Upgrade Your Weapon’s Attachments With Castellan Rails

We have a great selection of Castellan airsoft switch rails and rail panels to upgrade your weapon with ease. 

Being able to quickly and easily switch between gun attachments and accessories can give you a real advantage during gameplay, so make sure you have the best on the battlefield with Castellan. With different lengths, colours, and style options available, you can find the perfect fit for your weapon.

The Best Castellan Switch Rails & Rail Panels

Made using high-quality polymer, these Castellan switch rails allow you to attach accessories like flashlights, lasers and grips to your airsoft gun with a handy M-Lok attachment point, while our rail panels provide a comfortable grip for improved handling and control. 

We stock the M-Lok Switch Rail in 2 different lengths – 13” and 12”. Both are compatible with AEGs. This switch rail is lightweight, so it won’t add too much bulk to your weapon, and you’ll still have great manoeuvrability. 

Our Castellan 5 Slot URX Rail Panel fits standard Keymod rail systems for the fitting of a 20mm Picatinny. We also stock the 9 Slot M-Lok Rail Panel, which is compatible with M-Lok rail systems, also for fitting a 20mm Picatinny rail. Both of these are also very lightweight and make it super convenient to customise your weapon’s attachments.
