Magpul MBUS Back Up Folding Sight - FRONT - Black



The MBUS (Magpul BackUp Sight) is a low-cost, color injection molded, folding backup 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.
  • Elevation adjustment tool included, but most aftermarket A2 front sight adjustment tools may be used as well.

SPECIFICATIONS:
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.

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.
