MM S400 Twin Island Rail Sight Set

The MM S400 Twin Island Rail Sight Set is our in-house 3D printed take on iron sights for the S400, built around a pair of low-profile island rail sections rather than a single bulky sight housing. It's an aesthetics-focused piece for players who find the stock sight picture too plain or want a more distinctive front-and-rear silhouette on their blaster.

The twin-island layout keeps things minimalistic, giving the S400 a sleeker top profile compared to bulkier sight options without cluttering the rail. It mounts directly onto the S400's rail system as a set — front and rear sight together — rather than as separate purchases. Available in Black, Orange, and White so you can match it to your existing S400 colourway or run it as a contrast piece.
