Over / under shotguns use two vertically stacked barrels in a break-action configuration. They are widely used for upland hunting, clay-target sports, trap, skeet, sporting clays, competition, recreational shooting, and collecting. Models range from practical field guns to highly refined competition shotguns with adjustable stocks, extended choke systems, premium wood, and specialized barrel configurations.

Over / Under Shotguns

An over / under shotgun places one barrel above the other in a hinged break-action design. Opening the action exposes both chambers for loading, unloading, and inspection. Trigger system, barrel selection, extraction, ejection, safety, and choke configuration vary by manufacturer.

Choosing an Over / Under Shotgun

• Intended Use: Consider upland hunting, field use, trap, skeet, sporting clays, competition, recreational shooting, or collecting.
• Gauge: Compare 12 gauge, 20 gauge, 28 gauge, .410 bore, and other available configurations.
• Barrel Length: Barrel length influences overall balance, swing, weight, sighting plane, and intended sporting application.
• Stock Fit: Compare length of pull, drop, cast, comb height, grip style, recoil pad, and adjustability.
• Chokes: Verify fixed or interchangeable choke configuration and exact manufacturer compatibility.

12 Gauge Over / Under Shotguns

12 gauge over / under shotguns are widely used for sporting clays, trap, skeet, upland hunting, recreational shooting, and competition. Barrel length, chamber size, stock design, and overall weight vary substantially among models.

20 Gauge Over / Under Shotguns

20 gauge models are popular for upland hunting, field use, recreational shooting, and clay-target sports. They are often offered on smaller or lighter frames than comparable 12 gauge models.

28 Gauge Over / Under Shotguns

28 gauge over / under shotguns are popular among upland hunters and clay shooters who prefer the handling characteristics of smaller gauge sporting guns.

.410 Bore Over / Under Shotguns

.410 bore over / under models are available for recreational shooting, clay-target applications, lawful hunting, and collecting. They may be built on compact frames with relatively light overall weight.

Multi-Gauge Sporting Sets

Some premium or competition shotgun packages may include manufacturer-matched barrel sets, sub-gauge configurations, or other multi-gauge arrangements. Exact compatibility should be confirmed from the manufacturer.

Field Over / Under Shotguns

Field guns generally emphasize manageable weight, practical barrel lengths, traditional stock dimensions, durable finishes, and balance suitable for hunting.

Upland Shotguns

Upland over / unders may be configured for extended field carry and fast handling. Wood quality, engraving, receiver size, barrel length, and weight vary from practical working guns to premium sporting models.

Sporting Clays Shotguns

Sporting clays models may use longer barrels, adjustable stocks, extended choke tubes, ported or non-ported barrels, competition-oriented triggers, and increased overall weight.

Trap Shotguns

Trap-oriented over / under shotguns may feature specialized stock dimensions, high ribs, adjustable combs, longer barrels, and other features designed around the requirements of clay-target sports.

Skeet Shotguns

Skeet configurations may use barrel lengths, stock dimensions, chokes, and balance characteristics selected for the discipline. Exact competition requirements vary.

Competition Over / Under Shotguns

Competition shotguns can incorporate refined triggers, adjustable stocks, interchangeable chokes, high or adjustable ribs, specialized recoil systems, and other manufacturer-specific features.

Shotgun Chamber Length

Chamber length determines the shell lengths approved for the firearm. Always follow the chamber markings and manufacturer's ammunition specifications for the exact shotgun.

2 3/4-Inch Chambers

Many field and competition over / under shotguns use 2 3/4-inch chambers, particularly when configured for clay-target and general sporting ammunition.

3-Inch Chambers

Three-inch chambers are common on modern hunting and field over / under shotguns and provide compatibility with approved shell lengths up to the firearm's chamber specification.

Barrel Length

Barrel length influences the shotgun's total length, balance, weight, sighting plane, and swing characteristics. Field and competition models may use substantially different barrel lengths.

26-Inch Barrels

Approximately 26-inch barrels are found on selected compact and field-oriented over / under shotguns, although availability varies by gauge and manufacturer.

28-Inch Barrels

Twenty-eight-inch barrels are common across many field and sporting over / under shotguns.

30-Inch Barrels

Thirty-inch barrels are frequently offered on clay-target and competition-oriented models as well as selected hunting shotguns.

32-Inch & Longer Barrels

Longer barrels are commonly associated with some trap and sporting configurations where additional forward weight and a longer sighting plane may be desired.

