MBUS® - Magpul® Back-Up Sight – Front GEN 2

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 1913 Picatinny-railed hand guards, but is specifically tailored to the AR15/M16 platform.

Made in U.S.A.

Features

• 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
