OLIGHT E-WM25 Offset Professional Flashlight Mount Compatible with The Tactical Flashlight Warrior 3/ Warrior X PRO and Flashlight with Body Diameter of 24.4mm to 27.4mm

Works as expected. Use it to hold a head lamp to the back of my crawlspace robot. It's compact size is perfect for my needs.

Easy to set up and easy to remove. It’s part metal and part polymer so I’m not sure you’d want it for duty use but it’s just fine for my needs.

So I couldn't get a decent answer to my question so I'm posting it myself, having "bit the bullet" and ordered without my answer (you're welcome O Light, suggest you do better)The reason I asked, is because I have a rather cheap but decent and mass produced tactical flashlight my dad ordered from QVC (or something :] ) here's a link to the equivalent. https://www.amazon.com/dp/B00THMIJZU/ref=cm_sw_r_cp_apa_fabc_81H5BYYJG08B1MR1V56Z?_encoding=UTF8&psc=1As you can see. The turned 1 in OD band/section of this light is narrow/not long. Anyhow you can see the width or length is 20mm. I got this McDonalds of tac lights to work with this mound but u had to file down the rib closest to the adjustable head. Didn't take a pic of that but if you buy both parts of this setup it should be clear to you what I'm talking about once you start monkeying with them.Anywho...pretty happy with the result but haven't done much in the way of field testing. 😅 it's a good budget setup.Hope that helps somebody else!!

I could break this off with my hand. Made of plastic except for the ring. Does keep a low profile on the rail but the adjustment knob is big and feels cheap. I could easily bend this so reliability is highly questionable. If durability is what you're looking for I wouldn't go with this imho. Does hold my light though.

Attaches quickly to all of my torches, with included adapters.

I got this to side mount a 1" green laser on my 12g shotgun. I specifically loved the low profile offset. A lot of other offset mounts place the item above the rail. Not so with the O-Light. After installing it looked great on my gun!I had concerns after the cosmetic admiration wore off. The tool-less design is convenient, but not great if you need a solid clamp on your device. The plastic knob can only be dialed in so much, and the awkward pull-out-and-twist mechanism made if difficult to get the mount to a point where I thought it tight enough to hold zero. Another concern is there is a single mechanism both for attaching to the pic rail, and securing your device in the mount. So a finnicky dial is doing double duty.Well, after a day at the range, the laser has completely shifted within the mount, and the whole mount is tilted. So yes, it's a 12 gauge, and there's a lot of recoil, and I bought this for something that needed to hold zero—so perhaps the blame is on me. Cosmetically, this thing looks great, and I love the tucked in profile. It's just not designed for anything that needs to hold zero under high recoil.

Prefect fit for my olight and rail

If you're using an old light obviously these fit your flashlight better than just about anything out there. I love the position they put your flashlight in on your firearm. No matter where I mount it it seems to be just in the right spot just at the right angle for me to access it. There's other weapon light mounts that I wanted to like more than this. But none of them put the light in the position that I wanted it to be in. So I ended up sending them back and I kept this one and ordered another. It doesn't feel quite as sturdy as some of the other brands, but it hasn't broke yet either so it must be sturdier than I think it is.
