Rifle Magazine Inspection and Cleaning Guide

Picture this: opening morning, first light, a doe steps into the clearing 80 yards out. You chamber a round from your Remington 783's magazine and the bolt hangs up halfway, the cartridge nose-diving into the magazine well instead of feeding straight. By the time you clear it, she's gone. That failure almost never comes from a bad barrel or cheap ammo. It comes from a magazine that hasn't been pulled apart and cleaned since the day it left the box.

Detachable box magazines are simple machines with a handful of moving parts, but they run in the dirtiest environment on the rifle — down in the mag well, exposed to rain, mud, pocket lint, and the grit that collects in a range bag. A few minutes of inspection and cleaning before and after every season is the cheapest reliability upgrade you can make to a Marlin or Remington 783. This guide walks through exactly how to do it, part by part.

Why Magazine Maintenance Matters More Than You Think

Most shooters clean the bore, wipe down the bolt, and oil the action, then drop the magazine back in without a second look. That's backwards. The magazine is what feeds every round you fire, and it's the part most exposed to field conditions: it rides against your pocket, gets set on the ground during a reload, and picks up grit every time it's pulled from a pack.

A magazine that's never cleaned accumulates a fine layer of carbon dust, pocket lint, and dirt along the spring coils and follower rails. That buildup doesn't cause a dramatic failure right away — it causes a slow one. The follower starts riding unevenly, cartridges feed a fraction of a second late, and under field pressure that fraction of a second is the difference between a clean shot and a jam.

In a working gunsmith shop, magazine-related stoppages account for a large share of the "my rifle won't feed right" complaints that come through the door — and in the overwhelming majority of those cases, the barrel, extractor, and chamber are fine. The fix is a magazine teardown, not a trip to the bench grinder. If you want the full rundown on keeping the rest of a Marlin running alongside its magazines, see our guide on taking care of your Marlin rifle.

The Anatomy of a Detachable Box Magazine

Before you can inspect a magazine intelligently, you need to know what you're looking at. Every Marlin rimfire and Remington 783 centerfire detachable magazine breaks down into four parts: the body (the metal or polymer shell), the follower (the platform that pushes cartridges up), the spring, and the floorplate (the removable base that holds the spring under tension).

The feed lips — the two curved edges at the top of the body — are the most critical and most overlooked part of the entire assembly. They control the angle at which each round releases into the chamber. Even a small amount of deformation here causes double-feeds, failure to feed, or a cartridge that noses down instead of riding up smoothly.

• Body: houses the stack of cartridges and guides the follower
• Follower: rides up the body under spring pressure, pushing the top round into the feed lips
• Spring: provides the upward pressure; fatigue here is gradual and easy to miss
• Floorplate: locks the spring in place and is almost always the entry point for disassembly

Knowing these four parts by name makes the rest of this process faster, because every inspection step below refers back to one of them specifically.

When to Inspect: Building a Real Maintenance Schedule

Inspection frequency should match how hard the magazine works, not a calendar reminder you'll ignore. A magazine that lives in a safe and comes out twice a year needs a check before each outing. A magazine you carry in a truck console or hunting pack all season needs monthly attention even between range trips.

As a working rule: strip and clean every magazine after 2-3 range sessions of normal use, and immediately after any outing involving rain, snow, mud, or sand — regardless of how many rounds you fired. Dirt doesn't care how many rounds went downrange; it cares how many times the magazine touched the ground.

Before hunting season opens, every magazine that will ride in the rifle should get a full teardown, not a wipe-down. That's also the right time to function-test with dummy rounds, described later in this guide, so you're not discovering a feed problem on opening morning.

Between cleanings, store magazines loaded to one or two rounds under capacity rather than topped off for months at a time — this reduces long-term spring set. For rimfire-specific storage habits, including how humidity affects .22LR and .22WMR magazines differently, see our rimfire magazine care and storage guide.

Step-by-Step: Disassembling a Marlin Rimfire Magazine

Marlin rimfire magazines built for detachable-box rifles — the 795 chief among them — use a simple floorplate-and-spring design. To disassemble one: unload it fully, depress the floorplate release (usually a small tab or pin at the base), and slide the floorplate off the body. The spring and follower will come out from the bottom; note the follower's orientation before it comes free so reassembly is straightforward.

