Description

The powerful, virtually indestructible X300 Ultra WeaponLight was primarily designed for handguns but is also excellent for long guns and mounts securely to MIL-STD 1913 rail-equipped rifles via its newly enhanced T-slot mounting system. This top-selling WeaponLight features a high-performance LED that generates 600 lumens of stunning white light that’s focused by a Total Internal Reflection (TIR) lens to produce a high-intensity beam with extended range yet it provides significant surround light for peripheral vision in close quarters. The highly efficient virtually failure-proof LED generates tactical-level light-ideal for close- to long-range target identification-for 1.5 hours per set of batteries. Activating the X300 Ultra is done via intuitive, ambidextrous switches-now wider and shorter for improved ergonomics-at the rear of the body. Simply press the switch on either side for momentary-on activation or flip up or down for constant-on activation. Optional DG grip switches (for handguns) and pressure-activated XT tape switches (for long guns) permit the X300 Ultra to be activated remotely. The X300 Ultra can be securely attached to a handgun or a long gun via its new and improved T-slot mounting system. Universal and Picatinny crossbar wedges are included for simple, foolproof installation. Its high-strength aerospace aluminum body-including the mounting system-is Mil-Spec hard anodized for superior toughness and it is O-ring sealed, making it weatherproof. FITS: The new T-slot mounting system fits most railed handguns (and rail-equipped long guns) but adapter mounts are available for some non-railed handguns.

    • Solid light
Solid light. Excellent reach and super bright. If using at night, it acts as a laser because it’s so bright the beam is so focused. The build is solid and has a great weight. Even after getting off many rounds, it stays in place with zero wiggle. While it is more expensive than the competition, you get what you pay for. My one complaint is that the batteries load from the back so when you need to replace them, you need to remove the light. ... show more

    • Super Rugged and Dependable.
Awesome light that is super durable. Seriously, I dont think you can break this light. It is worth the money. The focus on the beam is super tight with an awesome candela and lumens. It doesnt get overly hot. Get rechargeable batteries!

    • It's a SureFire, so you already know it nearly indestructible and awesome.
Color: Black Mounting Type: T-Slot Mount Set name: Hybrid Beam
It's a SureFire, so you already know it nearly indestructible and awesome. The price is crazy high, but how much is a reliable parachute worth when the plane's on fire? What happens if it doesn't work when you need it? Fits on Glock or 1913 Pic rail with included cross-bars for each. Fastens with a thumb screw which can be tightened with a penny or Tasco chamber flag. Rule 4 of firearms: Be certain of your target and what's beyond it. If it's dark, how are you going to do that without a weapon light? If you plan to hold a $5 flashlight from Wal-Mart, will you really have 6 hands in order to hold a gun, reload, call 9-1-1, carry a child, open a door AND hang onto a flashlight? Fact: Evil prefer darkness. This take away that advantage in a instant. Yes..yes...it's not easy to carry a pistol with a light, for a number of reasons. However, every rifle should have a white light and every pistol that is not normally carried on your person should have one, too. I can hear the keyboards clicking already. "But won't this light give away my position?". Yes, it will. But so will your gunfire a split second after the light goes on. Also, 1) In all likelihood, the adversary already knows where you are and is preparing to engage you while you are still trying to identify/assess the threat in darkness. 2) This light is crazy-bright and will blind anyone at close range for a few seconds 3) you don't need to (and shouldn't) leave it on all the time you are facing possible threats. It can be turned on just before firing in order to absolutely confirm your target is a threat 4) get some training on how to use it properly. BTW, you still need a hand-light light, because it's not polite/smart to use a gun as a flashlight unless you may need to shoot what is illuminated. So, don't use a weapon-mounted light to look for a puppy in the park or a kitten in a neighbor's tree. Last point, you can put this in your pocket and use it as a hand-held, but don't think you are going to attach it to something shooty during the 4 second bullet swap in which you might need it. ... show more

Color: Black Mounting Type: T-Slot Mount Set name: Hybrid Beam
Not sure if it’s the seller or what but do not purchase. Light is VERY cheaply made and as soon as I opens the battery lid, it was off track and broken. Sent back on July 1 for credit so I could order a brand new one, however they are still processing my return/exchange as of 7/9, and now it’s another delay and I May get my refund/exchange 7/19. 300$ light and it should work while also being made durable enough to open the battery door.

    • Great Handgun light!!! Must have for any tactical shooter/home defense
Fantastic light. easy to install on any handgun with a rail. I put this on one of my 1911 handguns, and it fit perfectly. The fit is snug and there is no wiggle or movement once the light is installed. I looked around and found this light on Amazon. Every other seller had the same light for about $70 more, so this was a deal at the price I paid for it. I have the X300U-A as well and it has a little wiggle to it when installed and a broad beam. The X300T-B has a narrow beam that makes it easy for target acquisition when shooting at distance. In my opinion these are the best handgun lights on the market. A lot of companies make holsters compatible for this weapon light as well. ... show more
