I have my old duty ASP Triad CR bored for 18650 as my home weapon light and its has held up well on a deployment and now on my ARX. I also just had a Nailbender P60 in a Solarforce host and it serves well except I dont care for it being 2 mode. The ASP light it perfect because it is a single mode with a twist tailcap to select momentary only or FWD clicky on. Sturdy light and not badly priced.
