Blitzkrieg Components AR Spike FSP - Black w/ Tritium Dot



This replaces standard A2 style sight posts in any typical AR-15 type fixed or folding sight. The Blitzkrieg Components AR-15 Spike Front Sight Post for AR-15 sights provides superior sighting with a sharp aiming point and a bold, fast sight picture. The sharp aiming point enables precise aiming and high confidence on difficult shots. The Tritium Dot provides 24/7 night capability. Minimum adjustment for elevation is 4 clicks or one full rotation since the Tritium Dot is visible on one side. This means that when zeroing your sight for elevation, you will be at least within 2 clicks or 2.5 MOA of a perfect zero and normally closer than that or even dead-on. It will be either exactly on point of aim or no more than 2.5 MOA high or low (2.5" at 100 yards, 1.25" at 50 yards). This will vary depending on sight radius.

Our sight posts are precision machined from billet 416 Stainless Steel for an outstanding sight picture and precise fit in any AR-15 front sight housing including standard A2 fixed front sights and popular brands like Troy, Diamondhead, Samson, MI, YHM, Daniel Defense and Magpul plastic MBUS Gen 2. Fits anything that accepts a standard A2 front sight post. Has a matte black melonite finish which is very durable and very corrosion resistant. Simple Drop-In installation. Simply unscrew the factory sight post and screw in the Blitzkrieg Components sight post using either our sight tool or a standard A2 sight tool.

Tritium Dot: The Tritium Dot is installed by Trijicon® and is .062" in diameter, which is the same size as the Tritium Dots used in our Tritium Chevron Sight Post. These provide a 24/7, always-on night capability.
