MAGPUL MBUS SIGHT – FRONT

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:

• Easily activated from either side or by pressing the top
• Protective wings shield the spring-locking A2 front sight post
• 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.
• MBUS – Front
• Weight, w/ hardware: 1.2 oz.
• Height above rail, stowed: ~0.51 in.
• Length, stowed: 2.6 in.
• Length, deployed: 1.5 in.

 ELEVATION ADJUSTMENT:

• ~1.6 MOA (1.886"/100m) per click with a 14.5" sight radius
• ~1.2 MOA (1.367"/100m) per click with a 20" sight radius

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.
