Magpul MAG1166-FDE MBUS 3 Sight Front Flat Dark Earth Flip Up AR-10/AR-15/M4/M16/M110/SR-25

Significantly reduced in size from the MBUS, it sits at just 0.47 high when folded, 1.38 at its widest point, and weighs a scant 25 grams with hardware. Its aesthetics are derived from the MBUS Pro, but the MBUS 3 Front Sight is constructed of our impact-resistant polymer, making it lightweight and extremely durable. Featuring the same spring-loaded technology as its predecessor, they can be deployed with an ambidextrous push-button. The MBUS 3 Front Sight sits at standard AR-height when deployed and includes tool-less elevation adjustment of a dual width enhanced front post similar to the MBUS Pro. 1 MOA (1.131″/100m) per click with a 14.5″ sight radius. 0.7 MOA (0.820″/100m) per click with a 20″ sight radius. 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. Made in the USA.
