Airgun monoblock scope mounts

Pivot Mounts

Introduction

Airguns or pellet guns (the name comes from projectiles they shoot – pellets) are popular among all generations of people with a variety of different interests.

They are used for plinking, hunting, sport competitions etc. All these activities demand variety of different airguns. A lot of these applications do not require a rifle scope for using an air gun, but some of them do – especially hunting or long range shooting.

It is common to almost all airguns that they have 11 mm dovetail on the receiver. This dovetail is then used for mounting a rifle scope or diopter.

There are two types of airguns available on the market:

  • spring-powered airguns and

  • PCP airguns.

Spring-powered airguns require manually compressing high volume of air with spring and piston, which can be achieved by breaking the gun (or using another type of lever) and compressing the spring.

On the other hand, PCP stands for pre-charged pneumatic guns that use pre-filled reservoir from an external air source (like compressor or diving cylinder). In both cases, compressed air powers the pellet.

When thinking of mounting a rifle scope on the airgun, we have to consider that spring powered airguns have strong recoil in both directions. This is why the robustness and ridigness of the mounts is extremely important (especially with spring powered airguns).

Mostly these mounts are made from aluminum and usually have a screw that serves as recoil stopper.

There are two options available for mounting the scope on the airgun monoblock scope mount:

Adjustable inclination on the rifle scope mounts is advisable, usable and a lot of times needed (because of the imperfections of different parts – rifle, mount, rings and dovetail). Some of the mounts also have recoil buffer available. There are also available shock absorbing recoil buffers that can be bought separately and installed behind the scope mount and help to absorb recoil.

PROS

Monoblock scope mounts are definitely more reliable than two-piece scope mounts. This is normally because they can handle recoil much better. They are robust, rigid, hard and they offer great clamping surface for the dovetail.

CONS

It depends on how much a look is important to you (compared to functionality), but monoblock scope mounts in most cases look bulky and they are also heavier because of more material used.

More quantity is somehow logical; there are no gaps between front and rear scope ring. To be even more accurate – between front and rear base.

We should also not forget that in some cases it can be really difficult to set the proper eye relief. Also, monoblock mounts are almost always more expensive than similar two piece mounts.

Clamping surface on the rail which is connected to the rings in one piece is usually higher than it can be with comparable two piece mounts. This might also be an disadvantage we should mention.

Conclusion

In our opinion, airgun monoblock scope mounts are much better solution for airguns, compared to two piece mounts.

Main reason for this is that they handle the recoil of springs much better.

This is in the first place connected to durability, duration of using such mount, rigidness, robustness and toughness.

It is true that monoblock or one piece scope mounts are more expensive than others, however, they are worth the price difference

There are two terms found for similar thing: quick release scope mounts and quick detach scope mounts. Term quick release scope mounts is used mostly in Europe and quick detach scope mounts is used mainly in USA, although they mean the same thing. With these terms we describe a scope mount that can be quickly removed from the rifle in the field without using any tools and quickly attached back on the rifle when needed.

Main advantages:

  • possibility to use multiple scopes on the rifle,
  • easy transportation of the scope and the rifle separately,
  • if scope fails, it is possible to immediately detach it and use iron sights.

FIXED vs DETACHABLE scope mounts

Fixed scope mounts are mounted to the rifle with screws and sometimes even with glue. This means that it is impossible to attach or detach the scope mount using bare hands without using tools. It also means that they are not meant for constantly being attached on or detached off the rifle. Once you screw the mount on the rifle, it normally stays there for a longer period of use.

Detachable scope mounts offer possibility to attach or detach them without using any tools. This is extremely handy while transporting the rifle and the scope separately and it also offers multiple solutions of different optics on the same rifle. Detachable scope mounts can be attached or detached from the rifle in a matter of seconds, using bare hands.

DETACHABLE vs REPEATABLE scope mounts

It is important to know and understand expressions “detachable” and “repeatable” while talking about scope mounts. Term detachable scope mounts implies scope mounts that can be quickly attached or detached without using any tools. However, when you detach this kind of mount and attach it back on the rifle, it is recommended to zero the rifle before using it again. Procedure of detaching and again attaching the mount will probably need a sighting in before next shooting, because mount will not be secured on the rifle in the perfectly same position and conditions as it was before detaching it off the rifle.

On the contrary, repeatable scope mounts are most sophisticated mounts. These scope mounts are also detachable, however – they provide removing scope from the rifle and attaching it back again without zeroing the rifle every time. This means that they are made more precisely and that they are offering a possibility of using different optical sights / scope on the same rifle. These mounts are ideal for hunters who can use optical and iron sights interchangeably, depending on the needs in different situations. With the repeatable scope mounts, it is useful to keep them oiled as well as the upper part of the rifle, so that repeatability is more ensured. With a touch of oil, the repeatability might be better, because parts of the mount will always return to their previous locations.

Different types of repeatable scope mounts:

  • Pivot mounts,
  • Dentler mounts,
  • Picatinny repeatable mounts,
  • 12 mm dovetail repeatable mounts (for break barrel rifles, such as Steyr Duett, Blaser B750, Fair Combi, Fair SLX 800, Bettinsoli rifles, etc.),
  • Original repeatable mounts, made by manufacturers of rifles for their rifles (Blaser mount, Sauer SUM mount, Mauser M03 mount, Steyr Monoblock mount, etc.).

TIP OFF / ROLL OFF vs SLIDE ON mounts

Nowadays, there are a whole lot of different possibilities, made for attaching riflescopes on the rifles. There are also a lot of different expressions, having the same meaning. It is good to know that tip off and roll off mounts are basically the same thing. They represent quick release scope mounts for dovetails and rails which can be rolled or tipped off the rail vertically to the side of the rail. On the contrary, there are also slide on mounts available on the market. They represent quick release scope mounts that can be slided on or off the rail or dovetail from front or rear side of the rail / dovetail. All of these expressions are mainly used for separate rings that can be attached to the rails / dovetails. As far as functioning the rifle, it does not matter which one of these mounts you choose – tip / roll off or slide on mounts. If they are installed correctly, they are all going to work. However, the main difference between them is the principle of attaching them on rails on dovetails.