The Marlin 795 runs a 7- or 10-round .22LR magazine. The original factory magazine is the 71900, with the 71901 as a running production update, and ARM also produces two 10-round .22LR variants built to the same factory-correct dimensions — not aftermarket knockoffs, but magazines made to the original spec.

One caution that matters more here than almost anywhere else: a .22WMR or .17HMR magnum magazine will not feed .22LR reliably, and the two should never be swapped or treated as interchangeable. The case dimensions differ enough that a magnum-pattern magazine loaded with .22LR ammunition will feed poorly or not at all — if you're not sure which chambering your magazine is built for, check your rifle and match the model number to the caliber printed on the product listing before you clean, load, or shoot it.

To find your model number, look on the left side of the barrel — Marlin stamps it there — then match that number to the magazine description on the product page before ordering a replacement or spare.

Step-by-Step: Disassembling a Remington 783 Magazine

Remington 783 magazines are polymer-bodied and use a similar floorplate release, though the tab sits at the rear of the base rather than underneath. Unload the magazine, press the release tab, and slide the floorplate rearward off the body. The spring and follower lift out from the open end.

Body length on the 783 varies by chambering, and it's worth knowing the difference before you order a spare or troubleshoot a feed issue. Magnum-length bodies, built for cartridges like .300 Winchester Magnum and 7mm Remington Magnum, are the longest of the three body lengths and hold 3 rounds. Long-action bodies, for .30-06, .270 Winchester, and .25-06, are shorter than the magnum body and hold 4 rounds. Short-action bodies, for chamberings like .308 Winchester and 6.5 Creedmoor, are shorter still — for the exact round count on a short-action magazine, check the model callout on the product page or your rifle's manual rather than assuming.

Because these three body lengths look similar at a glance, cross-checking your rifle's model number against the caliber listed on the product page before you buy or clean a spare avoids the single most common mix-up we hear about from 783 owners. For a full length-by-length breakdown, see our guide on Remington 783 short-action vs. long-action magazines.

Cleaning Process: Tools and Technique That Actually Work

You don't need a gunsmith's bench to clean a magazine correctly — you need five minutes, a soft-bristle brush, a dry microfiber cloth, cotton swabs, and a light gun oil. Skip the solvent bath. Dunking a magazine in solvent strips whatever coating protects the metal and leaves the spring coils wet, which attracts dust the moment you load it again.

With the magazine fully disassembled, brush loose debris out of the body first, paying attention to the corners where the follower rides — that's where lint and grit pack tightest. Wipe the spring down its full length with a dry cloth to remove carbon and dust, then check each coil for gaps or kinks as you go.

Clean the follower with a swab, checking the rails on its sides for buildup that would make it bind against the body. Wipe the inside of the floorplate and the feed lips last, using a cloth wrapped around a fingertip to reach the curved edges without scratching them.

Once every part is dry, apply a single drop of gun oil to a cloth and wipe — not spray — a thin film onto the spring and the follower rails only. A heavy coat does more harm than good: excess oil becomes a dirt magnet in the field. Reference our general rifle cleaning guide for the same light-touch approach applied to the rest of the gun.

Spotting Wear: What to Look For Before Reassembly

Cleaning removes dirt; inspection catches damage that cleaning won't fix. Run through each part with a critical eye before you put the magazine back together, because a worn part loaded back into a clean body is still a worn part.

Check the feed lips first by comparing them side to side — they should be symmetrical and hold consistent inward tension. If one side flexes noticeably more than the other, or if you can see daylight unevenly around a chambered dummy round, the lips have started to spread and the magazine's feed reliability is compromised.

Next, check the follower for cracks, especially around the tilt point where it contacts the feed lips. Then check the spring: compress it fully and hold it for 24 hours; if it doesn't return to its original length when released, it's fatigued and due for replacement.

