Magpul | MBUS 3 Front Sight | Black

Magpul's MBUS 3 front sight adjusts for windage and elevation without tools -- a real advantage when you're zeroing at the range instead of hunting for an Allen wrench. It shares the same low-profile folding design as the rear sight (0.44 inches folded, an ambidextrous push-button to deploy) and locks up at true co-witness height, so it's there instantly the moment your optic goes down.
