The Apollo Max 3-Piece Combo features the innovative C4 Dynamount Front Sight, the C4 Rear Sight along with the high-performance Apollo Max Compensator. It all starts with the Dynamount System which ensures superior accuracy by mounting to the barrel instead of a free floating handgaurd along with extending the firearms sight radius. The C4 Rear Sight boasts a ballistically calibrated elevation system that adjusts in 50-yard increments from 200 to 600 yards. In tandem the C4 Sight System offers a dual aperture sighting system that is changing the way shooters think about iron sights. Compared to most BUIS systems that utilize a sight picture that is non-intuitive and requires the brains visual systems to align a circular rear aperture with a rectangular front post shape while simultaneously ignoring the ears that protect the front sight post. In contrast, the C4 Sight System creates a perfectly concentric circle-within-circle sight picture that is drastically more intuitive than traditional iron sights, allows the shooter to see the target not cover it, enables faster sight acquisition, reduces the effect of parallax and gives the ability to consistently shoot accurately out to 600 yards and beyond. Paired with the Apollo Max which sets the standard for performance by providing breakthrough recoil reduction and unparalleled muzzle compensation for those who refuse to settle for second best.![]()
