Remington Model 11-48 Serial Number Lookup And Production Dating Guide 2026
The Remington Model 11-48 represents a significant milestone in American firearm engineering as the company's first successful semi-automatic shotgun utilizing a long-recoil action after the Second World War. For collectors, gunsmiths, and enthusiasts operating in 2026, accurately identifying the manufacture date is essential for maintenance, parts compatibility, and historical valuation.
Understanding the Remington 11-48 Production Era
The Model 11-48 was produced between 1949 and 1968. It was designed to replace the earlier Model 11 and the Sportsman, offering a streamlined receiver and improved reliability. Because Remington utilized a specific barrel code system rather than a dedicated serial number database accessible via a public digital lookup tool, identifying your firearm requires a combination of physical inspection and cross-referencing known factory marking patterns.
In 2026, the primary method for dating these firearms remains the "Barrel Code" system. While serial numbers are stamped on the receiver, they provide limited chronological data on their own due to inconsistent factory record-keeping during the post-war transition period. The two-letter code located on the left side of the barrel, just forward of the receiver, is the gold standard for dating.
Locating and Deciphering Barrel Date Codes
To determine the production year of your Remington 11-48, you must examine the left side of the barrel, near the breech. You will find a two-letter or three-character stamp. The first letter represents the month of manufacture, and the subsequent letters represent the year.
The following table serves as a reference for deciphering the year codes used by Remington during the production run of the Model 11-48.
| Letter Code | Corresponding Year |
|---|---|
| WW | 1949 |
| XX | 1950 |
| YY | 1951 |
| ZZ | 1952 |
| A | 1953 |
| B | 1954 |
| C | 1955 |
| D | 1956 |
| E | 1957 |
| F | 1958 |
| G | 1959 |
| H | 1960 |
| J | 1961 |
| K | 1962 |
| L | 1963 |
| M | 1964 |
| N | 1965 |
| P | 1966 |
| R | 1967 |
| S | 1968 |
Note that codes can occasionally overlap or appear ambiguous due to factory restamping. If your barrel has been replaced—a common occurrence given the long service life of these shotguns—the date code will reflect the date the barrel was produced, not necessarily the date the receiver was assembled.

Technical Specifications and Maintenance Priorities
The Model 11-48 utilizes a friction ring system to manage recoil. Proper configuration of this system is critical for both the longevity of the shotgun and the safety of the shooter. In 2026, many owners face issues with improper friction ring setups when transitioning between high-brass and low-brass ammunition.
Operational Configuration Requirements
Friction Ring Orientation When shooting heavy field loads, ensure the friction ring is positioned with the tapered side facing the barrel ring. For light target loads, the tapered side must face the receiver to increase friction and slow the bolt carrier velocity. Failure to adjust this correctly can result in excessive wear on the receiver or, in extreme cases, a cracked forend.
When servicing a Model 11-48 in 2026, source parts specifically designated for the 11-48. While some parts are shared with the Model 870 or the older Model 11, the 11-48 internals are unique. Avoid using modern synthetic greases on the magazine tube; instead, use a light coat of high-quality, cold-weather gun oil. Over-lubrication attracts carbon buildup, which causes short-cycling in the long-recoil action.
Distinguishing Receiver Serial Numbers
While the barrel code is the primary dating tool, the serial number stamped on the bottom or side of the receiver is vital for identifying the specific production series. Remington 11-48 serial numbers generally do not follow a sequential, easily searchable format.
If you are researching a serial number for internal inventory or historical tracking in 2026, observe these guidelines:
- Check the bottom of the receiver for the serial number.
- If the shotgun was produced for specific government or police contracts, an "S" or "V" prefix may appear, though these are rare on standard civilian models.
- If the serial number is obscured by heavy finish wear or pitting, do not attempt to etch or remove material to reveal it, as this may be classified as a legal violation under federal regulations regarding firearm defacement.
Comparative Overview: Model 11-48 vs. Modern Semi-Autos
Collectors often compare the 11-48 to modern platforms like the V3 or Versa Max. The following comparison highlights why the 11-48 remains a specialty interest item in 2026 rather than a primary tactical choice.
| Feature | Remington 11-48 | Modern Semi-Auto (2026 Standard) |
|---|---|---|
| Operating System | Long-Recoil | Gas-Operated / Inertia |
| Recoil Management | Manual Friction Ring | Self-Regulating Valves |
| Material | Machined Steel | Aircraft-Grade Aluminum / Polymer |
| Maintenance | High (Requires frequent cleaning) | Low (Extended service intervals) |
| Parts Availability | Obsolete (Secondary Market Only) | High (Current OEM support) |
Frequently Asked Questions regarding 11-48 Identification
Can I look up my serial number on the official Remington website in 2026? No. Remington's current corporate structure does not maintain a public-facing digital lookup tool for legacy serial numbers from the 1949-1968 era. You must rely on the barrel date code system described above to determine the age of your firearm.
What should I do if my barrel has no visible date code? A missing date code usually indicates that the barrel has been polished for a re-blue or has been replaced with an aftermarket barrel that was never stamped. In this case, the firearm cannot be dated accurately via manufacturer markings.
Are Model 11-48 shotguns safe to use with modern steel shot? Most 11-48 barrels are choked full or modified and are not designed for modern steel shot, which can score the barrel steel. Use bismuth or tungsten-matrix non-toxic loads if you intend to hunt waterfowl with this firearm in 2026.
Does a high serial number mean the shotgun is more valuable? Generally, no. Value for the Model 11-48 is driven more by condition, originality, and the presence of special features (such as vent ribs or rare barrel lengths) rather than the serial number sequence.
How do I safely verify if my shotgun is unloaded? Always visually and physically inspect the chamber and magazine tube. With the action locked open, check the chamber, then depress the carrier to ensure the magazine follower is visible and no shells are present in the tube.
Final Guidance for Owners
The Remington Model 11-48 is an heirloom-quality firearm that requires a refined touch. In 2026, the most responsible path for owners is to prioritize the preservation of the original factory finish and to document the barrel date code in a personal logbook. If you are uncertain about the structural integrity of your specific receiver due to age, consult a certified gunsmith who specializes in long-recoil systems before firing. By maintaining the friction ring system correctly and using appropriate ammunition, you ensure the mechanical longevity of this classic American shotgun for years to come.
