Remington Model 11 48 Serial Number Lookup Guide For 2026
Navigating a Remington Model 11 48 serial number lookup in 2026 requires understanding the manufacturing history of one of Remington's most iconic post-World War II semi-automatic shotguns. Produced from 1948 until 1968, the Model 11-48 represented a significant leap forward in firearm manufacturing, transitioning from the heavy, long-recoil Browning Auto-5 design to a streamlined, lightweight design utilizing a modern steel receiver and a friction-ring operating system. For collectors, hunters, and firearm enthusiasts today, accurately dating this classic firearm depends on decoding factory stampings, barrel codes, and specific serial number ranges.
Historical Context and Engineering Evolution of the Remington 11-48
The Remington Model 11-48 was introduced immediately after the conclusion of World War II, replacing the older Model 11, which was essentially a licensed production of the John Browning-designed Auto-5. The 11-48 introduced a hydro-formed steel receiver that featured a distinctive profile, tapering smoothly toward the rear. This design not only reduced the overall manufacturing cost and weight of the shotgun but also improved handling dynamics compared to its predecessor.
Understanding the production lineage is essential for collectors performing a serial number lookup. The shotgun was offered in multiple gauges, including 12, 16, 20, 28, and .410 bore. Each gauge variant possesses distinct mechanical nuances, particularly regarding the adjustment of the friction rings for light versus heavy loads. Collectors often look for specialized variants, such as the Remington "Sportsman-48," which was a three-shot capacity version produced to comply with federal migratory bird hunting regulations of the era.
Decoding Remington Serial Numbers and Barrel Codes
Unlike modern firearms that feature strict sequential serial numbers governed by standardized federal databases, mid-20th-century firearms like the Remington 11-48 rely heavily on a combination of receiver serial numbers and barrel date codes. Because Remington frequently interchanged parts or assembled guns from stockpiled components, the receiver serial number may sometimes reflect a slightly different year of final assembly than the barrel stamping.
Receiver serial numbers for the Model 11-48 are typically located on the bottom of the receiver forward of the trigger guard. Depending on the production year, these numbers may or may not be preceded or followed by a letter prefix or suffix that designates the gauge or specific manufacturing block. However, Remington's factory records from this era are notoriously incomplete due to corporate record shifts and fires over the decades. Consequently, firearm historians rely heavily on the barrel code system alongside serial number ranges.
Barrel codes are stamped on the left side of the barrel just forward of the receiver. They consist of a two- or three-letter combination where the first letter represents the month of manufacture and the remaining letters represent the year. Cross-referencing these barrel codes with estimated serial number blocks provides the most accurate dating methodology available to collectors in 2026.

Step-by-Step Remington Model 11 48 Identification Process
Executing an accurate lookup of a Remington Model 11 48 requires a methodical physical inspection of the firearm. Follow this structured process to determine the production timeline and configuration of your shotgun:
- Safety Verification: Ensure the firearm is completely unloaded by opening the action, inspecting the chamber, and checking the magazine tube. Never rely solely on memory; physically and visually verify the state of the firearm before handling.
- Locate the Receiver Serial Number: Turn the shotgun upside down and examine the lower frame forward of the trigger assembly housing. Record the full alphanumeric string exactly as stamped.
- Inspect the Barrel Markings: Look at the left side of the barrel near the receiver joint. Identify the stamped letters that indicate the production month and year.
- Determine the Gauge and Model Variant: Check the barrel roll-mark to verify the chamber size (e.g., 2-3/4 inch) and gauge. Inspect the magazine capacity and receiver markings to distinguish between a standard Model 11-48 and a Sportsman-48 variant.
- Evaluate Mechanical Condition: Assess the integrity of the wooden stock, the bluing on the receiver and barrel, and the functionality of the friction ring system on the magazine tube.

Expert Maintenance and Troubleshooting Tips for Vintage Shooters
Maintaining a vintage Remington Model 11-48 in 2026 requires careful attention to its operating principles. Because it is a long-recoil operated shotgun, the positioning of the friction rings and bronze friction piece on the magazine tube dictates how the firearm cycles varying ammunition loads.
- Friction Ring Configuration for Heavy Loads: When shooting high-brass or heavy waterfowl loads, position the tapered bevel of the friction ring facing toward the muzzle, with the bronze friction piece placed inside the spring. This increases friction against the magazine tube, slowing down the rearward velocity of the barrel and bolt to prevent receiver damage.
- Friction Ring Configuration for Light Loads: When shooting low-brass target loads or light field loads, reverse the friction ring so the bevel faces toward the receiver, or remove the friction ring entirely depending on the specific gauge and load manual specifications.
- Magazine Tube Lubrication: Keep the magazine tube clean and lightly lubricated with a high-grade gun oil. Excessive grease or complete dryness will cause cycling failures. The tube must be free of carbon fouling to allow the barrel ring to recoil smoothly.
