The Behemoth is a next gen moderator, modular and with extreme sound suppression qualities. A lot is due to its Valenki like inner felt, which muffles sound and reduces pitch. As lots of air is coming through when you’re shooting, it is only normal that after many, many shots, it might wear down a bit. That’s when this repair kit comes in handy. Enough to replace the felt in 10 modules, it will guarantee continuous suppression throughout a big part of your Behemoth’s shooting life.
