The Ultradyne C4 Muzzle Device Combo includes both Mercury Muzzle Brake and Dynamount Flip-Up Front Sight. The Ultradyne Mercury has been meticulously engineered to provide superior recoil reduction and neutralize muzzle rise with a smooth, balanced release of blast energy. Progressive 90° side ports vent combusting gases at intervals that spread out the recoil impulse for efficient, accurate follow-up shots. The Mercury Compensator is light-weight and includes wire-cutter design on the front.

The C4 Ultradyne Flip-Up Front Sight features a purely concentric sight picture with windage and tool-less elevation adjustability. Designed for maximum flexibility, the Dynamount Front Sight is barrel mounted which greatly reduces sight movement compared to free-float handguard mounting. The Flip-Up Front Sight is also indexable to 45 Degrees for offset use, making it an absolute must have feature for competition shooters engaged in 3-Gun shooting.
