Specna Arms 25mm Two-Piece Optics Mount for RIS Rail (low)

Would you like to mount a riflescope with a 25 mm tube securely and relatively low on your airsoft replica? The Specna Arms 25 mm Two-Piece Optics Mount for RIS Rail (Low) is an all-metal mounting kit consisting of two separate mounting rings. The rings have a diameter of 25 mm and are designed for attachment to a standard 22 mm RIS rail.

This ‘Low’ version is designed to position the optic lower above the replica. The two-piece construction gives you the freedom to adjust the position of both rings to suit your riflescope. Fabric inserts are fitted on the inside to help prevent the housing of your optic from being scratched during fitting.

Why choose the Specna Arms 25mm Two-Piece Optics Mount?

A good optical device deserves a suitable and sturdy mount. This Specna Arms set comprises two separate metal rings for rifle scopes and other suitable optical devices with a 25 mm tube diameter.

Thanks to the two-piece design, you can decide for yourself how much space there is between the two rings. This allows you to take into account the construction of your scope, the position of the adjustment turrets and the available rail space on your replica.

The combination of an all-metal construction, 22 mm RIS compatibility and protective fabric inserts makes this set a practical mounting solution for various airsoft builds.

Suitable for optics with a 25 mm tube

The mounting rings have an internal diameter of 25 mm.

This means that the mount is designed for suitable optics with a tube diameter of 25 mm.

Always check this measurement before purchasing a scope mount. This is because the tube diameter is not the same as the diameter of the objective lens.

A scope marketed, for example, as a 3-9x40 has a 40 mm objective lens, but that does not mean that the central tube is also 40 mm thick.

For this mounting kit, the relevant tube of your optic must therefore be approximately 25 mm.

Two-part construction

The Specna Arms mount consists of two separate mounting rings.

This means you are not restricted to a fixed distance between the two mounting points. You can position the rings on the rail in places that best suit the available space on your optical device.

This is particularly useful for riflescopes where the adjustment turrets or other controls are situated between the mounting points.

By positioning the rings correctly, you can prevent the mount from obstructing key parts of the scope.

Low version for a lower optical position

Specna Arms refers to this variant as the Low version.

This means that it is designed to position a suitable optical component relatively low above the rail.

A lower optical position can be comfortable if the design of your replica allows for a natural cheek weld and you do not need any extra space for a large objective lens.

Ultimately, the height that works best depends on your replica, the sight used and your personal viewing position.

The manufacturer does not specify an exact installation height in millimetres for this ‘Low’ version. We have therefore deliberately chosen not to state a specific height.

For standard 22 mm RIS rails

The mounting rings are suitable for fitting to a standard 22 mm RIS rail.

This means they can be used on many modern airsoft replicas that are fitted with such a rail.

Examples include:
　• Airsoft sniper rifles
　• DMR builds
　• Assault rifles with a riflescope
　• Outdoor replicas with a 25 mm optic

Before purchasing, check both the rail on your replica and the tube diameter of your optic. Both must be compatible with this mounting kit.

All-metal construction

The entire mount is made of metal.

A sturdy construction is important for a scope mount, as the optic should move as little as possible relative to the replica whilst in use.

If a mounting ring comes loose or shifts, your set zero may also change.

You should therefore check after fitting that both rings are securely fastened and, during routine maintenance, check from time to time that the fixing screws are still firmly in place.

Fixing with Allen screws

The mounting rings are secured around the tube of the optical unit using Allen screws.

A suitable Allen key is supplied as standard.

When assembling, it is advisable to tighten the screws gradually and evenly. This ensures that the pressure is distributed as evenly as possible around the optic tube.

The scope must remain firmly in place, but there is no need to tighten it excessively, as this may actually cause unwanted stress on the optic.

Fabric inserts protect the lens

Fabric inserts have been fitted to the inside of both rings.

These ensure that the metal mounting rings do not come into direct contact with the finish of the optic.

This reduces the risk of scratches during assembly and use.

That’s a small but practical detail, especially if you regularly fit or remove a rifle scope, or if you want to keep your rifle scope in good condition.

Compact low-profile mount for airsoft

As this is the ‘Low’ version, the mount is particularly suitable for setups where you do not want to position the optic unnecessarily high above the replica.

A lower mounting position can create a compact look and a low eye-level.

Whether that’s actually more comfortable for your setup depends, amongst other things, on the shape of the stock and the face protection you use when playing.

For example, if you’re using a relatively large mesh mask, a higher optical position can sometimes be more comfortable. If you’re using compact goggles and can easily achieve a good cheek weld, a low-mount can actually work very well.

Weight of approximately 105 grams

The complete two-piece assembly set has a stated weight of approximately 105 grams.

This means that the extra weight remains relatively limited, although you do, of course, need to factor in the weight of the riflescope itself.

Particularly with longer sniper and DMR builds, the total weight of the scope and mount can become noticeable.

By taking both weight and position into account from the outset, you can prevent your replica from feeling unnecessarily top-heavy.

Black finish

De Specna Arms 25mm Two-Piece Optics Mount is uitgevoerd in Black.

This means the mount can be easily combined with black riflescopes and most modern airsoft replicas.

This gives a neutral and functional look, particularly on sniper, DMR and outdoor builds.

Practical tip

When choosing scope rings, always check the tube diameter of your optic, not just the size of the objective lens. This mount is designed for a 25 mm tube. Also check that the ‘Low’ version leaves sufficient space between the objective lens and your replica. Fit both rings straight and tighten the screws gradually and evenly.

Advice from Airsoft-Legends

The Specna Arms 25mm Two-Piece Optics Mount for RIS Rail (Low) is a practical choice if you want to mount a riflescope with a 25 mm tube relatively low and securely on your airsoft replica.

The two-part design gives you the freedom to adjust the position of both rings to suit the construction of your scope. This allows you to take into account adjustment turrets and other components that you do not want to obstruct with a mounting ring.

The Low version is particularly useful if you want to maintain a low line of sight and have sufficient space between the objective lens and your replica. If you are using a large objective lens or a lot of face protection, check beforehand whether a Low mount is actually the right choice for your setup.

We also find the fabric inserts on the inside to be a useful feature. They help prevent the metal rings from causing unnecessary scratches to the body of your riflescope during fitting.

So, before you buy, be sure to check the two most important measurements: a 25 mm tube diameter on the optic and a compatible 22 mm RIS rail on your replica.

If that combination is right for you and you want to mount the riflescope as low as possible, then this metal Specna Arms two-piece low-mount is a neat solution for your sniper, DMR or rifle build.
