Blaser BD14 Over-and-Under Drilling

The Blaser BD14 gives the traditional three-barrel drilling a compact over-and-under layout. Blaser combines two rifle barrels and one shotgun barrel within a single break-action design, creating a configuration that differs from a standard rifle, shotgun or conventional drilling.

Blaser officially calls the model the Bockdrilling BD14 and also describes it in English as an over-and-under drilling. You can find additional technical details in the official Blaser BD14 manual.

At the same time, the wood stock, compact action and simple exterior lines keep the traditional appearance associated with European combination guns. The result is a three-barrel design that looks familiar while using a different mechanical arrangement underneath.

Blaser BD14 Over-and-Under Design

The Blaser BD14 arranges three barrels within a narrow barrel set. It combines a larger rifle caliber, a smaller rifle caliber and a shotgun barrel.

As a result, the BD14 brings three different barrel functions together within one break-action platform. In addition, its arrangement gives the firearm a slimmer profile than many traditional drillings that use a wider side-by-side configuration.

Blaser also uses free-floating barrels on the BD14. According to the manufacturer’s current information, the barrels can move independently as they heat and can also be adjusted in relation to each other.

Therefore, the barrel system forms an important part of the BD14 design rather than simply serving as an unusual three-barrel arrangement.

Two Rifle Barrels and One Shotgun Barrel

The barrel combination remains the defining feature of the BD14.

The design combines:

• One larger-caliber rifle barrel
• One smaller-caliber rifle barrel
• One shotgun barrel

This arrangement differs from the classic drilling setup, which commonly places two shotgun barrels alongside one rifle barrel.

Instead, the BD14 gives more emphasis to the rifle side of the combination by using two rifle barrels and one shotgun barrel.

More importantly, each barrel has its own role within the same firearm. Therefore, the three-barrel arrangement gives the BD14 a mechanical layout that stands apart from a normal double rifle or over-and-under shotgun.

The exact caliber and gauge combination can differ between individual examples. For that reason, the specifications for a particular BD14 should always match the markings on that firearm rather than relying on a general model description.

Free-Floating and Adjustable Barrels

One of the notable features of the Blaser BD14 is its free-floating barrel system.

Blaser allows the individual barrels to move and expand without forcing the complete barrel set to move as one solid unit. As a result, heat from one barrel has less influence on the others.

Blaser also allows adjustment between the barrels. The manufacturer specifically lists adjustable barrels among the features of the BD14.

In addition, Blaser states that the free-floating arrangement helps each barrel maintain a consistent point of impact even during relatively quick follow-up shots.

This system gives the BD14 a more modern mechanical approach while keeping the familiar appearance of a traditional combination gun.

Blaser BD14 Double-Lock System

The Blaser BD14 uses a double-lock system.

Blaser’s current catalog states that the system allows a second shot without requiring the shooter to recock the firearm between the two shots.

Consequently, the double-lock arrangement forms an important part of the BD14’s mechanical design.

The system works alongside the firearm’s other controls rather than adding large external parts to the action. Therefore, Blaser manages to keep the outside of the BD14 relatively simple despite the more involved three-barrel mechanism.

At the same time, the double-lock arrangement distinguishes the BD14 from simpler single-lock combination-gun systems.

Manual Cocking System

Blaser also incorporates its manual cocking system into the BD14.

The cocking slide sits at the rear of the action. In addition, opening the firearm returns the mechanism to its uncocked condition. Blaser describes this automatic decocking feature across its combination-gun range.

As a result, the cocking mechanism forms an integral part of the BD14 action rather than functioning as a separate traditional safety lever.

The system fits naturally into the break-action layout. Furthermore, Blaser keeps the main controls around the action, which helps preserve the clean appearance of the firearm.

Traditional Break-Action Layout

The BD14 follows the familiar break-action principle. Opening the action exposes the chambers and separates the barrel set from the breech.

However, Blaser adds several features of its own to the traditional arrangement. The action brings together the cocking system, trigger arrangement and controls for the three-barrel configuration.

