The DoubleStar Flip Up Front Sight was designed to use with a picatinny rail gas block. It utilizes an A2 front sight post for ease of adjustment. The sight features a protective bar across the top of the sight to prevent dirt and grime from building up in the sight as well as protecting the post from damage. Made of aircraft aluminum and hardcoat anodized black, this front sight was designed for heavy use.
Note: This sight will NOT work on a same plane system! For use with a picatinny rail gas block!!
