The Ultradyne C4 Sight System Combo includes the Dynamount Flip-Up Front Sight, Flip-Up Rear Sight and Mercury Muzzle Brake. The Ultradyne C4 Flip-Up Rear Sight utilizes Ultradyne's exclusive dynalign sight picture technology for accurate and immediate acquisition. Most BUIS systems utilize a sight picture that is non-intuitive. In such systems, the brain's visual systems are asked to align a circular rear aperture with a rectangular front post shape while simultaneously ignoring the 'ears' that protect the front sight post. Dynalign's circle-within-circle sight picture allows for faster sight picture acquisition. Additionally, the use of a front aperture further reduces parallax effect which makes accuracy less depend on precise sight alignment. Dynalign is a faster and more accurate sight picture than can improve shooting performance. 

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.

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.
