NOBUHIROM300B 520 Lumens Tactical Flashlight, with Replaceable Mounting Rotating Base, Suitable for 20mm Picatinny & Mlok/Keymod Rail, Include with Remote Pressure & Push Button Switch (M300B)

The light is really good. Especially for the price being a SF repro. My only issue was that the picatinny mounting screw stripped the first time I put it on, but found replacement screws from Home Depot.

Pleasantly surprised with the quality! It could be brighter. Also the allen head screw for the picatinny mount is TINY. Afraid it might strip. It doesn't seem to be 600 lumens (I have another that claims to be 400 lumens that seems brighter!) but is seemingly bright enough for my needs. Body and mounts are nice (except for the size of the allen head). Switch and tail cap are good quality as well. Size and weight are excellent. Holds in place well thus far and IMO, and seems like it will work consistently, when you need it. If so, you can't go wrong for $60. I'll likely be buying another. While I'd like to buy the premium brand, we all know who that is, it's 5x the price, without 5x the increase in quality and performance. Paying that much for a scout light is really hard to stomach...let's hope this one holds up, if so, awesome.

So far so good

Pic rail mount is very weak and cheap feeling. Get a longer screw and that might do the job. But so far the screw doesn’t seem to mount the rails strongly

Review is for the 340A:Not as bright as the 300C that impressed me enough to try this one even though this 340A claims to have almost twice the lumens.Update: I mounted the 300C on a firearm and shot with it attached. The light stayed on the entire time with no flicker or shutting off when firing. All the mounting hardware held up good as well. Tho, where part of the light was exposed to muzzle flash the finish almost immediately dissapeard. This isn't a deal breaker as the body is aluminum, and this costs 1/6 what a surefire does. I still maintain that the 300C is the best option, with the 300B being a close second. The 300B is about a half in shorter, the beam is about as bright despite claiming to be more lumens, but it does have a larger flood.

It's not a Surefire, but it is a good budget clone. If you are using this for your duty rifle, buy the name brand. If you are just after a decent light for plinking this one is great.

No problems with the light. It’s slim, light, and bright. Push button is good.Mount however, needs some work. Include m lock screws are tiny hex heads. They scream strip me, and the connectors are very tiny, they barely lock in. No issues. Into the parts bin for other screws and mlocks. Fit just fineThe problem is the main mount screw. Plus that you can “switch” out between attachment styles. Minus. Big minus. It’s a screw that holds this mount in place. This does not tighten down with confidence it will stay tight. Under recoil and general living this will flop to the side.Loctite the snot out of it. Tighten down hard, it now will hold.For the price of a cheap scout light to throw on a rifle that did not have one, it’s ok. If you need a light cheap, this is not it

This lights have become very popular now and they do have great quality for what you pay for them, then the original, as for the mounting is solid, as for the brightness not as bright but had a good decent hot spots and is white balance instead of yellow, but for home defense it’s enough to do the job