• Feed lips: uneven tension or visible spreading means reduced reliability
• Follower: hairline cracks or a rough, binding travel path
• Spring: doesn't rebound fully after 24 hours under compression
• Body finish: surface rust or pitting, especially on carbon-steel bodies

Surface corrosion on steel-bodied magazines is worth catching early — light surface rust can usually be cleaned off, but pitting means the finish has already failed. For a breakdown of which finish holds up better in which conditions, read our comparison of black oxide vs. nickel magazines.

Reassembly and Function Testing

Reassembly is the reverse of disassembly, but the order matters. Seat the follower into the body first, oriented the same way it came out, then compress the spring underneath it and slide the floorplate back on until the release tab clicks into place. If the floorplate won't seat flush, stop — something is misaligned inside, and forcing it risks cracking the body.

Once assembled, run a function test with 3-5 dummy rounds (snap caps or inert cartridges, never live ammunition, for this check). Load the magazine fully and cycle each round through the action by hand, watching how it releases from the feed lips. It should ride straight up and feed in a smooth arc without catching or nose-diving.

Load the magazine to capacity and let it sit overnight, then unload it and check that the follower still moves freely — this catches spring or follower binding that a quick test might miss. A magazine that passes both the dummy-round cycle test and the overnight load test is field-ready.

Do this test on every magazine before hunting season opens, not just the one currently in the rifle. A spare that jams on opening morning is worse than no spare at all, because you won't find out until you need it.

Common Mistakes That Wear Out Magazines Early

The most common mistake is storing a magazine fully loaded for months at a time. Constant full compression accelerates spring set, and a magazine that's always topped off will lose reliable feed tension years before one that's occasionally unloaded and rested.

The second most common mistake is over-oiling. Shooters who spray a magazine down the same way they'd oil a bolt end up with a follower that slides through a film of sticky lubricant mixed with range dust — worse than running it dry. Light oil on the spring and follower rails only, wiped on with a cloth, is enough.

Third: forcing a magazine that doesn't seat. If a magazine feels tight going into the well, don't force it — pull it back out and check for a bent feed lip or debris in the well itself. Forcing a damaged magazine into place can crack the mag well or bend the floorplate release.

Fourth, and specific to rimfire owners: assuming a magazine will interchange across calibers because it looks similar. A .22WMR or .17HMR magazine and a .22LR magazine are not interchangeable, and treating them as such is a fast way to bend feed lips on both. Fifth, if you're building out a stock of spares for a household or a small shop, check your state's rules before ordering higher-capacity magazines — verify current law in your state rather than assuming capacity limits are uniform nationwide.

Storage Between Cleanings

How a magazine sits between range trips matters almost as much as how you clean it. Store magazines in a dry environment — a safe with a dehumidifier rod or a closet away from a damp basement — rather than a garage where humidity swings with the weather. Moisture is the single biggest driver of the surface corrosion that shows up on steel-bodied magazines.

Keep magazines separated by caliber and model, especially if you own both a Marlin rimfire and a Remington 783. Magazines that look similar in a drawer are easy to grab by mistake, and loading the wrong one, even briefly, can bend feed lips that were never designed for that cartridge.

Label spares by model number, matched to the same number stamped on the left side of your barrel, so there's no guesswork when you reach for one in low light on opening morning. A strip of tape and a permanent marker on the floorplate takes ten seconds and saves a fumbled reload later.

Rotate spares into occasional use rather than leaving one magazine in the rifle year-round and the rest untouched in a drawer. A magazine that sits loaded and unused for a year is more likely to have spring set and unnoticed corrosion than one that gets cycled through cleaning and function testing on a normal rotation.

Put This Into Practice Before Your Next Range Trip

A clean, inspected magazine is the cheapest reliability upgrade on the rifle, and it takes less time than a single trip through a car wash. Pull every magazine you own — not just the one currently loaded — strip it down this week, and run the dummy-round function test before you load live ammunition again.

If inspection turns up spread feed lips, a cracked follower, or a spring that won't rebound, replace the magazine rather than fighting it through another season. Check the model number on the left side of your barrel, match it to the correct listing, and order a factory-correct replacement built for your exact rifle and caliber.
