The Wolfman is already one of the best subgun silencers you can own. It's adaptable, modular, and dead quiet. The best and strongest way to mount it is with Dead Air's KeyMicro adapter. With it, there's no longer a need for the outdated technology of a 3-lug mount. You get a more robust quick attach method without the inherent issues of a 3-lug. While the Wolfman is optimized for pistol-caliber carbine platforms, the KeyMicro adapter makes the Wolfman a great light-weight solution for your 5.56 carbine. The KeyMicro Kit offers over $200 in savings by coming with the 1/2x28 Keymicro Brake and KeyMicro adapter.
