Surefire X300 Ultra LED 600 Lumen Weapon Light Product Info

The powerful and versatile X300 Ultra LED 600 Lumen Weapon Light features a high-performance LED that generates 600 lumens of stunning white light focused by a Total Internal Reflection (TIR) lens to produce a tight beam with extended reach and significant surround light for peripheral vision. The virtually indestructible and highly efficient LED on this Tactical Weapon Light from Sure Fire generates tactical-level light-more than enough to overwhelm an aggressor’s dark-adapted vision-for 1.5 hours per set of batteries. The high-strength aerospace aluminum body on the Sure-Fire 600 Lumens X300 Ultra Weapon Light is Mil-Spec hard anodized for superior toughness and is O-ring and gasket sealed to make it weatherproof. This Sure Fire Gun Light is also versatile and can be attached to a pistol or a long gun since its Rail-Lock system permits rapid attachment to and removal from either Universal or Picatinny rails. Its integral ambidextrous push/toggle switch provides one-finger operation for either momentary or constant-on operation. Optional DG grip switches are available for use with a pistol, and an XT07 tape switch permits the SureFire X300 Ultra Gun Light to be activated when attached to a long gun without altering your grip on your weapon.

  1. Patrick

    Big Tex Outdoors sells great products and Ike (and crew) provide best-in-class customer service.

  2. Wyatt

    I like the light – but it is shooting loose sometimes. Kinda disappointed in that aspect and wish I had gone with the x300 B

  3. Cantrell

    Big Tex Outdoors had the lowest price I could find on the Surefire X300U-A. Once I placed my order the weapon light was shipped quickly and I received it a just a couple days.

  4. Charles

    Awesome light. Combines the feature of the X300B version, such as 600 lumen output and more robust activation switches, with an easier to attach/detach lever mount, which doesn’t require tools (e.g. a coin, etc.) to mount/dismount and is tailor made for polymer framed handguns. AAA+++ there. The B version is best for picatinney rails, such as shoulder fired Carbines, but is still nice.

  5. Frank

    One of the best online purchasing experiences I have had to date. Excellent price, warp speed shipping, and I like sending my money to good people. Read up on the company, and you will understand what I mean. Forget buying via amazon or some other large, impersonal vendor… Big Tex Outdoors is doing it right.

  6. Austin

    I ordered from Big Tex while I was ordering Ike took the time to inform of a sale code going on for Surefire. Not only does he carry great products but he looks after his customers. Good company good people and will definitely continue to use Big Tex Outdoor and recommend them to everyone

    Was shopping around for a Surefire X-300, BigTex outdoors had an article on the differences between the X300a and b models. Article was informative and helped me in my buying decision. BigTex had an excellent price on one so I bought it right away! Very pleased with the website and ease of ordering.

    Purchased my first Surefire WML on 10-06-2017 and received it a short time later. The product speaks for itself. Got an unreal deal from Big Tex Outdoors. Prices are always the best you can find. Keep an eye out for promos and discounts.

  13. Cam

    Great customer service! I ordered a tan Surefire X300 Ultra, but then decided on black. A quick email solved the problem and Big Tex was happy to swap out the different model. Highly recommend Big Tex