Barrel Regulation

Double-barrel shotguns are manufactured so their barrels produce manufacturer-specified point-of-impact relationships. Exact regulation standards differ between manufacturers and models.

Ventilated Ribs

Most modern over / under sporting shotguns use a rib along the top barrel to provide a consistent sighting plane.

High Ribs

Some competition shotguns use elevated or high-rib configurations. These designs may correspond with specialized stock dimensions and intended disciplines.

Adjustable Ribs

Premium competition models may include adjustable-rib systems. Adjustment range and procedure should follow manufacturer instructions.

Side Ribs

Some barrel sets use ventilated or solid side ribs between the upper and lower barrels. Construction varies according to shotgun design.

Shotgun Chokes

Chokes influence shotshell pattern distribution. Over / under shotguns may use fixed chokes or removable choke tubes in one or both barrels.

Interchangeable Choke Tubes

Modern field and competition over / unders frequently use interchangeable choke tubes. Choke threading and dimensions are specific to the manufacturer's system.

Fixed Chokes

Traditional and selected premium shotguns may use fixed barrel constrictions rather than removable choke tubes.

Flush Chokes

Flush choke tubes fit approximately even with the muzzle and are available in various constrictions.

Extended Chokes

Extended choke tubes project beyond the muzzle and may include visible markings, knurled surfaces, or other convenience features.

Different Chokes in Each Barrel

Because an over / under has two barrels, each barrel may use a different choke constriction when compatible with the firearm and intended application.

Steel-Shot Compatibility

Barrel and choke compatibility with steel or other non-lead shot varies. Verify the ratings for the exact firearm, choke, and ammunition before use.

Break-Action Design

Over / under shotguns use a hinged action. Opening the firearm exposes both chambers and operates the extractor or ejector system according to the shotgun's design.

Top Levers

Most modern over / unders use a receiver-mounted top lever to unlock the action. Shape, direction of movement, and internal lockwork vary by manufacturer.

Locking Systems

Break-action shotguns use locking lugs, bolts, bites, pins, or other systems to secure the barrels when the action is closed.

Extractors

Extractor systems lift shells from the chambers when the shotgun is opened so they can be removed manually.

Automatic Ejectors

Many over / under shotguns use ejectors designed to move fired shells farther from the chambers when the action opens. Exact operation varies.

Selective Ejectors

Some shotgun ejector systems distinguish between fired and unfired shells according to the firearm's mechanical design.

Single Triggers

Many modern over / under shotguns use a single trigger that fires the two barrels sequentially according to the shotgun's mechanism.

Selective Triggers

Some single-trigger designs allow the shooter to choose which barrel fires first. Control location and function vary by firearm.

Double Triggers

Certain traditional double-barrel firearms use separate triggers for each barrel, although this configuration is less common on modern over / under shotguns.

Mechanical Triggers

Some competition shotguns use mechanical trigger systems that do not rely on recoil to prepare the second firing sequence. Exact design varies by manufacturer.

Inertia Trigger Systems

Selected over / unders use inertia-assisted trigger systems. Operation should be understood from the shotgun manufacturer's owner's manual.

Trigger Pull

Trigger weight, travel, break, and reset vary among field and competition shotgun designs.

Automatic Safeties

Certain hunting shotguns automatically place the safety in a particular position when the action is opened. Exact operation varies by manufacturer.

Manual Safeties

Some over / under shotguns use a manually operated safety that remains under direct user control. Always consult the owner's manual for the exact system.

Barrel Selectors

The safety control may also function as a barrel selector on some models. Control layout and markings differ by manufacturer.

Receiver Construction

Over / under receivers may use steel, alloy, or other manufacturer-specified materials depending on gauge, price point, intended use, and firearm design.

Steel Receivers

Steel receivers are common on field and competition shotguns and may add weight compared with selected lightweight alloy designs.

Alloy Receivers

Some lightweight field guns use alloy receivers to reduce carrying weight. Structural design varies substantially among manufacturers.

Engraved Receivers

Decorative engraving ranges from simple machine-applied patterns to elaborate premium finishes. Exact decoration and finish should be verified for the listed firearm.

Case-Colored Finishes

Traditional-style receivers may use case-color-inspired or other decorative finishes depending on manufacturer and model.

Nickel & Silver-Tone Receivers

Sporting shotguns may use bright, satin, nickel-tone, silver-tone, or other receiver finishes for appearance and corrosion protection.

