The History of Sako

Sako (Suojeluskuntain Ase- ja Konepaja Oy) is rifle and ammunition manufacturer located in Riihimäki, Finland. It was founded in 1921, after the rifle repair workshop, opened in former Helsinki brewery, became independent of the civil guard. The workshop grew into a weapons factory, which produced hunting rifles as well as cartridges and moved its headquarters from Helsinki to Riihimäki. The first civilian rifle bearing the name Sako, was the L42, prototyped in 1942 and commercially manufactured a few years later.

After the World War II, domestic hunting culture thrived and Sako invested in development of hunting rifles. Due to this investment, domestic sales increased along with export to the USA and the rest of the world. In the 1980s, Sako merged with another firearm manufacturer, Tikkakoski and gained a valuable rifle line called Tikka. The production of military and law enforcement weapons started when Finnish defence forces ordered assault rifles and cartridges from Sako.

The company has changed multiple owners since 1921, but has ultimately been sold to Italian Beretta Holding in 2000. In 2006, Sako celebrated its 85th anniversary by launching a new hunting rifle family, Sako 85. In 2020, Sako introduced S20, the first truly hybrid rifle, designed for both; hunters and tactical shooters. Another novelty presented by Sako in 2020 was a brand new, lead-free Sako Powerhead bullet.

Sako A7 S Rifle Review 

Sako A7 is the result of Sako's aspiration to create a rifle that sits in the price range between premium Sako 85 and more affordable Tikka T3. It was introduced back in 2008. The A7 uses a detachable box magazine that holds a single-stack column of cartridges. The rifle comes in two action lengths; S and M and this naming is source of confusion, because S represents Short action (SA) and M represents Long action (LA). One of the advantages of different receiver lengths is improved rigidity of the receiver. The top of the action has 4 drilled holes for mounting purpose, rather than tapered dovetail, which Sako usually uses.

The same mounting surface can be found on Browning A-Bolt & Eurobolt; the only dimension that doesn’t match is the long distance between the holes (B dimension), which means two piece mounts from those two rifles will fit Sako A7 and vice-versa. One piece mounts, however aren’t interchangeable, because the B dimensions don’t match.

Scope Mounts Interchangeable With Sako A7 S

Rifles That Have One-Piece Scope Mounts Interchangeable With Sako A7 S

The necessary condition for rifles to have one-piece scope mounts interchangeable is that the mounting surfaces of these rifles match in every dimension.

Unfortunately, we currently lack information regarding interchangeable mounts for the Sako A7 S. 

Should you have any additional information regarding possible mount matches, please contact us. We would gladly accept your help and expand our database accordingly.

Best Scope Mounts for Sako A7 S

Fixed Scope Mounts for Sako A7 S

If you want to have fixed mounts, we recommend you to install Picatinny rails and then ring mounts on top of them.

It is ideal to place a Picatinny rail of the same material on the rifle receiver, because of the mechanical reasons.

More about that in our article:

The other option for fixed mounts are the ones, where rings are installed directly on the receiver.

We would like to emphasize that we don’t recommend installation of two-piece mounts unless installed by a gunsmith. The reason for that is that the two-piece mounts can be installed sideways, therefore the force will be exerted on the housing of the scope and bend it when the screws will be tightened, which will lead to shot inaccuracy. The scope will stay bent even after the screws are untightened and this will lead to voided warranty.

Detachable Repeatable Scope Mounts for Sako A7 S

For detachable repeatable mounts we would recommend EAW pivot mount.

The only Dentler rails available for Sako A7 rifles are Dentler BASIS, which allow only Dentler mounts to be installed on them. It is one of the most reliable and accurate quick release mounts for Sako A7 on the market. Unfortunately, Dentler BASIS bases don't support adjustments on the bases, meaning they are not as revolutionary as the Dentler BASIS VARIO.

An explanation of Dentler mounts can be seen in our Roundtable video:

*We would like to stress that some mounts can be found that have the wrong dimensions between the holes for mounting and therefore will not fit Sako A7 rifles. A7 only accept mounts, which have the distance between the holes 84,8 mm (S) or 95,6 mm (M).

Help Us Build Our Riflescope Mounts Database

If you have this rifle or any other rifle at home, we would really appreciate it if you could send us some photos of the rifle receiver (mounting surface of the rifle when there are no mounts installed), because it would help us expand our rifle mounts database. If you send us a photo of rifle receiver which we don’t already have, that would be of great value to us and we will definitely reward you for your help.

Please send us an email for more information. You can contact us here: info@optics-trade.eu

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.
