Magpul MBUS 3 Sight Front Rifle Sight Black MAG1166-BLK

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. Compatible with AR-10/AR-15/M-4/M16/M110/SR-25
