KFM Taper Lock Flash Hider
 
The RD KFM taper lock flash hider is their in-house designed suppressor mount. Originally designed around an agency requirement to reduce visible flash signature by 90% over a standard A2 Birdcage, with the flash hiding geometries not exceeding the form factor of the A2 Birdcage, while also acting as a suppressor host. 
 
Adaptable all the way from 5.56mm carbines to 12.7mm machine guns, with various thread pitches available, the KFM is the standardized mount to install RD suppressors for whatever the mission set.
