RESERVOIR MODS
The Reservoir Mod is a compact, modular airgun moderator engineered to do one thing exceptionally well: reduce muzzle noise without compromising accuracy.
Designed and built In England by 3 Legged Thing, Reservoir Mods use a carefully tuned multi-chamber system to manage airflow, strip excess pressure, and quiet the shot at the source. The result is a cleaner report, tighter follow-through, and a more controlled shooting experience.
Available in two profile styles and two lengths, every Reservoir Mod delivers the same internal performance — the choice is simply how it looks and how much volume you want.
Two Profiles. Same Performance.
Wavy Profile (3LTRSV1)
A flowing, organic exterior with subtle contouring. RSV1 offers a softer visual language while retaining the same internal geometry and suppression performance as RSV2.
Chamfered Profile (3LTRSV2)
A sharper, faceted design with clean chamfers and a more technical aesthetic. RSV2 is visually bold but mechanically identical inside.
Profile choice is purely about looks and feel — performance remains unchanged.
Two Sizes
Compact design for balance and handling:
5 chamber modular design
XL design for precision and ultimate quiet:
8 chamber modular design
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.
