Description
The ProMag PM277 turns a plain Marlin 60 or 795 into something a lot more fun to shoot and haul around. It's a side-folding stock molded from tough black polymer, built specifically for these .22 LR Marlin platforms, and it swaps in for the tired old wood or factory synthetic stock most of these rifles came with. Fold it up and the whole rifle collapses down small enough to slide into a medium backpack, which is why folks keep pointing to this thing as the go-to build for a truck gun or pack rifle.
What the PM277 Brings to Your Marlin
The pistol grip gives you a more upright, comfortable hold, and there's a hollow storage compartment inside it for stashing a spare magazine spring, cleaning bits, or small odds and ends. Up front you get a Picatinny tri-rail forend, so mounting a light, laser, bipod, or vertical grip is a screw-and-go affair. The positive locking fold snaps tight and stays put, and you can run the rifle with the stock folded if you want to have some fun mag dumping. A rubber recoil pad rounds it out, though on a rimfire that's more about a solid shoulder feel than soaking up kick.
Fitting the PM277 to a Model 60 or 795
This one covers both the tube-fed Marlin Model 60 (including the old Glenfield 60, which is the same rifle) and the magazine-fed Marlin 795. ProMag includes filler pieces to configure it for whichever one you're running. Most people report the swap taking somewhere in the ten to twenty minute range using basic screwdrivers, and there are no printed instructions in the box, so a little patience and common sense goes a long way. It's a straightforward action-out, action-in job for the 795, while some Model 60 builds may want a touch of trimming for a clean fit.
Made in the USA, the PM277 is a budget-friendly way to breathe new life into a rifle that's been sitting in the safe. It keeps the gun's core function intact while giving you a lighter, more compact, accessory-ready setup.

Frequently Asked Questions
Does the PM277 fit both the Marlin Model 60 and the 795?
Yes, this stock is designed to cover both platforms. It works with the tube-fed Marlin Model 60 (which includes the older Glenfield 60, the same rifle) as well as the magazine-fed Marlin 795 in .22 LR. ProMag includes filler pieces so you can set it up for whichever model you're running.
How hard is the ProMag PM277 to install?
For most people it's a fairly simple swap done with basic screwdrivers, often in the ten to twenty minute range. The 795 tends to be a clean action-out, action-in job, while some Model 60 builds may want a little trimming or sanding around the trigger guard area for a snug fit. There are no printed instructions in the box, so take your time and dry-fit the pieces before final assembly.
Can you shoot the rifle with the PM277 stock folded?
Yes, the rifle can be fired with the stock in the folded position. The positive locking mechanism holds the fold securely, and plenty of owners have a blast running quick strings this way. Just keep in mind you lose your shoulder support and cheek weld when folded, so it's more for fun and compact carry than precision work.
Does the tri-rail forend let me add accessories?
Absolutely. The Picatinny tri-rail forend gives you three rail surfaces up front to mount lights, lasers, a bipod, or a vertical grip. Note that the rails are part of the design and are not meant to be fully removed, so plan your setup around the built-in mounting points.
