you're buying a single magazine for a weekend hunt or sourcing for a gunsmith's parts counter.

If You Actually Want a 10-Round .22LR Magazine: Marlin 795

If a 10-round .22LR magazine is genuinely what you're after, the rifle you're almost certainly holding — or shopping to replace a magazine for — is a Marlin 795, not a Remington 783. The 795 is a .22LR semi-auto that was designed around a detachable box magazine from the start, which puts it in a completely different category from tube-fed rimfires.

The 795's original magazine is the 7-round 71900 — the magazine the rifle was built around. Marlin also produced the 71901 as a factory option. Beyond those two, American Rifle Magazines manufactures two 10-round .22LR magazine variants for the 795, giving you a 7- or 10-round .22LR magazine option depending on how much capacity you want on hand. The 10-round version isn't a generic aftermarket knockoff — ARM makes it as a US-made, factory-correct part built to the same fitment standard as the original.

Worth noting separately: some Marlin rimfires in this general family are tube-fed and take no detachable magazine at all. If you're not sure whether your rifle takes a box magazine or loads through a tube, that distinction matters before you buy anything, and checking the barrel stamp against the product page (as covered above) will settle it. For background on the 795's magazine lineage and how it compares across the Marlin rimfire family, see our piece on Marlin rifle replacement magazines.

Common Mistakes When Shopping for Replacement Magazines Online

Most magazine mismatches trace back to a handful of repeatable mistakes. The first is trusting a listing title over the actual product description — titles get keyword-stuffed to catch more searches, and "Remington/Marlin compatible" in a headline doesn't mean it fits your specific model. Read the fine print, not just the headline.

The second is assuming brand consistency means part consistency. Owning other Remington or Marlin products doesn't tell you anything about a specific rifle's magazine well — model number is what matters, not brand name alone. The third mistake is skipping the caliber check entirely and assuming "it's a .22-something" is specific enough; .22LR, .22 WMR, and .17 HMR are three different rimfire cartridges with three different magazine requirements, and none of them interchange cleanly.

A fourth mistake, more relevant for centerfire buyers: ordering a magazine based on caliber alone without confirming action length. Two 783s chambered in different calibers can need different magazine bodies even within the same general family, which is why the short-action/long-action distinction matters as much as the caliber does. When in doubt, our OEM vs. aftermarket rifle magazines guide covers what to look for in a listing regardless of which platform you're buying for.

Feeding Reliability: Why Magnum and Rimfire Magazines Don't Mix

Feeding reliability is where a mismatched magazine shows up fastest, even in the rare case where a part almost fits. A magazine's feed lips are tuned to the exact rim or case taper of the cartridge it was designed for. Change the cartridge and the round either sits too high, too low, or at the wrong angle relative to the chamber, and you get failures to feed, failures to extract, or a round that noses down into the magazine well instead of up into the chamber.

This is true within rimfire calibers, not just between rimfire and centerfire. A .22 WMR or .17 HMR magnum magazine does not fit a .22LR magazine well, because the magnum rimfire case is both longer and larger in diameter than .22LR. Loading .22LR into a magnum-spec magazine, or trying to seat a magnum magazine into a .22LR rifle, is a reliability problem waiting to happen even on the rare occasion a part appears to insert.

The practical takeaway is simple: match caliber first, then confirm action length or capacity second. Never treat "close enough" as good enough on a magazine, because feeding failures at the range or in the field are exactly the kind of problem a correctly fitted, US-made magazine is supposed to prevent.

Caring for Your Correct Magazine Once You Have It

Once you've confirmed the right magazine for your 783 or your 795, keeping it running smoothly is mostly about routine, not gear. Wipe down the exterior after range sessions to keep grit out of the follower channel, and periodically disassemble the magazine to clear out powder residue and dust that builds up in the body over time. A magazine that feeds sluggishly is often just dirty, not defective.

Check spring tension every few hundred rounds by loading it to full capacity and letting it sit loaded for a day, then cycling it — a spring that's lost tension will show up as sluggish feeding or rounds that don't rise fully to the feed lips. Store magazines partially or fully loaded in a dry environment; modern magazine springs are rated for long-term compression and won't weaken meaningfully from storage alone, but humidity and temperature swings will still affect the metal over years.

For a complete cleaning walkthrough, our magazine maintenance essentials guide covers disassembly and cleaning step by step, and it applies whether you're maintaining a centerfire 783 magazine or a rimfire 795 magazine — the process is the same even though the parts aren't interchangeable.

Your Next Step

Before you order anything, go check the model number on the left side of your barrel. If it reads 783, you're shopping centerfire, and you need a short-action, long-action, or magnum magazine matched to your exact caliber — not a .22LR magazine in any capacity. If it reads 795, you're in .22LR territory, and a 7- or 10-round magazine is the right call depending on how much capacity you want.

Either way, match that model number to the exact listing on the product page before you check out, not to a general brand name or a catchy title. Browse our full lineup of US-made, factory-correct Remington 783 and Marlin 795 magazines, confirm your rifle's model number, and order the one built specifically for it — that's the whole fix, and it takes less time than a return shipment ever will.
