  1. Shane Harvey (verified owner)

    Easy to use and works great.

  2. Anonymous (verified owner)

    Well made and very easy to install and remove.

  3. Kenton F. (verified owner)

    Great mount. Quick on and off ability.

  4. Don (verified owner)

    Great idea with poor execution. The metal is so thin on the light clamp that the threads pulled out just snugging the screw. The rail portion has no adjustment and while it probably won’t fall off it is loose and rattles.

  5. Anonymous (verified owner)

    Holds light securely, but mine pinches we if I am not careful when putting it on and taking it off.

  6. Nathan C. (verified owner)

    Build is awesome. Idea is awesome. However, it doesn’t fit my picatinny rail. I have tried a couple different brands of rails and none seem to work.

    • Dianne

      I’ll have warranty contact you.

  7. Robert S. (verified owner)

    Nice as long as you have the picatanny rail to mount to.

  8. Kris K. (verified owner)

    Works as advertised. No arguments here.

  9. Eddie H. (verified owner)

    Good sturdy mount. Easy to use.

  10. Mark C. (verified owner)

    Great for additional utility of your Fenix light!

  11. Nick

    Nice quick release but it is quite bulky, especially when using with an off-set rail. I’ve got the PD36R squeezed in this thing and it is a SUPER tight fit. But it works. I did strip the screw, which did not take much, but I added a nut with blue Loctite and it’s fine.

  12. Michael S. (verified owner)

    Excellent craftsmanship, no complaints.

  13. Shawn Cohen (verified owner)

    Works well

  14. PAUL (verified owner)

    It works but it can be little bit loose on the rail. It has a squeeze on and squeeze off slide. Have to go to the range still.

  15. Clay (verified owner)

    Really like this

  16. Anthony Bautista (verified owner)

    The finish and quality of the mount is great however the fit on picatinny rails has too much slop. When locked in there is play that can not be removed. For a light it is probably fine but on a firearm where there is a lot of jerking, the slop can become more prominent over time. I will keep this on and if it ever breaks I will likely look to see if an improved version has been created.

  17. Mark Anthony (verified owner)

    Love, it works great ! ! !

  18. Carlos E. (verified owner)

    High quality material and parts that are easy to install. This help me avoid buying a firearm flashlight for my pistol.

  19. Pascal Cao (verified owner)

    Very happy with the purchase

  20. Kevin K. (verified owner)

    Works Perfect

  21. Anonymous (verified owner)

    Solid mount

  22. Kevan Western (verified owner)

    Very good mount.

  23. Matthew M. (verified owner)

    Does exactly what it should. I’d prefer if I didn’t have to take the clip off the light. A quick release for the light itself would make it even better.

  24. Chip W. (verified owner)

    Love how easy it mounts and dismounts.

  25. Glenn McGowen (verified owner)

    Easy to use

  26. Joshua L. (verified owner)

    Works as it should, good price great quality as it always is from Fenix

  27. Orrin Mullennax (verified owner)

    Well built!

  28. Jonathan M. (verified owner)

    Great mount, solid and a nice quick release mechanism. Use it with the TK22 UE light and it works great.

  29. Adam (verified owner)

    All I can say is that it’s bulky. When you are running platforms that are maxed out with the thinnest material possible it’s just plain large and I think could easily be trimmed down. However, it works fine, nothing cheap or flimsy about it. Just be Dang sure your torch is gonna fit because it fits a full sized torch.

  30. Bryan S. (verified owner)

    Love this thing. Very easy to put on and take off

  31. Justin Johnson (verified owner)

    This is a solid rail mount for a flashlight. I’ve found just about all of the Fenix lights I own fit in the mount with the exception of those not listed as compatible. Any 1913 picatinny rail will work. I’ve tried it on all of my Sigs, Mossbergs, Smith & Wessons, Rugers, you name it. Mine currently is on a Mossberg 590A1 and houses the Fenix TK26R. That setup works great for home defense. It’s a great price too which means you can pick up a few if you have multiple rifles. However, it’s super easy to take it off one rifle and put it on another, so purchasing just one will suffice too. There is so much to like about the Fenix products. They offer a complete setup for just about every aspect of life.

  33. George P. (verified owner)

    Nice fit!

  34. Anonymous (verified owner)

    Not a very solid hold on the Picatinny rail. Wiggles more then I would like. Also the flashlight is secure in the mount but I could see It moving forward do to the ruber

  35. Michael Lipscomb (verified owner)

    Does it’s intended purpose. However, I find it a bit too wobbly when attached to my rail. I’m of the mindset there shouldn’t be ANY play when mounted.

    • Dianne

      Hi Michael – we are not sure if you are saying the rail mount itself is wobbly (something I personally have not heard of previously), or that the light is wobbly in the mount? If it’s the light, the rail mount has an adjustable diameter that allows you to use any flashlight that is 0.9”-1.02” (22.5-26mm) in diameter.

  36. EDGAR (verified owner)

    Fits just right!!

  37. Anonymous (verified owner)

    I love the quick on and off feature. Very solid.

