Night Fision Tritium Front Sight Post Yellow Ring for AR15

Upgrading your AR15's front sight to tritium technology gives you reliable aiming in darkness without batteries or charging. The Night Fision yellow ring post delivers fast target acquisition across lighting conditions. Whether you're in San Jose or anywhere in California, understanding your firearm setup matters—review California firearm laws before modifying your rifle.

Tritium Visibility Without Electronics

Tritium self-illuminates continuously through radioactive decay, meaning your front sight stays visible in complete darkness. The yellow ring frames the glowing post, creating contrast that speeds target identification during low-light drills or hunting scenarios. No batteries fail, no electronics malfunction. Installation fits standard AR15 front sight bases. If you acquired your rifle through a private sale, TacticCAL can assist with proper private party transfer process documentation in compliance with state requirements. Browse our firearms dealer.
