The XS Sights AR-15 A2 Tritium Stripe Front Sight (XS Sights part no. AR-2001-6) swaps the standard post on an AR-15 for a tritium-powered sight that stays visible in low light. It has a square-top post that is 0.105 inch wide, a good match for shooters who prefer a traditional sight picture. The sight is made from stress-proof steel and fits snugly into AR front sight housings. It is a simple upgrade for a home-defense or general-purpose AR with an A2-style front sight base. The tritium carries a 12-year warranty.
