Magpul MBUS Gen 2 Flip Up Front Sight Black

The new MBUS (Magpul Back-Up Sight) GEN 2 is a low-cost, color injection molded, folding back-up sight. The Magpul MBUS Front Sight is adjustable for elevation and fits most 1913 Picatinny-railed hand guards, but is specifically tailored to the AR15/M16 platform. NEW Features for GEN 2 Reduced size for greater optics compatibility Spring-locking front sight post holds consistent elevation 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 also not compatible with MOE Hand Guards Made in U.S.A.

• Impact resistant polymer construction provides light weight and resists operational abuse
• Spring-loaded flip up sight easily activated from either side or by pressing the top
• Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.
• Clamps to most any MIL-STD-1913 Picatinny/STANAG 4694 railed hand guard and provides the same height-over-bore as standard A2 irons
• Protective wings shield the spring-locking A2 front sight post
