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.
An elevation adjustment tool is included, but most aftermarket A2 front sight adjustment tools may be used as well.
FEATURES
Spring-loaded flip up sight
Easily activated from either side or by pressing the top
Protective wings shield the spring-locking A2 front sight post
Impact resistant polymer construction provides light weight and resists operational abuse
Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc.
Compatible with most MIL-STD-1913 Picatinny / STANAG 4694-railed hand guards* and provides the same height-over-bore as standard A2 irons
Made in the USA.
