Simple Sight Picture Draws your Focus to the Front!

We designed F8 Night sights to increase front sight focus by using a large, high-contrast front post for fast sight acquisition. The big, vibrant front paired with a wide-notch rear sight allows for greater visibility of the front post in decreasing light levels. The tritium front sight comes with our proprietary photoluminescent orange Glow Dot, which absorbs ambient light and glows in low light. The figure-8, 2-Dot alignment system simplifies the rear and draws focus to the front sight for accurate indexing. F8 sights are taller than most traditional sights on the market, providing a more natural sight alignment and serving as backup iron sights for pistol reflex sights.

XS F8 Tritium Night Sight offers an excellent notch and post sight picture that will keep your front sight visible day or night. That way, you'll be ready for the fight, no matter the light.

F8 sights were our first venture at a notch and post sight picture. We designed them to utilize the simple alignment and size benefits of our express sight system. They reduce the flaws of many traditional notch and post sights with the large front blade and wider than usual rear notch. 

F8 sights are CNC machined from solid steel bar stock by our in-house machine shop. We design, machine, and insert tritium to produce the highest quality possible and provide American Made products. We are a small, second-generation family-owned business based in Fort Worth, TX, and our customers are family.

We live, eat, and breathe guns. We offer easy DIY install instructions, a 30-Day Satisfaction Guarantee, and stand behind a 10-Year No Questions Asked Warranty on all our sights. If you break your sight training, we want to hear about it. If you damage your sight installing it, give us a call, and we will get a new one mailed out after a friendly lecture from one of our gunsmiths. If you have color vision issues and can't see the front dot, call us, and we will get another set shipped out. (Over 5% of the population has color blindness to a degree!) Either way, our products are built to take a beating, and we will have your back if anything happens.

    F8 on M&P Sheild

    Best night sight! Super bright in total darkness. I may have damaged the front sight upon installation because it didn't glow and looked damaged. I emailed XS, got a response same day, s new front sight arrived three days latter! Customer service is equal to the quality of their product! I will only purchase XS products in the future. Many thanks to XS! If only they made firearms.

    F8 sights

    Posted by J. J. Isherwood on Jul 2nd 2022

    These are excellent sights with excellent customer service. The Big Dot DXT's are probably a better fighting sight if used under bad environmentals or while moving/clearing a building. But the F8s are a good compromise between traditional notch and post to use on the range and the Big Dot. They allow rapid acquisition with a very prominent orange dot on the front while also preserving aiming for longer distance shots (the DXT's CAN be shot at longer range accurately but take a very conscious effort to line up the dot exactly tangent to the wide V--great for night or bad envrions or fighting from difficult positions but somewhat harder to work day VFR on the range). The F8s sit fairly proud and can be used to help rack a slide if necessary; very well built and rugged. IF you're looking for a traditional type of sight which can be rapidly acquired along with a good straight-8 configuration these are the sights to get. Mounted on a Glock 33.
