Primary Weapon Systems FSC30

This brake/compenstator was a blast to shoot literally. It reduced muzzle flip approximately 70% in my opinion. The concussion was huge. Overall this device works as advertised but I would not want to fire it indoors.

I have fired my 16" FAL Carbine a few time in an enclosed shooting point. It has a Vandenburg custom brake on it, very effective, but the concussion make it a open spaces choice.
