The new MBUS (Magpul Back-Up Sight) GEN 2 is a low-cost, color injection molded, folding back-up sight. The MBUS Front Sight is adjustable for elevation and fits most Picatinny-railed hand guard equipped weapons, but is specifically tailored to the AR15/M16/M4 platform.
NOTE: Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed fore end on the same plane as the receiver rail. Because of this the sight is not compatible with the MOE Hand Guard.
Made in U.S.A.
Impact resistant polymer construction provides light weight and resists operational abuse
