Surefire m640df scout light pro dual fuel led weapon light - SureFire M640DF Scout Light Pro Dual Fuel LED Weapon Light

I have am partial to Surefire products. I have used them exclusively since 2000 after enlistment, and specifically in GWOT campaigns until 2025 when I retired. I have purchased probably four of these scout lights and run them on all my AR and AK platforms. I use the 300 series on all my pistols. You could probably hand them down to your grandkids. Pricey. But good stuff ain't cheap. Cheap stuff ain't good.
