The Marlin Model 60 has earned its place as one of the best-selling .22 LR semi-automatic rifles ever made. First introduced in 1960 under the Marlin Firearms Company banner, this tube-fed rimfire rifle has been a staple in American households for decades, with over 10 million units sold during its six-decade production run.
What makes the Model 60 so special is its blend of affordability, reliability, and accuracy. It uses Marlin’s proprietary Micro-Groove rifling—16 shallow lands and grooves instead of the usual 4 to 8 deeper ones found in most rifles. That design choice means less bullet deformation as the round travels down the barrel, and it gives the Model 60 a reputation for being one of the most accurate .22 rifles straight out of the box. The rifle operates on a simple straight blowback action, chambered exclusively for .22 Long Rifle cartridges.
Whether you’re doing routine maintenance, troubleshooting a feeding issue, or replacing a worn-out part, a solid understanding of this rifle’s anatomy makes all the difference. Below, you’ll find a full breakdown of the Marlin Model 60’s key components—what they do, how they work, and why they matter.
Marlin Model 60 Parts Diagram & Details
The provided exploded-view diagram lays out every individual component of the Marlin Model 60 in a disassembled arrangement, with each part numbered and separated from the others so you can clearly see how they relate. Starting from the buttstock and butt pad at the lower left, the diagram moves through the trigger group assembly in the center, up through the receiver and breech bolt area, and finishes at the barrel, front sight, and magazine tube system at the upper right. Small springs, pins, and retaining rings are all accounted for and spaced out so nothing gets lost in the visual.
What’s especially useful about this type of schematic is that it shows you the order of assembly. Parts that sit inside other parts are positioned along logical lines, so you can trace the path from one component to the next. If you’ve ever pulled your Model 60 apart and had a few mystery pieces left over on the workbench, this diagram is your roadmap back to a fully functioning rifle.
Each numbered part in the diagram corresponds to a specific factory component. Let’s walk through the most important ones, explain what they do, and cover a few things worth knowing about each.
1. Stock
The stock is the large hardwood or synthetic body that houses the entire barreled action and gives you something to shoulder when shooting. On most Model 60 variants, it’s a Monte Carlo-style hardwood stock with a pistol grip profile, stained in walnut or birch finishes depending on the production year. Later models also came with synthetic black stocks for added durability and weather resistance.
Your stock attaches to the receiver through front and rear takedown screws, and the trigger guard assembly sits inside a routed channel on its underside. Some later production rifles added a reinforcing wood screw behind the trigger guard to strengthen the wrist area, which is the narrowest and most stress-prone section of the stock. Over years of use, it’s common for this area to develop hairline cracks, especially in hardwood versions.
Beyond aesthetics, the stock plays a critical role in how the rifle points and handles. A warped or damaged stock can throw off your natural aim, so it’s worth inspecting yours periodically for any signs of splitting or looseness around the action screws.
2. Butt Pad and Screws
At the rear end of the stock, you’ll find the butt pad (or buttplate, depending on the model year). Early Glenfield-era rifles from the 1960s and 1970s used a checkered synthetic buttplate, while later Model 60s transitioned to a softer rubber recoil pad. Either version is held in place by two screws that thread directly into the stock.
Because the .22 LR produces almost no felt recoil, the butt pad is less about absorbing kick and more about protecting the end of the stock from dings and providing a non-slip surface against your shoulder. That said, these pads can dry out and crack over the years, especially if the rifle has been stored in a hot attic or a dry gun safe without humidity control.
3. Barrel
The barrel is the long steel tube running from the receiver to the muzzle, and it’s where the magic of Marlin’s Micro-Groove rifling lives. Standard Model 60 barrels measure 19 inches on later models (22 inches on earlier versions), with a 1:16-inch right-hand twist rate. That twist is tuned specifically for .22 LR velocities and bullet weights, giving you tight groups at typical rimfire distances.
One thing that sets the Model 60 barrel apart from competitors is the 16 micro-grooves cut into the bore. Traditional rifling uses fewer, deeper grooves that bite hard into the soft lead bullet. Micro-Groove rifling uses many more shallow grooves that gently grip the projectile, reducing deformation and improving consistency from shot to shot.
The barrel sits in the receiver and is held in place by a barrel retaining pin. On the underside, the outer magazine tube runs parallel to the barrel, secured by a magazine tube band. At the muzzle end, you’ll find the front sight assembly.
4. Barrel Retaining Pin
This small but essential cross pin locks the barrel into the receiver. Without it, the barrel would simply slide out of the front of the receiver during disassembly—or worse, during firing.
