$30 light https://www.amazon.com/gp/product/B09366BHFM

I've been flip flopping this week on a light for my CZolt 6920socom.

Real SF M951? $120 used from ebay, but massive by modern standards and shit runtime/lumens. Needs LED upgrade, and body bored to accept 18650. Also need the $100+ pressure pad, which I'd prefer to get authentic.

Amazon fake $50. Includes spare pressure switch. Already had LED (these are all P60 hosts, hot-shit dropins are almost free) and I only need to change the driver to direct (with a thermistor) and bore the body to accept 18650. https://www.amazon.com/gp/product/B099KM4NPC

I've been running Chinese Cree lights for around 20 years now, huge inventory of spare parts, lots of experience with modes of failure. For $9 from Fasttech, they're impossible to beat. If it weren't a clone rifle, I'd have gone with an ultrafire 501 and 2 mode clicky XD