  38. Brian (verified owner)

    Excellent fit! Exactly what I expected at a fair price.

  39. Xavier J. (verified owner)

    Works good!

  40. Daryl A. (verified owner)

    Great quick release mount, very easy to use and holds light very securely. My only complaint is that it doesn’t sit tightly to the Picatinny rail and wobbles around.

  41. Thomas S. (verified owner)

    Secure and options to remove from gun quickly

  42. James D. (verified owner)

    Fits properly and works well.

  43. Anonymous (verified owner)

    Excellent mount!

  44. Matt R. (verified owner)

    Fit great

  45. Karl O. (verified owner)

    This fixture holds the flashlight securely and easily attaches to the the rail.

  46. Russell Burris (verified owner)

    Spring loaded so not quite as secure on a weapon but it does work good on a picatinny rail.

  47. Jay G. (verified owner)

    Seems the useful diameter is WITHOUT the rubber spacers installed. That’s the only way my tac light would fit.

  48. Anonymous (verified owner)

    Fits easy and securely. A little wiggle on standard picatinny rail but definitely worth the money.

  49. Anonymous (verified owner)

    I ordered 2 of these. Very happy with the design and price. I am a little disappointed in the qd style rail mount. They are looser than i would prefer but overall happy with my purchase

  50. Anonymous (verified owner)

    Will not slide onto my rail

  51. Paul S. (verified owner)

    As described. Great product.

  52. Robert M Pallatto (verified owner)

    Fits flashlight very well, snug and secure. Nice QD, works well .

  53. Bobby P. (verified owner)

    Holds light very secure, light weight and well built. QD is also a big plus to be able to transition if needed. Not a big issue, I think screw on side could be a little shorter, great mounting system!

  54. Nathan (verified owner)

    This fits all 1 inch flashlights. The size is adjustable in case you want it to fit a smaller or bigger mount. I was looking for a smaller width so I went with another product from Fenix. The ALG-01

  55. Michael (verified owner)

    Works great and super easy to install and remove!

  56. Abraham Najera (verified owner)


  57. JOHN (verified owner)

    Very user friendly. Mounts secure and easy.

  58. Stephen (verified owner)

    Very nice rail mount that holds the flashlight solidity.

  59. James S. (verified owner)

    Great product. I would recommended.

  60. Gregory S. (verified owner)

    A solid, easy to use rail mount.

  61. Kevin D. (verified owner)

    Fantastic mount. Function is perfect! Well executed, Fenix!

  62. Mark M. (verified owner)

    Best QR rail mount I’ve tested and have been through a few. Holds the light extremely solid and locks tight to the rail. Outstanding quality 👍

  63. Cody Pierce (verified owner)

    Tensioning bolt stripped.

    • Dianne

      Hi Cody – someone from warranty will reach out to you.

  64. Michael H. (verified owner)

    Haven’t mounted it yet, but it looks sweet.

  65. Anonymous (verified owner)

    Quality product

  66. David Hopkins (verified owner)

    This is an excellent mount it is so easy on and off, just pop it off and through it on any other gun with a rail or just use it in your hand on a retrieve.

  67. David Salch (verified owner)

    What an excellent innovation…the locking mechanism is consistent on the rail so a laser mount works well

  68. Travis Kimrey (verified owner)

    Very well built

  69. ROY Y. (verified owner)

    Tensioning bolt stripped bummed, great quality otherwise


    Does not fit my picatinny rail.

  71. Anonymous (verified owner)


  72. Renato G. (verified owner)

    This item would be great. But it fits loose on my rail. I’ve had to add electrical tape to the rail in order to get a tighter.

    • Dianne_G

      Sorry to hear that Renato – I will have someone from warranty and repair contact you to see if there’s anything missing that will help that.

  73. Greg (verified owner)

    Nice for the price

  74. allen embry (verified owner)

    this works great

  75. Andrew M. (verified owner)

    Works well but must be slid on from the end of the rail – can not be mounted mid rail (at least not by me) which can be annoying.

  76. Ronald Spilker (verified owner)

    Have used the mount with 3 different lights on an AR15. Firing a mix of 556 and 223, have gone through over 500 rounds. One of the lights died, one works but is wonky now, and the other is fine. The mount still seems 100%. No issues at all so far.

    Holds securely. Pretty easy to put on and take off of rails.

  77. Jaimi (verified owner)

    This is a great mount and my only suggestion would be to add a second shorter cap screw for narrower lights, the existing screw is to long and infers with the capability of easy quick mo8nt on and off for smaller hands

    Many thanks for your consideration and excellent products

  78. Mike

    Fits several flashlights, easy on and off and is secure when mounted to the rail. Nice job.

  79. John

    I have the ALG-00 and truly enjoy the versatility it provides.
    Fenix, we understand that you have rail mounts and other accessories listed with each flashlight. But to help your customers, please add a list of compatible Fenix flashlights for this mount, so customers don’t have to check the diameter size of each flashlight to see if it fits.
