The XS Tritium Front Sight for AR-15 rifles brings a new level of precision and visibility to your shooting experience. Crafted from stress-proof steel, this front sight is not just tough; it's designed to stand out in any lighting. Whether you're shooting in bright daylight or low light conditions, the tritium makes sure you're on target. Each full turn of the front sight post adjusts your shot by 5 inches at 100 yards, giving you the precision you need for accurate shooting.

This sight fits snugly into AR front sight housings with a front sight detent at 3, 6, or 9 o'clock, making it versatile for various setups. However, it's important to note that it doesn't fit the ARMS back up sight due to the blade's length. Whether you're upgrading your rifle for better performance or personal preference, this front sight is a game changer for your AR-15.
