Description

Two Profiles. Same Performance.

RSV1 – Wavy Profile
A flowing, organic exterior with subtle contouring. RSV1 offers a softer visual language while retaining the same internal geometry and suppression performance as RSV2.

RSV2 – Chamfered Profile
A sharper, faceted design with clean chamfers and a more technical aesthetic. RSV2 is visually bold but mechanically identical inside.

Profile choice is purely aesthetic — performance remains unchanged.

Single Chamber.

The Single Chamber is an additional expansion module designed to extend and customise your existing Reservoir Mod system.

Why choose Reservoir Mods?

Because effective sound suppression isn’t about brute size — it’s about controlling air intelligently. Reservoir Mods are tuned to manage pressure smoothly, reducing sharp crack without over-damping the system or upsetting the rifle.

Quiet. Controlled. Deliberate.