At the same time, the exterior keeps the recognizable lines of a European break-action sporting arm.

This mix of traditional form and newer engineering gives the BD14 much of its character. It clearly belongs to the drilling family, yet the mechanical layout differs from older three-barrel designs.

Traditional Wood and Blaser Styling

The Blaser BD14 uses a traditional wood stock that suits its break-action construction.

Blaser’s current catalog lists a Bavarian cheek piece, rubber recoil pad and grade 3 wood as standard BD14 features, while other versions can use different grades and decorative finishes.

Meanwhile, the compact metal action helps prevent the center of the firearm from looking bulky despite the three-barrel arrangement.

The contrast between wood and metal gives the BD14 a straightforward European appearance. Furthermore, the relatively narrow barrel set helps distinguish it from larger drillings with wider barrel layouts.

Blaser continues to include the model within its combination gun range, alongside its other break-action combination designs.

Compact Over-and-Under Drilling Configuration

The term over-and-under drilling describes the general arrangement more naturally in English than “overhead drilling.”

Blaser itself has used the phrase “over and under drilling BD14” in its English-language catalog. The German model name, however, remains Bockdrilling BD14.

Because of this, both terms can appear naturally on the page without stuffing the description with different variations of the same keyword.

The unusual position of the smaller rifle barrel also contributes to the compact barrel set. At the same time, the arrangement allows Blaser to place three chambers into a relatively narrow break-action platform.

For that reason, the BD14 remains a distinctive example of how manufacturers can adapt the traditional drilling concept while keeping its familiar character.

Strong Vertical Locking System

The BD14 also uses a strong vertical block lock as part of its action.

Blaser specifically highlights this locking arrangement in its current catalog and connects it with the overall stability and precision of the BD14 design.

Therefore, the locking system works alongside the free-floating barrels and double-lock mechanism as one of the main mechanical features of the platform.

In addition, Blaser keeps the locking system within a relatively compact receiver. This helps the BD14 maintain its traditional proportions despite the three-barrel arrangement.

Blaser Saddle Mount Provision

Blaser designed the BD14 around the company’s original scope-mounting arrangement.

The Blaser combination gun information explains that the Saddle Mount places the mounting points directly above the chamber area while allowing the barrels to move freely.

Therefore, compatible optics can follow the compact form of the firearm without requiring a large permanent rail across the top of the action.

If a particular BD14 includes an optic, list its actual make, model and magnification separately in the specifications. That way, the description stays accurate to the individual example.

Classic Three-Barrel Character

Although the BD14 uses modern mechanical ideas, its general appearance still follows the traditional European drilling style.

The shaped wood stock, break-action receiver and compact barrel set give the firearm a familiar sporting-arm profile.

However, the three-barrel arrangement immediately separates it from an ordinary over-and-under firearm. The second rifle barrel adds another element to the design without requiring a much wider action.

Together, these details give the BD14 its recognizable character while avoiding excessive decoration.

About the Blaser BD14 Platform

Blaser developed the BD14 as a modern interpretation of the three-barrel combination gun. Rather than following the common drilling arrangement of two shotgun barrels and one rifle barrel, the BD14 combines two rifle barrels with one shotgun barrel.

As a result, the model has a noticeably different layout from many traditional drillings.

The free-floating barrel system also forms a major part of the design. In addition, Blaser allows adjustment between the barrels so that each one can work independently within the compact barrel set.

The double-lock mechanism adds another distinctive feature. Meanwhile, the manual cocking system and automatic decocking arrangement remain integrated into the action rather than relying on a conventional safety layout.

The official Blaser combination gun information provides more background on the manufacturer’s current combination-gun designs. Likewise, Gunvexa contains additional catalog information on sporting-arm models.

Finally, the Blaser BD14 combines two rifle barrels, one shotgun barrel, free-floating adjustable barrels, a double-lock mechanism and traditional wood styling. Its compact over-and-under drilling arrangement gives the model a clear identity within the Blaser combination-gun range.
