Tacfire's 45 degree iron sights are constructed of T6 6061 Black anodized aircraft grade aluminum for strength and durability. The front sight has an adjustable A2 post with a spring-loaded feature so that with just a push of a button they will easily flip-up into position & locks into place to guarantee zero. The rear sight has dual apertures for use in short and long distance shooting. These sights would be a great choice if you would like to quickly transition from using optics to iron sights by just canting your rifle to a 45 degree.
