The NCStar AR-15 45 Degree Offset Flip-Up Front Sight (part no. MAR45FLF) is a black backup iron sight built for AR-15 shooters who run a magnified optic on top of the rail and want fast-transition offset irons underneath it. It mounts to any receiver-height Weaver or Picatinny MIL-STD 1913 rail, sitting at a 45-degree angle so it’s out of the way until you cant the rifle to use it. The A2-style front sight post is fully adjustable for elevation, and the sight folds forward flat for a lower profile when not in use.
