Specna Arms Set of 5 RIS Rails for KeyMod


The Specna Arms Set of 5 RIS Rails for KeyMod is a practical set of five aluminium mounting rails that allow you to fit a KeyMod handguard with additional RIS mounting points. This enables you to easily combine accessories compatible with a standard RIS/Picatinny rail with a KeyMod platform.
The set includes rails in five different lengths, so you can decide how much mounting space you need for each position. This prevents you from mounting unnecessarily long rails on your handguard and gives you more freedom to put together a practical and well-organised configuration.
From KeyMod to RIS mounting points
KeyMod handguards are designed to attach accessories either directly or via separate mounting rails. With this Specna Arms rail set, you can add RIS mounting points to a compatible KeyMod handguard in the desired locations.
This is particularly useful when you’re using accessories that don’t have a KeyMod mount but are suitable for mounting on a RIS/Picatinny rail.
You only fit a rail where you actually need it. This means the rest of the handguard remains free of unnecessary parts.
Five different rail lengths
The set consists of five rails of different lengths. This means you can use a suitable rail for both compact and larger accessories.
The lengths supplied are:
- 13,5 cm
- 9,5 cm
- 7,5 cm
- 5,5 cm
- 4,5 cm
A short rail can, for example, be used when only a limited mounting surface is required, whilst the longer rails offer more space for larger accessories or different positioning.
Durable aluminium construction
The five rails are made from aluminium. This material offers a good balance between strength and relatively low weight and is therefore widely used in components for airsoft replicas.
The complete set has a stated weight of 160 grams.
Thanks to their black finish, the rails also complement black KeyMod handguards and other tactical components.
Includes assembly key
Specna Arms includes a mounting key with the rail set. This means you’ll have the tool supplied for fitting the rails straight away.
The various rail sections can be fitted to suitable positions on a compatible KeyMod handguard. This allows you to decide for yourself where extra mounting space is required.
Practical insights
The main advantage of this set lies in the various lengths available. Instead of fitting the same length of rail everywhere, you can choose the length that best suits the accessory and the desired position.
This is of interest to airsoft players who want to keep their KeyMod handguard as simple as possible. You only add RIS rails where they’re actually needed.
With five separate rails, you also have plenty of options for creating multiple mounting positions on the same handguard or saving the remaining rails for another compatible replica.
Who is the Specna Arms Set of 5 RIS Rails for KeyMod suitable for?
The Specna Arms Set of 5 RIS Rails for KeyMod is suitable for airsoft players who use a KeyMod handguard and wish to be able to attach accessories with a compatible RIS/Picatinny mount to it.
The set is particularly useful if you want to use different accessories and therefore need a variety of rail lengths and mounting positions.
Before purchasing, always check whether your handguard actually uses the KeyMod mounting system.

Common mistakes
- Before purchasing, please check that your handguard actually has KeyMod slots. This rail set is specifically designed for the KeyMod mounting system.
- Do not confuse KeyMod with M-LOK. Although both systems are used to attach accessories to handguards, the mounting systems are different.
- Do not automatically fit the longest rail if a shorter version is sufficient. A suitable rail length keeps the configuration neat and tidy.
- After installation, always check that the rail is correctly and securely fixed in place before fitting any accessories.
- Please bear in mind the available space around other parts and accessories on the handguard.
