Product Info for Ultradyne C4 5.56 Dynamount Folding Front Sight +Ap UD10290

The Ultradyne C4 Dynamount Front Sight / Apollo S Compensator Combo features the innovative C4 Dynamount Front Sight which ensures superior accuracy by mounting to the barrel instead of a free floating handgaurd along with extending the firearms sight radius. Additionally, the purely concentric circle-within-circle sight picture of the C4 Sight System 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 at targets that are close or at extreme distances. Increased flexibility by having windage and elevation along with the ability to index at 45 or 90 degrees make this sight the best on the market. Paired with the Apollo S which provides a balance between extreme recoil reduction and less aggressive venting of gas without sacrificing the elimination of muzzle rise.
