Magpul MBUS MSR Back-up Sight

Low-cost, folding back-up sights specifically tailored for the AR15/M16/M4 platform, the Magpul® MBUS® MSR Back-up Sights activate and adjust easily to give you trustworthy accuracy in a pinch. These sights clamp to nearly any MIL-STD-1913 Picatinny/STANAG 4694 railed hand guard on the same plane and provide the same height-over-bore as standard A2 irons. Made of impact resistant polymer, these lightweight sights can stand up to operational abuse. Both front and rear sights are spring loaded to flip up when activated on either side of the sight or by pressing the top. Both front and rear sights feature protective wings to shield the sights, which also fold out of the way under impact. Rear sight features a dual aperture and windage adjustment with the detent knob. Front sight features elevation adjustment and spring-locked post that holds consistent elevation. Generation 2 sights. Front and rear sights sold separately. Made in USA.

• Spring loaded to flip up when activated on either side of the sight or by pressing the top
• Provide the same height-over-bore as standard A2 irons
• Tailored for the AR15/M16/M4 platform

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 not compatible with the MOE Hand Guard.
