SureFire M640 DF-Pro Dual-Fuel Scout Light, 1500 Lumens, Black, Pick/Hunting Firearm Mount, Tactical Flashlight (M640DF-BK-PRO)

High quality and powerful little light. Too bad there’s no way to put a quick- disconnect mount on it. Otherwise, very happy with my new light.

The SureFire M640DF Scout PRO is an exceptional weapon light, offering incredible brightness and durability. With 1500 lumens, it provides outstanding illumination for both close-quarters and extended-range use. The dual-fuel capability is a huge plus, allowing flexibility with rechargeable and disposable batteries. The mounting system is solid and versatile, making it easy to attach and adjust for optimal placement on my firearm. It’s built tough, as expected from SureFire, and handles recoil without any issues. Definitely worth the investment for anyone serious about tactical gear or personal defense.

Will causing low output and flickering if used in conjunction with any of the tape switches offered by surefire. This is a known issue and the engineers are still working on a solution... Really unsure how this product got to market without being tested with the accessories they recommend with it... SR07 tailcap is what I used and found the flickering.I got this model so I wouldn't have to buy extra mounts also (all in one package) but I sorta regret not getting the other normal model to go with the Arisaka mounts. Thought I researched this stuff enough to know what I was getting into but do you research before you buy.

I bought a new AR15. So I knew it needed a weapon light. I went back and forth between the Surefire and the Streamlight Protac HL-X. Yes the HL-X is literally less than half the Surefire. But what sold me was first the Surefire warranty. Buy one FOR LIFE. They will update it to a new version if you have issues 5, 10 years from now. Whenever. Second, you aren’t going to get a smaller weapon light that clears the rail. It’s hardly noticeable. The Streamlight is amazing but it’s still bigger. And last. This sucker is BRIGHT! At 1500 Lumens. I think if something goes bump in the night. This would give you a sheer heart attack flashed into your face. So here’s my final point. Surefire is expensive because they are worth it. Stop going back and forth like I did. I promise you once you get it installed you won’t be disappointed!

You can shop for deals but price is usually not the factor when shopping for true and tested products. This is not a spotlight so beamIs not concentrated but if needed you can buy one that is or the accessory head. Love the dual fuel meaning I can use 2 CR should I run out of charge on my outing. Warranty is a plus along with being made in America 🇺🇸 supporting local infrastructure and businesses.

The light is fantastic pricey but if you happen to find it at a reduced cost around Black Friday or something I wouldn’t hesitate doesn’t have the laser like focus of the okw head but will definitely do what you need it to do

The 1k lumens is awesome. Great for blinding and umbrella lighting. Love the dual source. Always prefer multiple power options for any tool.

I haven't personally tested this light so I can't speak to it's performance aside from review comparisons. I'm sure it performs to what it is marketed to. Unfortunately it has poor throw from what I've read.The mount is neat, but just get a Modlight instead. They're slightly cheaper, made in USA as well, and perform far better. They're even compatable with Surefire switches, although the Modlight switches are higher quality. Out of the box they come with the internals that are sold as an upgrade to put into Surefire switches. Arisaka also sells a dual fuel version. I should have looked into them more before ordering this, but luckily I found out before it was too late.Also, Modlight support is much better.Seriously, unless you need the flexibility of this mount, it simply isn't worth the cost.
