Originally designed for the US military’s SOPMOD rifle enhancement program, the KAC M4 Folding Front Sight is a low-profile backup sighting solution that is designed to be attached to the top rail of a rifle’s handguard. When stowed in the folded position, the M4’s sight base extends back to envelope the front sight leaf on the right and left side, helping to protect it from damage.

    Where this review shines is the vendor. Rooftop is what you might call “the shit.” Prompt shipping and products in stock with a LIVE counter. Paving the way for me making more purchases, KAC and Rooftop are a match made in heaven. The front sight great too…

  2. Curtis Simmons (verified owner)

    As expected, sight is high quality and looks great on the gun. Shipping was quick. Couldn’t ask for more!

    Got this for my surplus CQBR kit. Rooftop is a boutique shop for gun nerds like myself and I appreciate their hard work and dedication. The sight, like the site, is top notch all around.