Wood Stocks

Walnut is widely used on over / under shotguns. Grade, grain, figure, checkering, oil finish, gloss finish, and coloration vary across manufacturers and price ranges.

Walnut Grades

Premium models may use higher-grade walnut with more pronounced figure and hand finishing, while practical field guns may use more straightforward wood selections.

Checkering

Stocks and forearms may use cut, pressed, laser, or manufacturer-specific checkering patterns.

Pistol-Grip Stocks

Pistol-grip stocks are common on hunting and sporting over / under shotguns and vary in radius, palm swell, grip thickness, and checkering.

Prince-of-Wales Grips

Selected field shotguns use more open or rounded grip shapes sometimes described as Prince-of-Wales-style configurations.

Competition Stocks

Competition shotguns may use fuller grips, wider combs, adjustable components, longer length of pull, or other discipline-specific dimensions.

Adjustable Combs

Adjustable comb systems allow changes to cheekpiece height or lateral position within the design limits of the shotgun.

Adjustable Buttplates

Some competition stocks include buttplates that permit manufacturer-defined changes in position, angle, or length.

Length of Pull

Length of pull is measured from the trigger to the rear of the stock and is a key specification when evaluating shotgun fit.

Drop at Comb & Heel

Stock drop influences the relationship between the shooter's eye and barrel rib. Manufacturer dimensions should be reviewed when fit is important.

Cast

Cast describes lateral stock offset and can influence eye alignment. Some shotguns use neutral dimensions while others offer manufacturer-specific cast.

Recoil Pads

Sporting and hunting over / unders may use rubber, ventilated, competition, or manufacturer-specific recoil pads.

Shotgun Balance

Barrel length, barrel weight, receiver material, stock dimensions, and forearm design influence how an over / under balances and moves.

Shotgun Weight

Field models may prioritize lighter weight for carrying, while competition models may intentionally use greater weight for different balance and recoil characteristics.

Lightweight Field Guns

Lightweight over / under shotguns can be convenient for upland hunting and extended field carry.

Competition Shotgun Weight

Trap and sporting models may be heavier than comparable field guns because of longer barrels, heavier receivers, adjustable stocks, and other components.

Recoil Characteristics

Perceived recoil depends on gauge, shotshell load, firearm weight, stock dimensions, recoil pad, shooting position, and individual shooter factors.

Shotgun Fit

Proper shotgun fit involves more than overall length. Length of pull, drop, cast, comb shape, grip angle, buttpad placement, and individual body dimensions can all affect how the firearm mounts.

Youth & Compact Over / Unders

Selected manufacturers offer compact models with shorter stock dimensions or smaller frames. Manufacturer-listed dimensions should be compared carefully when evaluating fit.

Women’s & Reduced-Length Sporting Models

Some manufacturers offer shotguns with altered stock geometry, shorter length of pull, or different comb dimensions intended to fit a broader range of shooters. Fit should be evaluated individually rather than solely by product labeling.

Bead Sights

A front bead is the most common sighting reference on traditional field and sporting over / under shotguns.

Mid-Beads

Some competition and sporting shotguns include a smaller mid-bead along the rib as an additional visual reference.

Fiber-Optic Sights

Selected modern over / unders use fiber-optic front sight elements, particularly on competition-oriented models.

Optics on Over / Under Shotguns

Most traditional over / unders are designed around the barrel rib rather than optical sights, although specialized hunting or manufacturer-specific configurations may offer optic mounting provisions.

Shotgun Ammunition

Use only shotshells matching the exact gauge and chamber length approved for the firearm.

Target Loads

Target loads are commonly used for trap, skeet, sporting clays, and recreational clay shooting. Shot weight, velocity, shot size, and shell length vary.

Upland Loads

Upland hunting loads are available in different shot sizes, materials, velocities, and payloads. Ammunition should be appropriate for the lawful intended use.

Waterfowl Loads

Where applicable, waterfowl hunting may require approved non-lead shot. Verify barrel and choke compatibility with the selected shot material.

Steel & Non-Lead Shot

Compatibility with steel, tungsten-based, bismuth, or other non-lead shot varies by barrel, choke, and manufacturer. Review the shotgun and choke manufacturers' specifications.

Cleaning an Over / Under Shotgun

Follow manufacturer instructions for unloading, opening the action, barrel removal where applicable, bore cleaning, chamber cleaning, hinge maintenance, locking-surface care, lubrication, inspection, and reassembly.