When you’re field-stripping the Model 60, the barrel retaining pin is one of the first things you’ll need to push out. A correctly sized punch and a light tap with a hammer are all it takes. Be careful not to lose it, though. It’s small enough to roll off a workbench and vanish into the carpet.
5. Receiver
The receiver is the central aluminum housing that ties everything together. It holds the barrel at the front, the breech bolt assembly inside, and bolts to the stock through the takedown screws. The top of the receiver features a serrated, non-glare finish and is grooved to accept scope mounts—a feature that makes adding optics a straightforward process with no drilling or tapping required.
On the right side of the receiver, you’ll find the ejection port, where spent casings are thrown clear after each shot. The charging handle slot is also cut into the right side. Every receiver has a serial number stamped on it, and post-2009 Remington-manufactured rifles carry a “REP” proof mark on the barrel’s right side.
6. Breech Bolt
The breech bolt is the heart of the action. It’s a rectangular steel block that slides back and forth inside the receiver, stripping cartridges from the feed throat, chambering them, firing them via the firing pin, and then extracting and ejecting the spent casing. The entire cycle happens in a fraction of a second thanks to the simple blowback design.
Mounted on the bolt are the left and right extractors, which grab the rim of the .22 LR casing and pull it rearward after firing. The charging handle fits into a slot on top of the bolt and gives you a way to manually cycle the action. Over time, the bolt face can accumulate carbon and lead residue, so regular cleaning with a nylon brush and solvent will keep it running smoothly.
The bolt’s mass is what regulates the timing of the blowback cycle. Since there’s no locking mechanism, the bolt’s weight alone holds the breech closed long enough for the bullet to exit the barrel and pressure to drop to safe levels.
7. Charging Handle
The charging handle is a small, knurled metal piece that protrudes from the top-right of the receiver when the bolt is in battery. You pull it rearward to manually retract the bolt, which compresses the recoil spring and lets you load the first round from the magazine.
On the Model 60, the charging handle also doubles as a manual bolt hold-open. You can pull it all the way back and push it into a small notch in the receiver to lock the bolt in the open position. This is handy for visual safety checks at the range or when you need to clear a jam.
8. Firing Pin and Retaining Pin
Housed inside the breech bolt, the firing pin is a slender steel rod that strikes the rim of the .22 LR cartridge to ignite the primer compound. Unlike centerfire rifles that use a spring-loaded firing pin, the Model 60’s firing pin is driven forward by the hammer’s impact and held in place by a small cross pin called the firing pin retaining pin.
If your Model 60 starts producing light strikes or misfires, the firing pin is one of the first components to inspect. A chipped or worn tip, or a damaged retaining pin, can cause unreliable ignition. Replacement firing pins are inexpensive and relatively easy to swap with basic tools.
9. Extractors (Left and Right)
The Model 60 uses a dual extractor system—one on each side of the bolt face. These small, spring-loaded hook-shaped pieces grab the rim of the .22 LR cartridge on both sides, ensuring a firm and even grip during extraction. Each extractor has its own spring and retaining pin.
Having two extractors instead of one gives the Model 60 a more reliable extraction cycle, which is part of why this rifle has a reputation for running well even with bargain-bin bulk ammo. That said, the extractor springs can weaken over thousands of rounds. If you notice spent casings failing to eject or stovepiping at the ejection port, worn extractors or their springs are the likely culprit.
10. Feed Throat
The feed throat is a small, shaped metal piece that sits at the rear of the receiver and guides cartridges upward from the cartridge lifter into the chamber. It’s positioned so that as the bolt travels forward, it picks up the top round and pushes it smoothly into the barrel’s chamber.
Getting the feed throat properly seated during reassembly is critical. It has locating studs (two or three, depending on the model year) that must align with corresponding holes in the receiver. A misaligned feed throat is one of the most common causes of feeding failures after a detail strip.
11. Cartridge Lifter and Roller
Working in tandem with the feed throat, the cartridge lifter is a spring-loaded lever that raises each round from the magazine tube up to the bolt’s path. Sitting at the tip of the lifter is a small roller—a tiny cylindrical piece that reduces friction as the cartridge slides across the lifter’s surface.
The lifter is activated by the bolt’s rearward movement. As the bolt recoils after firing, it pushes the lifter down, allowing a fresh round to be released from the inner magazine tube. When the bolt moves forward again, the lifter rises and presents the cartridge in position for the bolt to strip it into the chamber.
