About the CZ

CZ firearms or CZ (which stands for Česká zbrojovka) is based in Uhersky Brod, a small town in the southeastern Czech Republic. CZ has its start in 1936 as a subsidiary of CZ Strakonice, which was itself a subsidiary of Zbrojovka Brno. The arms industry was growing quickly in Czechoslovakia at the time, and Uhersky Brod was chosen since it was secluded and lay beyond the range of German bombers, which, in case of an invasion, would target the arms factories first. The factory initially mostly produced pistols and small-caliber rifles; however, when German forces occupied Czechoslovakia in 1939, the company was renamed to Böhmische Waffenwerke and was forced to make machine guns, such as LK-30 and MG-17, for the German military.

After the end of World War II, the Soviets gained control of the region and the company was nationalized by the communist government, producing air weapons, machine guns, submachine guns, motorcycle and sewing machine parts. In 1957 the company started production of the Model 58, and in 1961 they introduced the world-famous Model 61 Škorpion machine pistol. The year 1975 marked the release of yet another popular model, the CZ 75 pistol which many manufacturers have since used as basis for their own products.

CZ once again became an independent company in 1992 following the fall of the Soviet Union. In the decades after, they have continued production of a variety of weapons seizing the market of law enforcement and military firearms with service pistols, assault rifles and grenade launchers with which they also helped equip the Czech army. They have strived to widen their presence on the international markets, opening a facility for assembly and repairs of CZ pistols in Peru and spreading production of their firearms (certain models of the CZ-P10 pistol) to the United States in 2019. As of 2021 they employed around 1500 workers.

CZ 511 Rifle Review

The CZ 511, a semi-automatic rimfire rifle, is a slightly improved version of the older Brno 581 which had previously been produced since the 1950s; the different name reflects the rebranding of Brno to CZ. The rifle features a cold hammer-forged threaded barrel and all-steel construction. The safety is a push-through catch at the rear of the trigger guard. The magazine release catch is located between the magazine and the trigger-guard and is activated by pushing it forward. The large capacity 8-round magazine is unusually wedge-shaped which makes it harder to adapt other magazines to CZ 511. The rifle was discontinued in 2010 when it was replaced by CZ 512.

Which rifles have interchangeable mounts

Two-piece mounts

For two-piece mounts to be interchangeable the mounting surfaces of the rifles must match in every dimension except the action length which can vary. This is because the distance between the two pieces of the mount is not fixed. If the mount has a recoil stopper, it must fit the recoil notch on the receiver. Rifles that have two-piece mounts interchangeable with CZ 511 are the following:

CZ 452 (11 mm)
CZ 453 (11 mm)
CZ 455
CZ 457
CZ 512
CZ 513

One-piece mounts

The necessary condition for rifles to have one-piece mounts interchangeable is that the mounting surfaces of these rifles match in every dimension. Rifles that have one-piece mounts interchangeable with CZ 511 are the following:

CZ 452 (11 mm)
CZ 453 (11 mm)
CZ 455
CZ 457
CZ 512
CZ 513

Our recommendations for mounts

Fixed mounts

This is the only one-piece mount available for CZ 511 and it is made by Kozap. Kozap is also from the Czech Republic, so their Slip-on mount is a great fit for CZ 511.

Detachable repeatable mounts

There are not a lot of detachable repeatable mounts available for CZ 511, but these roll-off rings from Rusan are a good choice in terms of price and quality.

Picatinny rails

This Picatinny rail is a good choice in terms of price and quality.

Help us build our riflescope mounts database

If you happen to own this or any other rifle, we would appreciate it if you could help us expand our database by sending us some photos of the rifle receiver (the bare mounting surface of the rifle without the mounts installed). For your help, our company offers a fair return in terms of practical rewards.

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.

General Features of Airgun Scope Mounts

It is common to almost all airguns that they have 11 mm dovetail on the receiver. This dovetail is full length and it is used for mounting a rifle scope or diopter. Such dovetails are basically the same as on the rimfire rifles (.22 calibre). It is important to know that they share the same mounting platform and this is why we can found airgun scope mounts also on rimfire rifles and normally, similar scopes are used on both types of rifles.

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 rigidness of the mounts is extremely important (especially with spring powered airguns). This problem is not the case with rimfire rifles, where recoil is very mild.

Mostly, these mounts are made from aluminium and can also have a screw that serves as recoil stopper. The screw can be placed vertically, but with the two part design scope mounts, screw can be placed horizontally. Although, majority of airgun scope mounts comes without recoil notches. There are two options available for mounting the scope on the airgun monoblock scope mount: 25.4 mm (1’’) or 30 mm rings. Other dimensions can also be found, however - they are extremely rare.

Normally, airgun mounts are affordable and in most cases fixed. Detachable airgun scope mounts are usually very rare. However, the most affordable airgun mounts are also the ones from the lowest quality (although, sufficient) and high quality mounts can be expensive, too.

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.

Monoblock Scope Mounts for Airguns

Monoblock scope mounts for airguns 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. However, with monoblock scope mounts, setting the proper eye relief might be an issue in some cases. 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, worth mentioning.

One Part and Two Part Design of Airgun Scope Mounts

When we are talking about two piece solutions of airgun mounts, we should not forget to mention some of the differences between one part and two part design of these mounts. One part design is easier to produce, therefore these mounts are cheaper as a rule. Versatility with one part design of scope mounts is normally poor. More options of mounting a scope are normally available with two part design scope mounts. It is good to know that airgun scope mounts for rifle scopes with rail systems are not usual (actually, they are rare). If they are available, they are normally available with two part design of scope mounts. Example for such mount could be Recknagel’s tip off mount for 11 mm dovetail on the bottom and with Zeiss rail option (ZM/VM) on the top. They also offer a LM rail version of these mounts.
