I have a few of these Chevron Front Sight Posts from Blitzkrieg Components and love them. They are an awesome upgrade to any front sight that accepts a mil spec style threaded post. Instead of just a simple black post you have this super high contrast Chevron with a very fine point at the top. They offer these in an All Black, Black with White Stripe, Black with Luminescent Stripe and Black with Luminescent/Tritium Dot models. For the month of February, save $5 off all Chevron front sight posts and get Free Shipping.