If the roller goes missing or the lifter spring loses tension, you’ll notice feeding issues almost immediately. Rounds may fail to present properly, or you’ll get double feeds. Checking the lifter and its roller should be part of any thorough cleaning session.
12. Hammer
The hammer is a pivoting steel component housed inside the trigger guard assembly. When you pull the trigger, the hammer is released from its cocked position, swings forward under spring pressure, and strikes the rear of the firing pin to discharge the round.
On the Model 60, the hammer also serves as the mounting point for the hammer strut—a connecting rod that transfers the force of the compressed hammer spring into rotational energy. The hammer pin, which the hammer pivots on, passes through the sides of the trigger guard housing and is retained by a small pin ring.
13. Hammer Spring, Strut, and Strut Bridge
The hammer spring is a coiled compression spring that stores energy when the bolt cycles rearward and cocks the hammer. This energy is released when the trigger lets the hammer go. Connected to the hammer by the hammer strut—a metal rod—the spring pushes against the strut bridge, a small anchor piece that sits at the bottom of the trigger guard assembly.
Together, these three parts form the power system behind every shot. A weak or broken hammer spring leads to light primer strikes, which means misfires. This is one of the more common wear items on high-round-count Model 60 rifles, and aftermarket trigger spring kits are widely available for owners who want crisper trigger pull and more reliable ignition at the same time.
14. Trigger and Disconnector
The trigger is the part you actually press to fire the rifle. In the Model 60, it’s a curved metal lever that pivots inside the trigger guard assembly. Pulling it releases the hammer sear, allowing the hammer to swing forward. Some production years featured chrome-plated metal triggers, while later runs used polymer triggers.
Working alongside the trigger is the disconnector, a separate spring-loaded part that prevents the hammer from following the bolt forward and firing again before the bolt is fully closed. The disconnector catches the hammer as the bolt returns to battery, holding it in the cocked position until you release and re-pull the trigger. Without a functioning disconnector, the rifle could slam-fire—a dangerous malfunction where rounds fire uncontrollably as the bolt cycles.
The disconnector spring sits nearby in the trigger assembly and keeps the disconnector under proper tension. All three parts—trigger, disconnector, and disconnector spring—need to work together precisely for safe, reliable operation.
15. Trigger Guard Assembly
The trigger guard assembly is the metal housing that contains the trigger, hammer, disconnector, sear components, and their associated springs and pins. On the Model 60, this entire assembly is designed to stay in the stock when the barreled action is removed, making field disassembly faster and simpler.
Mounted to the stock with a front screw (which threads into a trigger guard nut) and either a rear screw or pin depending on the model year, the trigger guard also features the cross-bolt safety and—on later models—the bolt release lever. Mid-1980s and newer rifles have an automatic last-shot bolt hold-open mechanism built into the guard, which locks the bolt open after the last round is fired.
16. Cross-Bolt Safety
Located just above and behind the trigger, the cross-bolt safety is a small button that slides from side to side through the trigger guard assembly. Pushing it to one side blocks the trigger from being pulled, while pushing it back to the other side puts the rifle in the fire position. A visible red indicator typically shows when the rifle is ready to fire.
It’s a simple, reliable safety mechanism that’s easy to operate with your trigger finger or thumb without removing the rifle from your shoulder. Like all mechanical safeties, though, it should be treated as a backup—not a substitute for safe muzzle discipline and proper handling.
17. Bolt Release Lever
Found in the front of the trigger guard on post-mid-1980s Model 60 rifles, the bolt release lever allows you to release the bolt from its hold-open position. After the last round is fired, the automatic bolt hold-open locks the action open as a visual indicator that the magazine is empty. Pressing the bolt release lever drops the bolt forward.
Earlier Model 60s and Glenfield-era rifles didn’t have this feature. On those, you manually lock the bolt open with the charging handle, and release it the same way.
18. Buffer
The buffer is a small synthetic block—usually white or black plastic—that sits at the rear of the bolt’s travel path inside the receiver. Its job is to absorb the impact of the bolt slamming rearward during the blowback cycle, cushioning the blow and preventing metal-on-metal contact between the bolt and the receiver.
This is arguably the most commonly replaced part on the entire rifle. Because the buffer is made of plastic, it dries out, cracks, and crumbles over time, especially on older rifles. A disintegrated buffer can jam the action, and pieces of broken plastic can wind up in places they shouldn’t be. Replacements are cheap—usually just a few dollars—and swapping one in requires removing the stock and action assembly. It’s a smart idea to keep a spare on hand.
