Brenner SD21 Overbarrel Sound Moderator Calibre .30

The Brenner SD21 by A-Tec. A modular non-ferrous metal sound moderator with attenuation of approx. 32 dB (manufacturer's figure). Developed for maximum attenuation on the first shot or from cold barrels. The large opening also makes it suitable for large-diameter barrels.

The moderator is modular and consists of 4 modules:

- 1. Overbarrel attenuation module with stainless steel thread M15x1

- 2. Attenuation module

- 3. Attenuation module

- End cap

The highlight: one or two attenuation modules can be removed in a few seconds, making the already short SD21 even shorter. Attenuation performance will then naturally decrease. Robust and easy to dry and clean, the Brenner SD21 is the perfect complement to a hunting rifle with an M15x1 muzzle thread.

A-TEC quality, Brenner price!
