Entropique Design

Entropique Design is a small workshop in Brive-la-Gaillarde, in central France, that designs its own sound reducers and barrel parts for airsoft replicas. The core product is the RDS ZE-C, a carbon-bodied muzzle device offered in a slim 42 mm diameter and a wider 55 mm diameter, each in several lengths so it can be matched to short or long builds. Inside, the reducer uses a buffer and spring system with melamine foam and fart flaps, and every wear part can be bought on its own: replacement heads and buffer tops, spring sets in five wire thicknesses, foam sets, short screws and adapters that let a tracer unit sit at the front. Alongside the reducers the shop makes carbon outer barrels in set lengths or cut to the length the player asks for, plus a buffer for MCX-style replicas. The home page shares a sound test on an HPA replica, comparing the noise spectrum with and without the ZE-C fitted. Orders are handled through its own online store.

No shop on Mexar lists them yet.