The buffer is retained in position by the buffer pin ring, a small C-shaped metal clip that holds the buffer pin in place within the receiver.
19. Recoil Spring and Guide
The recoil spring is a long coiled spring that wraps around a metal guide rod. Together, they sit inside the receiver and run beneath the bolt assembly. When the bolt flies rearward after a shot, it compresses the recoil spring. That stored energy then pushes the bolt forward again to strip and chamber the next round.
A worn-out recoil spring can cause short-stroking—where the bolt doesn’t travel far enough rearward to pick up a new round or fully eject the spent casing. It can also cause sluggish cycling or failure to return fully to battery. If your Model 60 starts running unreliably and cleaning doesn’t fix it, the recoil spring is worth checking.
20. Inner Magazine Tube Assembly
The inner magazine tube is the heart of the Model 60’s ammunition feeding system. It’s a long, spring-loaded tube that sits inside the outer magazine tube beneath the barrel. You load cartridges by pulling the inner tube out from the front of the rifle, dropping rounds into the outer tube, and then sliding the inner tube back in. The spring-loaded follower inside the inner tube pushes the cartridges rearward toward the action.
Depending on the production year, the Model 60 holds either 14 or 17 rounds of .22 LR. Earlier 22-inch barrel versions held more rounds due to the longer magazine tube, while the shorter 19-inch barrels reduced capacity. The inner tube includes a follower at its tip that maintains constant spring pressure on the cartridge column.
If the inner tube’s spring loses its tension or the follower becomes bent, rounds won’t feed reliably. It’s one of those parts that usually works perfectly for years until it suddenly doesn’t—at which point a full replacement tube assembly is the best fix.
21. Outer Magazine Tube and Band
The outer magazine tube is the fixed steel tube that runs beneath and parallel to the barrel, providing the housing through which cartridges sit in line, waiting to be fed into the action. It’s permanently attached to the receiver at the rear and supported at the front by the magazine tube band—a metal clamp secured by a small band pin.
The outer tube rarely needs replacement unless it’s been dented or damaged from a drop. The magazine tube band, however, can sometimes loosen over time, which may introduce a slight rattle or allow the outer tube to shift. A quick check of the band pin and a light tightening during routine maintenance will keep everything solid.
22. Front Sight Assembly
At the muzzle end of the barrel, the front sight assembly consists of a ramp base, a small interchangeable sight insert (typically a brass bead), and a protective hood that shields the sight from glare and accidental damage. The ramp base is secured to the barrel with a screw, and the hood simply slips over the top.
For target shooting or hunting small game, the factory front sight works well at typical .22 LR distances. Many owners do upgrade to fiber optic inserts for better visibility in low light. If you’re mounting a scope, the front sight can be left in place since it sits low enough to not interfere with most optic setups.
23. Rear Sight Assembly
Mounted on top of the barrel a few inches forward of the receiver, the rear sight is an adjustable open sight with an elevation slider (or “elevator”) that lets you raise or lower your point of impact. It’s held in place by two small screws—one front, one rear—and can be removed entirely if you switch to a scope.
The rear sight on the Model 60 is a semi-buckhorn style that provides a clear sight picture when paired with the front bead. Windage adjustments require drifting the sight left or right in its dovetail, while elevation is handled by the stepped elevator piece. It’s a no-frills sighting system, but it’s effective and durable.
24. Ejector/Lifter Spring
This small but vital spring provides the tension needed for the ejector mechanism to kick spent casings out of the ejection port and for the cartridge lifter to properly present fresh rounds. It lives inside the trigger guard assembly area and connects to the lifter mechanism.
A broken or weakened ejector/lifter spring usually shows up as erratic ejection—casings dribbling out the side of the receiver instead of being thrown clear, or spent cases bouncing back inside and jamming the action. Replacement springs are inexpensive and can be fitted with basic gunsmithing tools.
25. Takedown Screws (Front and Rear)
The front and rear takedown screws are what hold the barreled receiver in the stock. The front screw sits in the forearm area beneath the barrel and threads into a nut inside the stock. The rear screw passes through the trigger guard and secures the action at the wrist of the stock.
To field-strip the Model 60, you remove both takedown screws, and the barreled action lifts out of the stock—leaving the trigger guard assembly behind in the wood. These screws have gone through several variations over the years, including slotted, Phillips, and Torx head styles. Whatever type yours uses, avoid overtightening them, as the wood or synthetic stock material can crack under too much pressure.
