Remington 11-48 Serial Number Lookup Guide For 2026
Navigating the history of classic American firearms requires precision, and performing a Remington 11-48 serial number lookup is essential for collectors, gunsmiths, and heritage enthusiasts in 2026. The Remington Model 11-48 holds a distinct place in shotgun history as the company's first post-World War II semi-automatic shotgun, replacing the legendary John Browning-designed Model 11. Because Remington manufacturing records from this era can be fragmented, understanding how to decipher receiver stampings, barrel date codes, and sequential production blocks ensures accurate dating and preserves historical value.
Historical Evolution and Design Context of the Remington 11-48
Introduced in 1949 and produced through 1968, the Remington 11-48 revolutionized manufacturing by utilizing stamped steel parts and a streamlined receiver design that departed heavily from the boxy profile of its predecessor. Unlike the Browning-designed Model 11, which relied on a heavy long-recoil system, the 11-48 featured a friction-adjustable ring system on a magazine tube, allowing it to cycle various target and field loads with improved reliability.
Understanding the manufacturing eras helps contextualize where a specific serial number falls. Collectors frequently examine the following structural traits when evaluating an 11-48:
- Receiver Construction: Built using modern stamping and milling techniques to lower production costs and reduce weight.
- Gauge Variations: Manufactured in 12 gauge, 16 gauge, 20 gauge, 28 gauge, and .410 bore, with smaller gauges commanding higher collector interest.
- Sportsman 48 Variant: A three-shot plugged version produced alongside the standard five-shot capacity model to meet migratory bird regulations of the mid-20th century.
- Barrel Interchangeability: Early models featured fixed chokes, while later production runs saw innovations in barrel metallurgy and rib configurations.
Step-by-Step Remington 11-48 Serial Number Location Guide
Locating the serial number on a Remington 11-48 is straightforward once you know where to look. Unlike modern firearms where the serial number is frequently stamped exclusively on the receiver, older Remington shotguns require checking specific structural junctions.
- Safety Inspection First: Always open the action, visually inspect the chamber, and verify the magazine tube is empty before handling the firearm for identification.
- Examine the Receiver Bottom: Locate the serial number stamped directly onto the bottom of the steel receiver, usually positioned just forward of the trigger guard housing.
- Check the Barrel Date Codes: Look on the left side of the barrel just forward of the receiver ring. You will find a two- or three-letter stamp code that corresponds to the month and year of the barrel's manufacture.
- Cross-Reference Internal Components: Inspect the bolt and trigger group for matching assembly numbers, though these do not always match the main receiver serial number on standard field-grade guns.

Decoding Remington Barrel Date Codes vs. Receiver Serials
A common pitfall during a Remington 11-48 serial number lookup is confusing the receiver's sequential serial number with the barrel's cryptic date code. While the receiver serial number tracks the production sequence of the gun, barrels were often manufactured in batches and could occasionally be swapped during the firearm's working life.
| Identification Type | Location on Firearm | Format Example | What It Tells You |
|---|---|---|---|
| Receiver Serial Number | Bottom of receiver near trigger guard | 100000 to 550000+ range | The exact production sequence and relative year manufactured. |
| Barrel Date Code | Left side of barrel near receiver ring | Two or three letters (e.g., "WWW") | The specific month and year the barrel was forged and proof-tested. |
| Proof Marks | Left side of barrel near receiver | Triangle, circle, or "REP" stamp | Factory inspection and high-pressure proof testing verification. |
Remington 11-48 Production Years and Serial Number Ranges
Because Remington's factory archives from the post-war era were partially decentralized, serial number tracking relies heavily on historical factory ledgers preserved by historians and collector associations. The Remington 11-48 serial numbers generally began around the 100,000 range for the 12-gauge variants, though gauges shared overlapping blocks in some production years.
- 1949 (Introduction Year): Serial numbers typically started near 100,000 for standard 12-gauge models, marking the commercial debut of the platform.
- 1950 - 1952: Production expanded rapidly into 16 and 20 gauges, with serial numbers progressing through the 120,000 to 300,000 blocks.
- 1953 - 1957: The introduction of smaller gauges like the 28 gauge and .410 bore occurred within these blocks, highly prized by upland bird hunters.
- 1958 - 1968 (Final Run): Production numbers surpassed the 500,000 threshold, concluding just before Remington fully transitioned its semi-automatic line to newer gas-operated designs like the Model 1100.
Pros and Cons of Owning and Shooting a Remington 11-48
Evaluating whether to restore, collect, or shoot a Remington 11-48 requires weighing its vintage mechanical advantages against modern semi-automatic capabilities.
Advantages
- Classic Craftsmanship: Features deep bluer steel and hand-checkered American walnut stocks absent in modern polymer shotguns.
- Reliable Long-Recoil Heritage: Mechanically robust when the friction rings are properly adjusted for light target loads versus heavy waterfowl magnums.
- Affordable Collector Entry: Generally more budget-friendly than pre-war Browning Auto-5s while offering similar vintage aesthetics.
Disadvantages
- Friction Ring Sensitivity: Incorrectly setting the bronze friction pieces and steel brake rings can batter the receiver or cause failure-to-cycle issues.
- Parts Availability: Factory replacement parts are no longer manufactured by Remington, requiring reliance on secondary collector markets and specialized gunsmiths.
- Steel Shot Incompatibility: Fixed-choke barrels from this era are typically restricted to lead or specialized non-toxic alternatives to prevent bulging the muzzle.
Expert Maintenance and Troubleshooting Tips
Maintaining an 11-48 in 2026 requires understanding its unique friction-delay mechanism. Unlike gas-operated shotguns that bleed off expanding powder gases, the 11-48 utilizes barrel recoil against spring tension.
- Friction Ring Lubrication: Apply a very light coat of high-grade gun oil to the magazine tube. Excess grease attracts unburned powder residue, slowing down the recoil cycle.
- Friction Piece Orientation: For heavy loads, position the tapered edge of the friction ring facing toward the muzzle. For light loads, rearrange the rings so the bronze friction piece rests directly against the magazine spring cap with no brake ring engaged.
- Buffer Pad Inspection: Check the internal receiver shock absorber or friction sleeve periodically to prevent metal-on-metal impact between the barrel ring and receiver housing.
Frequently Asked Questions
How do I find the year of my Remington 11-48?
