Magpul MBUS Front Sight ( Gen 2 )
You already know about these Poly Sights. Everyone has 'em, and for good reason. Follow the herd on this one, don't be a hipster renegade and go elsewhere, these are rad.
The MBUS (Magpul® Back-Up Sight) is a low-cost, color injection molded, folding back-up sight. The MBUS Front Sight is adjustable for elevation and fits most 1913 Picatinny-railed hand guards, but is specifically tailored to the AR15/M16 platform.
Made in U.S.A.
