Airgun monoblock scope 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

Pivot mounts are a special kind of repeatable mounts that are especially popular in Europe and mainly produced by European manufacturers. Most notable among them are German Companies like EAW (Ernst Apel Wurzburg), Recknagel, Henneberger and MAK. These Companies were also among the first to produce mounts of this type. Non German companies like Rusan are also following this trend.

Main benefits of pivot mounts, or swing mounts as they are sometimes called are:

  • 100% repeatability,
  • very quick and easy detaching and reattaching,
  • extremely durable; most mounts of this kind are tested on 10000 or more reattachments,
  • size and weight; light and small, elegant.

There are also some minor weaknesses that such mounts posses and they are: they are usually more expensive than other types of mounts, the installation on the rifle should be done by a skilled gunsmith and most of these mounts are higher than 14 mm.

A distinct feature of pivot/swing mounts is the way the scope attaches to the rifle. The front foot of the mount on the scope is inserted in the front base under a 90 degrees angle to the barrel. Then the entire scope is pivoted around the front base until it is locked into position by the rear base.

Pivot mounts of all types enable windage correction on the rear base at the time of the mounts installation. There are three main types of pivot mounts which are distinguished by the type of the rear base:

  • EAW style rear base: produced by EAW and Rusan,
  • Dovetail rail base: produced by Recknagel, Henneberger, MAK and others.
  • Leupold type rear base
