The Surefire X300U is a popular weapon light among gun enthusiasts and professionals in the military and law enforcement. The X300U comes in two versions: A and B. While they may look similar, they have some differences that may affect your decision on which one to choose. In this article, we will compare the Surefire X300U A vs B to help you make an informed decision.
Overview
Both the X300U A and B are 600-lumen LED weapon lights designed for pistols and long guns. They are compact and lightweight, making them easy to mount and operate. They feature a patented TIR lens that creates a high-intensity beam with a tight center and significant surround light. They also have a quick-detach rail clamp that allows for easy installation and removal.
Body and Mounting
The main difference between the X300U A and B is the body and mounting system. The X300U A has a universal rail mount that fits most pistols and long guns, while the X300U B has a proprietary mount that only fits certain guns, including the Glock 17, 19, 20, 21, 22, 23, 31, 32, and 37. However, the X300U B has a slimmer body that is more streamlined and less likely to snag on clothing or equipment.
Switch
Another difference between the X300U A and B is the switch. The X300U A has a push-button tailcap switch that provides momentary or constant-on activation. The switch is located at the rear of the light and is easy to access with your thumb. The X300U B, on the other hand, has a switch located on the side of the light that can be activated with your trigger finger. The switch is ambidextrous and can be programmed for momentary or constant-on activation.
Battery
The X300U A and B both use two CR123A batteries, which are readily available and easy to replace. However, the X300U B has a longer battery life than the X300U A. The X300U B can run for 1.5 hours on high mode and 60 hours on low mode, while the X300U A can run for 1.5 hours on high mode and six hours on low mode.
Price
Finally, the price is another factor to consider when choosing between the X300U A and B. The X300U A is slightly cheaper than the X300U B, but the price difference is not significant. You should choose the one that fits your budget and meets your needs.
Conclusion
So, which one should you choose? It depends on your needs and preferences. If you want a universal mount and a push-button switch, go for the X300U A. If you have one of the compatible guns and want a slimmer body and an ambidextrous switch, go for the X300U B. Both lights are high-quality and reliable, so you can’t go wrong with either one.
